Mechanical weathering

Chemical weathering

Drag the right term to the right image

Chemical weathering

Mechanical weathering: frostweathering

Mechanical weathering: differences in temperature 

Mechanical weathering by plants/trees

Mass movement

Rock moving down a slope due to gravity.

Mass Movements

Creeping - Fast & Wet - Dry

Part 2

Erosion

During transport by wind, water and ice, erosion takes place

Erosion = the process by which the surface of the earth is worn away by the action of water, glaciers, winds, waves, etc.

What kind of erosion caused
the rock in the photo?

1. River
2. Wind
3. Glacier
4. Sea/waves

Erosion affects, among other things, stones

Weathering and erosion cause the solid rock to fall apart further and further

Set the soil types from coarse (big) to fine (small)

Effects of erosion

Take a look at the appearance of the valleys.

What differences do you see?

Which characteristics
match the valley in
the picture?

1. Rivervalley, V-shaped
2. Rivervalley, U-shaped
3. Glacial valley, V-shaped
4. Glacial valley, U-shaped
