Flashcard #2.4 - Exogenic Process

Front

The natural chemical or physical processes that breaks down rock on Earth's surface.

Back

weathering

Front

The process by which water, ice, wind or gravity moves weathered rock and soil from one place to another.

Back

erosion

Front

This type of weathering occurs when rock is physically broken down into smaller pieces of rock.

Back

mechanical weathering

Front

This type of weathering occurs when rocks weaken then break down due to chemical changes in the composition of the rock.

Back

chemical weathering

Front

These rocks were made smooth by wind blowing smaller rock particles across their surface. This is an example of:

Back

abrasion

Front

These rocks were broken apart from the continuous freeze/thaw of water in the cracks of the rocks. This is an example of: ice wedging, acid rain, permeability, abrasion

Back

ice wedging

Front

This rock may chemically weather easily because it has many spaces or holes in it that allow water to seep through it, meaning it is:

Back

permeable

Front

What causes gravestones to slowly break down and turn a blackish color?

Back

acid rain

Front

How might a weathered mountain appear different than an unweathered mountain?

Back

Weathered mountain would be rounder and less jagged.

Front

How is mechanical weathering different from chemical weathering?

Back

Chemical weathering changes the chemical composition of rocks; mechanical weathering does not.
