The diagram below shows the positions of earth, sun, and moon during two types of tides.

both represent tides during which (2 points)

a. the difference between the high and low tide is the greatest
b. the difference between the high and low tide is almost equal to the high tide
c. the gravitational forces due to the sun and the moon cancel each other's effect
d. the gravitational forces due to the sun and the moon amplify each other's effect

The correct answer is C: the gravitational forces due to the sun and the moon cancel each other's effect.

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.

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
