Changing Land Review

What word means 'all objects that have biological processes that keep them alive, such as plants and animals'?

• living things

• soil

• rainfall

• gravity

A student was observing rocks he found at a riverbed. The rocks he found were smooth and rounded because the rocks–

• were part of a glacier that melted.

• were formed from lava during an earthquake.

• rolled down the side of a mountain.

• were in a river that had fast-moving water.

What happens to a shoreline as waves crash into it?

• Sand is added to create dunes.

• Sediment is only deposited.

• The shoreline gets larger.

• Sand is washed away.

When particles or sediment are picked up and carried away by wind, water, or ice, what has occurred?

• deposition

• evaporation

• erosion

• weathering

Which word means 'the smallest possible piece of something?"

• region

• particles

• weathering

• rainfall

What are sediments?

• Sand or small pieces of rock broken down by weathering and deposited on the land or at the bottom of a body of water

• Amount of precipitation

• All the plants found in a particular area

• A force that causes objects with mass to attract each other

Deposition occurs when...

• features such as mountains, hills, oceans, and rivers are created on Earth's surface.

• wind, water, and ice move weathered material down a mountainside.

• rock is broken into smaller particles from the effects of wind, water, and ice.

• sediments build up in one place as a result of the effects of wind, water, and ice on land.

What is Gravity?

• A portion of Earth's surface with borders

• A force that causes objects with mass to attract each other

• A living thing

• Sand or small pieces of rock broken down by weathering and deposited on the land or at the bottom of a body of water

What is soil?

• The gradual wearing down of something by wind, water, and other natural forces

• Mixture of sand, silt, clay, rock, and humus (plant and animal remains)

• A force that causes objects with mass to attract each other

• Sand or small pieces of rock broken down by weathering and deposited on the land or at the bottom of a body of water
