Transport and sedimentation

Lesson goals

1. Review tranport and sedimentation

Weathering is the break down of hard rock. The two types are ...... and ........ weathering

1. physical - eroded
2. physical - mechanical
3. chemical - non chemical
4. mechanical - chemical

Circumstances in which chemical weathering occurs

1. hot and humid climate
2. large temperature amplitude
3. hot and dry climate
4. Extremely cold winters

Circumstances in which mechanical weathering may occur.

1. Mediterranean climate
2. Hot and humid climate
3. Extreme temperature differences
4. A moderate maritime climate

Rivers 

Sedimentation and Erosion.

Erosion = Weathering and transport

Sedimentation = the deposition of eroded material

01:40

In the outer bend of the river the water flows ........... and there is a lot of ...............

1. slow - erosion
2. slow - sedimentation
3. fast - sedimentation
4. fast - erosion

Deposition

The glacier makes a U-shaped valley

The glacier brought rocks from Scandinavia to The Netherlands

The glacier picks up rocks

The glacier melts and leaves rocks behind

Rocks in the glacier scrapes away rocks below the glacier

The glacier moves and there are rocks inside the glacier
