Key Points

• Mid Latitudes generally refer to the regions between 30° and 60° in both hemispheres.
• These areas experience the greatest differences in weather and temperature between the seasons due to their position relative to the equator and poles.
• In the mid-latitudes, the tilt of the Earth's axis causes more pronounced seasonal changes compared to low latitudes (tropical regions).
• Examples of mid-latitude regions include much of North America, Europe, and parts of Asia, which experience hot summers and cold winters.

Additional Information

• High Latitudes
  • High latitudes are the regions near the poles, typically above 60° latitude in both the Northern and Southern Hemispheres.
  • These areas experience extreme conditions with long, cold winters and short, cool summers.
  • Examples include the Arctic and Antarctic regions.
• Low Latitudes
  • Low latitudes are the regions near the equator, typically between 0° and 30° latitude in both hemispheres.
  • These areas experience relatively consistent warm temperatures year-round and have minimal seasonal variation.
  • Examples include tropical regions like the Amazon Rainforest, Central Africa, and Southeast Asia.
• Subtropics
  • Subtropical regions are located between the tropical and temperate zones, generally between 23.5° and 40° latitude in both hemispheres.
  • These areas experience hot summers and mild winters with a moderate amount of seasonal variation.
  • Examples include the Mediterranean Basin, parts of the southern United States, and southern China.

The correct answer is - Singapore

Key Points

• Singapore's time zone
  • Singapore operates in the Singapore Standard Time (SST), which is UTC+8.
  • India operates in the Indian Standard Time (IST), which is UTC+5:30.
  • There is a 2.5-hour time difference between India and Singapore.
• Time alignment
  • When it is 10 A.M. in India, it is 12:30 P.M. in Singapore.
  • This aligns with the statement that it is "around noon" in Singapore.

Additional Information

  • Karachi
    • Karachi operates in Pakistan Standard Time (PST), which is UTC+5.
    • When it is 10 A.M. in India, it is 9:30 A.M. in Karachi.
    • This does not align with the statement "around noon."
  • Japan
    • Japan operates in Japan Standard Time (JST), which is UTC+9.
    • When it is 10 A.M. in India, it is 1:30 P.M. in Japan.
    • This is beyond "around noon."
  • London
    • London operates in Greenwich Mean Time (GMT) or UTC+0 during standard time.
    • When it is 10 A.M. in India, it is 4:30 A.M. in London.
    • This is far earlier than "around noon."
• Understanding UTC offsets
  • Coordinated Universal Time (UTC) is the primary time standard by which the world regulates clocks and time.
  • UTC offsets represent the number of hours ahead (+) or behind (-) UTC for a specific region.
  • Knowing UTC offsets helps determine the local time in different regions accurately.

The correct answer is - Option 4 (74 km/hr)

Key Points

• Average Speed Formula
  • The formula for average speed is:
    Average Speed = Total Distance / Total Time
• Given Data
  • Total Distance = 1776 km
  • Departure Time = 17:00 on 30th January 2023
  • Arrival Time = 17:00 on 31st January 2023
  • Total Time = 24 hours
• Calculation
  • Using the formula:
    Average Speed = Total Distance / Total Time
  • Average Speed = 1776 km / 24 hours = 74 km/hr
• Correct Answer
  • The average speed of the train is 74 km/hr, which matches Option 4.

Additional Information

• Units of Speed
  • Speed is measured in units of distance per unit of time, such as km/hr, m/s, etc.
  • 1 km/hr = 5/18 m/s when converting to meters per second.
• Key Differences Between Speed, Velocity, and Average Speed
  • Speed: The distance traveled per unit time, regardless of direction.
  • Velocity: Speed with a specific direction.
  • Average Speed: Total distance divided by total time, irrespective of changes in speed.
• Practical Applications of Average Speed
  • Used in estimating travel time for journeys.
  • Essential for planning transportation schedules and logistics.

The correct answer is 'Venus'

Key Points

• Venus:
  • Venus is often called Earth's "sister planet" because its size and mass are very similar to Earth's.
  • Its diameter is about 12,104 km, compared to Earth's 12,742 km.
  • Both planets have a similar composition and density.

Additional Information

• Saturn:
  • Saturn is a gas giant with a diameter of about 116,460 km, making it significantly larger than Earth.
  • It is composed mainly of hydrogen and helium, unlike the rocky composition of Earth.
• Mars:
  • Mars has a diameter of approximately 6,779 km, which is about half the size of Earth.
  • Although smaller, Mars has similar surface features such as mountains, valleys, and polar ice caps.
• Jupiter:
  • Jupiter is the largest planet in the solar system with a diameter of about 139,820 km.
  • It is a gas giant, primarily composed of hydrogen and helium, and vastly different in size and composition compared to Earth.

