Consider the following statements regarding Spring Tides and Neap Tides:

1. Spring Tides occur during the First and Last Quarter Moon phases when the Sun, Moon, and Earth form a right angle.

2. Neap Tides occur during the New Moon and Full Moon phases when the gravitational forces of the Sun and Moon reinforce each other.

Select the correct answer using the code given below:

  1. 1 only
  2. 2 only
  3. Both 1 and 2
  4. Neither 1 nor 2

The Correct Answer is Option 4

Key Points 

  • Spring Tides occur when the Earth, Moon, and Sun are aligned, which happens during the New Moon and Full Moon phases.
  • Neap Tides occur when the Sun and Moon form a right angle with the Earth, occurring during the First Quarter and Last Quarter phases.
  • During Spring Tides, gravitational forces of the Sun and Moon combine, causing higher high tides and lower low tides.
  • During Neap Tides, gravitational forces partially cancel each other, causing lower high tides and higher low tides.
  • The tidal range (difference between high and low tides) is maximum during Spring Tides and minimum during Neap Tides.
  • Tides are influenced by the gravitational pull of both the Moon and the Sun, but the Moon’s effect is stronger due to its proximity to the Earth.
  • Spring and Neap tides occur roughly every two weeks, alternating throughout the lunar cycle.

Important Points 

  • The term "Spring Tide" does not refer to the season; it comes from the Old English word springan, meaning "to rise".
  • Neap Tide comes from the Old English word nepflod, meaning "scanty flood".
  • The Bay of Fundy in Canada experiences one of the world's highest tidal ranges due to its unique funnel shape.
  • Tidal energy is a renewable energy source generated from the movement of tides.
  • The Sun’s gravitational pull is about 46% as strong as the Moon’s pull on Earth’s tides.
  • Ocean currents, coastal shape, and local geography also influence the intensity of tides.

Additional Information 

  • The Earth’s rotation and the Moon’s revolution play a crucial role in the occurrence of tides.
  • The Coriolis Effect influences the movement of tides and ocean currents due to the Earth’s rotation.
  • King Tides are extremely high Spring Tides that occur when the Moon is closest to the Earth (perigee) and the Sun is closest to the Earth (perihelion).
  • The gravitational force formula explains the impact of celestial bodies on tides: F=Gm1m2r2F = \frac{G m_1 m_2}{r^2} where FF is gravitational force, GG is the gravitational constant, m1m_1 and m2m_2 are masses, and rr is the distance between them.
  • Some areas experience only one high tide and one low tide per day (diurnal tides), while others experience two high and two low tides per day (semi-diurnal tides)
