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 answer for the question above is A. the gravitational pull of the moon on the water near the coast. The sun and and the moon are responsible for the rising and falling of the ocean tides. The gravitational pull of the moon and the sun makes the water in the oceans bulge, causing a continuous change between high and low tide.
