Erosion/Deposition released items

Students build a stream table model as shown to observe processes and rates of erosion. They place one end of the stream table on blocks to change the slope of the stream. They also change the height of the water source by adding or removing blocks beneath the water source.

Identify if the following changes would increase or decrease erosion.

Groups:

(a) Increase erosion

,

(b) Decrease Erosion

• Planting grass in the sediment.

• Removing a block from beneath the stream table.

• Increasing diameter of the drainage hole.

• Adding another block below the water source.

The diagram shows the direction of ocean waves as they approach a bay.

Which geologic process directly forms beaches on the shores of the bay.

• tectonic rifting

• glacial advance

• volcanic activity

• sediment deposition

Which statement describes how rock characteristics affect rates of weathering?

• Rocks with metamorphic rock weather more quickly than sedimentary rock.

• Rocks with gaps & cracks weather more quickly than rocks with smooth surfaces.

• Rocks without minerals weather more quickly than rocks made up of many minerals.

• Rocks that are buried deep underground weather more quickly than rocks at the surface.

Bryce Canyon National Park in Utah is famous for having many formations called hoodoos. Hoodoos are tall structured made of sedimentary rock. The Hoodoo Formation diagram shows the processes that create these unique rock structures.

Select the two main geological processes that create the hoodoos.

• erosion

• deposition

• weathering

• volcanic activity

• tectonic movement
