Question

1. what causes the high tide on the opposite side of the moon?

wind
centrifugal force
the gravitational pull of the moon
surface tension
ocean currents

Explanation:

To determine the cause of high tide on the moon - opposite side of Earth, we analyze each option:

• Wind: Wind affects surface water movement but not tidal bulges on the opposite side of the moon, so this is incorrect.
• Centrifugal force: The Earth - Moon system rotates around a common center of mass. On the side of Earth opposite the moon, the centrifugal force (a fictitious force in the rotating frame) acting on the Earth's water is greater than the moon's gravitational pull at that point. This causes a tidal bulge (high tide) on that side.
• The gravitational pull of the moon: The moon's gravitational pull is stronger on the side of Earth facing the moon, causing a high tide there. On the opposite side, the pull is weaker, so this is not the cause of the high tide there.
• Surface tension: Surface tension is a property of liquids at interfaces and has no relation to tides, so this is incorrect.
• Ocean currents: Ocean currents are driven by multiple factors like wind, temperature, and salinity, not related to the high tide on the moon - opposite side.

Answer:

B. centrifugal force
