Question

When does spring tides occur?
A. During full moon and new moon
B. During quarter moon
C. Only during full moon
D. Only during new moon

Answer 1

Hint:
- Spring tides mean the most extreme tide.
- Around each new moon and full moon, the sun, Earth, and moon arrange themselves more or less along a line in space. Then the pull on the tides increases, because the gravity of the sun reinforces the moon’s gravity.

Complete step by step solution:
In most places, but not everywhere, there are two high tides and two low tides a day. The difference in height between high and low tides varies, as the moon waxes and wanes from new to full and back to new again. The moon and sun are primarily responsible for the rising and falling of ocean tides. However, for any particular spot on Earth’s surface, the height of the tides and their fluctuation in time also depend on the shape of your specific beach and the angle of the seabed leading up to your beach, plus your larger coastline and the prevailing ocean currents and winds.

Around each new moon and full moon, the sun, Earth, and moon arrange themselves more or less along a line in space. Then the pull on the tides increases, because the gravity of the sun reinforces the moon’s gravity. The height of the average solar tide is about 50 per cent of the average lunar tide.

Thus, for a new moon or full moon, the tide’s range is at its maximum. This is the spring tide: the highest (and lowest) tide. Spring tides are not named for the season. This is spring in the sense of jump, burst forth, rise.

So spring tides bring the most extreme high and low tides every month, and they always happen – every month – around the full and new moon.

Note: - Tides are due to the effect of gravitational force.
- Due to the rotation of the earth and gravitational force due to the moon and the sun in most places, there are two high tides and two low tides a day.
