Front

What is the difference between high tide and low tide?

Back

High tide is the maximum level of ocean water, while low tide is the minimum level of ocean water.

Front

What is the effect of the sun on tides?

Back

The sun's gravitational pull also affects tides, but its effect is less than that of the moon.

Front
