1. Kaleigh notices when she goes to the beach that sometimes the water rises as high as the pier. At other times of the day, the water barely covers the pillars under the pier. These differences in water level are primarily due to the gravitational influence of which of the following?
a. The Earth’s revolution b. The Moon c. asteroids d. comets

Respuesta :

B. The moon
Tides are due to the gravitational forces of the Moon and the Sun. The tide is high when the moon or the sun or both are on the side of the sea and vice versa.
The effect of tides due to the moon is much greater than that of the sun, because the moon is much closer to the earth.
