IGCSE Geography- Rivers

When the roots of plants grow in the cracks of a rock and splits it, we call it...

• Biological Weathering

• Physical Weathering

• Solution

• Soil Creep

What is it called when water is forced into cracks in the bed and pressure expands the cracks further

• Suspension

• Hydraulic Action

• Attrition

• Solution

soluble material dissolved in river water and transported downstream

• Suspension

• Multipoint

• Solution

• Traction

Water Pollution from farms can lead to (more than one choice)

• Fertilizer Leaching

• Coral Bleaching

• Eutrophication

• Increased Bacteria growth and Deoxygenation

The breaking down or dissolving of rocks in site

• Weathering

• Precipitation

• Erosion

• Slumping

fine loads of sediment being carried along by the river flow

• Solution

• Revocation

• Expiration

• Suspension

the flow of water between ground surface and the top of ground water store, moves slowly under the influence of gravity until it reaches a body of water

• stem flow

• groundwater flow

• 
  through flow

• drainage basin

Dams, Levees, Channelization, and Flood barriers are examples of..

• Hard Engineering

• Soft Engineering

Small material bounces in small hops along the river bed

• Suspension

• Deposition

• Traction

• Saltation

Weathering cased by acid rain, causing decay

• virtual water

• solution

• physical weathering

• chemical weathering
