Question

The diagram below shows the positions of Earth, sun, and moon during two types of tides. The picture on the left is labeled Tide 1 and shows the Earth and sun along the same horizontal line and moon above Earth. The picture on the right is labeled Tide 2 and shows the Earth and sun along the same horizontal line and the moon below Earth. What impact do both positions have on the tides?
The difference is greatest between the high and low tides.
The difference is almost equal to the high tide between the high and low tides.
The gravitational forces due to the sun and the moon cancel each others' effect.
The gravitational forces due to the sun and the moon amplify each others' effect.

Answer 1

Answer:

c. the gravitational forces due to the sun and the moon cancel each other's effect

Explanation:

The two diagrams represent Neap tides. Neap tides occur when the Sun, the Moon and the Earth are aligned at right angles. Moderate tides are formed because the bulge due to gravitational pull of the Sun cancels the bulge due to moon. The difference between the high tides and the low tides is the smallest.
