Which of the following can explain the daily change in sea level observed along a coast? a. the gravitational pull of the moon on the water near the coast b. the speed of the ocean's conveyor belt near the coast c. earthquakes and volcanoes near the coast d. the concentration of salt in the water near the coast

The gravitational pull of the moon on the water near the coast (option A) can explain the daily change in sea level observed along a coast.

Explanation:

The tides are rising and falling from sea level that occur several times a day. These periodic changes in the level of the sea are produced by the gravitational forces of attraction of the Sun and the Moon with respect to the Earth. But the force of attraction of the Moon is greater than that of the Sun, due to the proximity of the satellite.

High tide or high tide is the time when the sea reaches its maximum height. Low tide or low tide is the time when the sea reaches its minimum height.

The tide is noticed on the beaches because the coastline can go forward or backward many meters.

Finally, the gravitational pull of the moon on the water near the coast (option A) can explain the daily change in sea level observed along a coast.
