Earth Science Flashcard

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow.

Front

What is the rock cycle?

Back

The rock cycle is the continuous process by which rocks are created, changed, destroyed, and reformed over time.

Front

What does it mean if an organism is extinct?

Back

If an organism is extinct, it means that it no longer exists anywhere on Earth.

Front

What causes flooding?

Back

Flooding can be caused by a large amount of precipitation, such as heavy rain or melting snow.

Front

How does wind contribute to erosion?

Back

Wind can carry small particles of sand and dust, which can wear away rocks and soil over time.

Front

What is weathering?

Back

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

Front

What role do glaciers play in shaping the landscape?

Back

Glaciers can push and carve out rocks and landforms as they move, creating valleys and other geological features.

Front

What is sediment?

Back

Sediment is small particles of rock, soil, and organic material that are transported by wind, water, or ice.

Front

How do ocean waves affect shorelines?

Back

Ocean waves can erode rocks and sand on the shore, reshaping the coastline over time.

Front

What is the difference between igneous, sedimentary, and metamorphic rocks?

Back

Igneous rocks form from cooled magma, sedimentary rocks form from compressed sediments, and metamorphic rocks form from existing rocks that have been changed by heat and pressure.