The presence of the El Nino leads to an increase in sea-surface temperatures

Key Points

• El Nino Phenomenon:
  • El Nino is a climate pattern that describes the unusual warming of surface waters in the eastern tropical Pacific Ocean.
  • This phenomenon typically occurs every 2 to 7 years and can last from nine months to two years.
  • The warming of sea-surface temperatures can have significant impacts on global weather patterns, including increased rainfall in some regions and droughts in others.
• Impact on Sea-Surface Temperatures:
  • During an El Nino event, the central and eastern Pacific Ocean experiences a significant rise in sea-surface temperatures.
  • This increase in temperature disrupts normal weather patterns and can have widespread climatic effects.

The correct answer is Mercury.

Confusion Points

Here we have changed the option in this question as in the official paper mars planet is also there which creates confusion.

Concept:

• Planets:
  • A celestial body moving in an elliptical orbit around a star is known as a planet.
  • The planet of our solar system is divisible into two groups:
• Inner planets or terrestrial planets: they are made up of rocks and metals and relatively have high density. These are basically from Sun to the asteroid belt.
• Outer planets or Jovian planets: Mostly constituting gas.

Explanation:

Planets according to the radius of the Planet:

• Mercury: 2,440 km
• Mars: 3,390 km
• Venus: 6,052 km
• Earth: 6,371 km
• Neptune: 24,622 km
• Uranus: 25,362 km
• Saturn: 58,232 km
• Jupiter: 69,911 km

Hence Mercury is smaller than Earth.

Additional Information

Planets order in Solar System:

      My Very Excited Mother Just Served Us Nachos

M →  Mercury, V → Venus, E → Earth, M → Mars, J → Jupiter, S → Saturn, U → Uranus, N → Neptune

Concept:

Speed: the rate at which things move.

To calculate speed two factors are important:

• The distance covered by an object.
• The time is taken to cover that distance.

So, the formula for speed is:

Speed= distance(km)/time(hr)

Explanation:

Distance covered= 2640km

Time is taken = 4:15 on 5th June 2020 to 03:15 on 7th June 2020

which is, 1 hour less than 48 hours

Time = 47 hrs

so, speed = 2640/47= 56

Thus, the Average speed is 56km/hr.

Important Points

•  Always make sure you are using the right units (according to the question).

Some important conversions:

For minutes to hours:

• Divide by 60

For hours to minutes:

• multiply by 60

From kilometres to meters:

• Multiply by 1000.

For meters to kilometres:

• Divide by 1000

Concept:

• Directions play a very important role in navigation.
• There are 4 major directions:
  • North
  • South
  • East
  • West

Explanation:

• Boy starts from X position.
• Moves 100m north.
• Then, moves 75 m towards west.
• Then again turn towards South and move 100 m.

Thus, with respect to (Y) the school (X) House is 75 m due East. 

Given:

Distance = 50 km,

Total run time = 70 minutes,

Stoppage time at stations = 2 + 4 + 6 + 8 = 20 minutes

Concept:

Average speed = Total distance/Total time

Calculation:

⇒ Total time including stoppages = 70 + 20 = 90 minutes = 90/60 = 1.5 hours

⇒ Average speed = 50 km/1.5 hours = 100/3 km/h

Hence, the average speed of the train between stations P and U is 100/3 km/h.

A shooting star is a meteorite that catches fire while entering the earth’s atmosphere: 

Explanation:

• A shooting star is nothing but meteors burning up when they enter the earth's atmosphere.
• ​The Shooting Star looks exactly the same as the Inverted hammer.

Meteorite:

• A meteorite is a solid piece of debris from an object, such as a comet, asteroid, or meteoroid, that originates in outer space and survives its passage through the atmosphere to reach the surface of a planet or moon.
• Heavenly matter landing on the earth’s surface is known as Meteorite.
• A meteor is simply an asteroid that attempts to land on Earth but is vaporized by the Earth’s atmosphere.
• ​If chunks of a comet melt off as it passes close to the Sun, this debris can be left behind to later dazzle us, Earthlings, with a meteor shower.

