Earth Science Test (Part 1)

Front

What are decomposers?

Back

Decomposers are organisms that break down dead plants and animals, returning nutrients to the soil. They fit into the food chain any time there's waste.

Front

What is a Constructive Force?

Back

A Constructive Force is a natural process that builds up landforms, such as when wind slows down and creates sand dunes.

Front

What is a Destructive Force?

Back

A Destructive Force is a natural process that breaks down landforms, such as when the Colorado River weathered the sides of the Grand Canyon.

Front

What is weathering?

Back

Weathering is the process that breaks down rocks and land into smaller pieces.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding the Earth, containing all the gases on the planet.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers recycle nutrients back into the soil, making them available for plants and other organisms.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from one location and transported to another, often by wind or water.

Front

How do sand dunes form?

Back

Sand dunes form when wind picks up sand and deposits it in a new location, creating hills of sand.

Front

What is the hydrosphere?

Back

The hydrosphere includes all the water on Earth, such as oceans, rivers, lakes, and groundwater.

Front

What is the geosphere?

Back

The geosphere is the solid part of the Earth, including rocks, soil, and landforms.
