Geoscience Processes

Geoscience processes are natural actions that change the Earth's surface over time. These include things like erosion, weathering, earthquakes, and volcanoes. For example, rivers can slowly wear away rocks and soil, carving deep valleys or canyons. Wind can carry sand and shape deserts, while glaciers can move across land, leaving behind deep grooves and valleys. 

Some geoscience processes happen slowly, over millions of years, like mountains forming or rocks breaking down into soil. Others, like earthquakes and volcanic eruptions, happen quickly and can cause big changes in just a few minutes or days. 

These processes show how the Earth is always changing, even if it happens so slowly that we don’t notice it every day. 

Refer to “Geoscience Processes.” How do glaciers change Earth’s surface over long periods?

• By depositing large amounts of volcanic ash.

• By scraping and carving valleys as they move.

• By rapidly melting and flooding valleys.

• By building mountains as they flow.