Additional InformationStars:

• Stars are a massive self-luminous celestial body of gas that shines by radiation derived from their internal energy sources. 
• The twinkling of stars is due to the atmospheric refraction of star-light.
• The refraction of light caused by the earth's atmosphere having air layers of varying optical density is called atmospheric refraction.
• This causes the light from the star to twinkle when seen from the ground.

Satellite:

An object moving at a constant speed can be a satellite.

• A satellite is a moon, planet or machine that orbits a planet or star.
• A satellite moves at a constant speed around a larger object.
• Earth is a satellite because it moves around the sun.
• The moon is a satellite because it moves around Earth.
• Earth and the moon are called "natural" satellites.

Concept:

• Speed: The distance travelled by the body in unit time.
• \(Speed = \frac{{Distance}}{{Time}}\)
• Also, \(Time= \frac{{Distance}}{{Speed}}\)
• Average Speed: Since the body does not always have the same speed, So we use the concept of average speed. It is the ratio of total distance covered to total time taken by the body.
• \(Average\;Speed = \frac{{Total\;Distance}}{{Total\;Time}}\)

Calculation:

The person was on the train for 3 days.

Total Distance covered = 2200km

Time taken on different days

• On 29^th Oct = 3h 15min
• On 30^th Sept = 24 hrs
• On 1^st Oct = 12 h 45 min

Total time = 40 hrs

Average Speed = distance/ time = (2200/40) = 55km/h

Thus, the average speed of the train is 55km/h.

Concept:

The earth is round there is actually no 'up' and 'down' on the earth and it is just relative. 

Explanation:

• The earth can be divided into two hemispheres, the upper (northern hemisphere) and the lower (southern hemisphere).
• They are just names for specific places on the Earth so that it is easy for us to give directions and find our way around.
• These hemispheres are relative if not defined clearly. 
• An equator is used to divide the earth into two hemispheres.
• If Earth was upside down and no one would really notice, because one would still feel that the ground is down and the sky is up.
• This is because gravity always pulls us towards the middle of the Earth.
• If someone is standing on the earth in India and someone is standing in Argentina they are on the same line through the interior of the earth.
• That's why they are relative upside down.

​

​Thus, we, the people of India, actually stand upside down in relation to the people of Argentina.

Mistake Points

• If we divide the earth into four quadrants on the basis of their relative position North, South, East and West.
• India falls in the NE quadrant, Australia in the SE quadrant and Argentina in the SW quadrant. 
• The opposite of NE will be SW hence the correct answer will be Argentina and not Australia.

Confusion Points

• Libya, Algeria, and Alaska (USA) all lie above the equator in the same hemisphere (i.e northern hemisphere) as that of India.
• Thus, there is no relative difference in location between these countries and India.

Concept:

Direction is divided into 8 sections, 4 cardinal directions, and 4 ordinal directions.

• The four cardinal directions are the directions north, east, south, and west, commonly denoted by their initials N, E, S, and W.
• East and west are perpendiculars (at right angles) to north and south.
• East is in the clockwise direction of rotation from north and west is directly opposite east. 
• The ordinal directions are North-East (NE), south-east (SE), south-west (SW), and north-west (NW).
• NE, SE, SW, and NW lie in between the cardinal directions north and east, south and east, south and west, and north and west respectively.

Explanation:

Thickest forest in India is located in the states of:

• Sikkim 
• Arunachal Pradesh
• Jharkhand
• West Bengal 

If we are in Madhya Pradesh then, the thick forest will be in the northeast direction.

Thus, with respect to Madhya Pradesh, the thick forest will be the northeast direction. 

Explanation:

First from point X one go 125 m south,

Then turn east 100 m

Then go to east 125 m

Hence the X, Y point get opposite to each other.

With respect to school at Y my house X is 100 m west.

Concept:

• Speed: The distance travelled by the body in unit time.
• \(Speed = \frac{{Distance}}{{Time}}\)
• Also, \(Time= \frac{{Distance}}{{Speed}}\)
• Average Speed: Since the body does not always have the same speed, So we use the concept of average speed. It is the ratio of total distance covered to total time taken by the body.
• \(Average\;Speed = \frac{{Total\;Distance}}{{Total\;Time}}\)

Calculation:

Total distance = 1140 km

Total time taken = 21 hr 30 min = 1290 min

We know that,

\(Average\;Speed = \frac{{Total\;Distance}}{{Total\;Time}}\)

\(⇒ Average\;Speed = \frac{{1140\;km}}{{21.5\;hr}} = 53.02 \ km/hr\)

⇒ Average Speed = 53.02 km/hr

The average speed of the train was nearly 53 km/hr
