Hydrology Unit Lesson

every year, the Moon's average distance from Earth increases by about 3.8 centimeters. When the Moon comes to be a much greater distance from Earth, Earth's oceans will experience

• less extreme tides than they do today.

• more extreme tides than they do today.

• tides that are similar as those found today.

• A. tides that are not even noticeable.

When spring hits cold regions, frozen rivers begin to thaw and ice floes can be observed floating down river. Are there ice floes on the bottom of the river?

• No, because ice has a lower density than water.

• No, because ice has a higher density than water.

• Yes, because ice has a lower density than liquid water.

• Yes, because ice has a higher density than liquid water.

• electrical force

• frictional force

• gravitational force

• magnetic force

The moon was created about 4.5 billion years ago when an object the size of Mars crashed into Earth. The crash threw rocks, debris, and dirt into space and these materials came together to form the moon. What would most likely happen if the moon was smaller than it is now?

• The tides would be smaller because the gravitational pull between the Moon and Earth would be smaller.

• The tides would be bigger because the gravitational pull between the Moon and Earth would be smaller.

• The tides would be smaller because the gravitational pull between the Moon and Earth would be bigger.

• The tides would be bigger because the gravitational pull between the Moon and Earth would be bigger.

Which statement best explains how the Moon causes tides?

• A full moon causes high tides, a new moon causes low tides, and other phases of the Moon cause tides that rise and fall.

• The force of the Moon's gravity pulls ocean water along a beach or harbor up into a high tide for a few hours and then lets it drop to low tide.

• The pull of the Moon's gravity causes ocean water to bulge out, and the tidal bulge moves around the world as the Earth rotates and the Moon orbits Earth.

• When the Moon is over an ocean beach or harbor at night, the tide in that place forms a high tide and it forms a low tide when the Moon is not visible during the day.
