Processes of Erosion and Deposition

What is erosion?

• The moving water that deepens the riverbed or erodes laterally into the riverbank.

• The force of moving water.

• The load of the river hitting off the riverbed and banks.

• The rounding of the stones and pebbles carried by the river.

What is hydraulic action?

• The moving water that deepens the riverbed.

• The force of moving water.

• The load of the river hitting off the riverbed.

• The chemical breakdown of rocks.

What is abrasion?

• The moving water that deepens the riverbed.

• The load of the river hitting off the riverbed and banks.

• The rounding of the stones and pebbles carried by the river.

• The chemical breakdown of rocks.

What is attrition?

• The moving water that deepens the riverbed.

• The force of moving water.

• The rounding of the stones and pebbles carried by the river as they knock off each other.

• The chemical breakdown of rocks.

What is solution in the context of erosion?

• The moving water that deepens the riverbed.

• The chemical breakdown of rocks due to acids in the water.

• The load of the river hitting off the riverbed.

• The rounding of the stones and pebbles carried by the river.

What is suspension in the context of transportation?

• Silt and sand in the water that is light enough to be suspended.

• The rocks dissolved due to chemical reactions.

• The materials of rocks and riverbed that are visible.

• The load is heavy and the river rolls and drags the rocks.

What is saltation?

• The rocks dissolved due to chemical reactions.

• Silt and sand in the water that is light enough to be suspended.

• When the materials of rocks and riverbed are visible and slightly heavier.

• The load is heavy and the river rolls and drags the rocks.

What is traction?

• When the load is heavy and the river rolls and drags the rocks along the riverbed.

• The rocks dissolved due to chemical reactions.

• Silt and sand in the water that is light enough to be suspended.

• The materials of rocks and riverbed that are visible.

What factors influence deposition?

• Speed, Volume, Slope, Large Load, Type of Rock

• Erosion, Transportation, Deposition

• Hydraulic Action, Abrasion, Attrition

• Chemical Reactions, Physical Changes

What is a waterfall?

• A feature found in the youthful stage of the river.

• A feature found in the old stage of the river.

• A feature formed from meanders.

• A feature created by human activity.
