Earth Science Flashcard

Front

What are fossils?

Back

Fossils are the remains or impressions of plants or animals that existed millions of years ago.

Front

What causes erosion?

Back

Erosion can be caused by water, wind, and glaciers.

Front

What are sedimentary rocks?

Back

Sedimentary rocks are formed from weathering and erosion when sediments are compressed and cemented together.

Front

How can wind shape rock formations?

Back

Wind-blown sand can carve away at big rocks, creating unique rock formations over millions of years.

Front

What is a metaphor for erosion?

Back

Erosion is like a broom sweeping pieces away.

Front

What is the process of weathering?

Back

Weathering is the breaking down of rocks into smaller pieces by natural forces like wind, water, and temperature changes.

Front

What are igneous rocks?

Back

Igneous rocks are formed from the cooling and solidification of molten rock (magma or lava).

Front

What are metamorphic rocks?

Back

Metamorphic rocks are formed when existing rocks are changed by heat, pressure, or chemical processes.

Front

What is the water cycle?

Back

The water cycle is the continuous movement of water on, above, and below the surface of the Earth.

Front

What is the role of glaciers in erosion?

Back

Glaciers can erode land by moving large amounts of rock and soil as they advance and retreat.
