Q.1
Rivers are one of the most powerful forces of erosion on land. What are the four main types of river erosion?
  • Hydraulic, attrition, traction and saltation
  • Solution, suspension, saltation and traction
  • Hydraulic, abrasion, attrition and solution
  • Solution, suspension, attrition and abrasion
Q.2
Which of the following is a method by which deforestation increases erosion?
  • Trees and forests may encourage large scale tourism
  • Trees no longer take up water, increasing run off and through flow
  • Trees are no longer able to stabilize river banks leading to uncontrolled meandering
  • Tree roots no longer stabilize and protect the soil, leading it to be washed away
Q.3
When river velocity slows the larger particles fall out of suspension. Which of these examples shows when velocity may drop leading to silting up of a part of the river?
  • The outside of a meander bend
  • Where a narrow river channel enters an open lake
  • When water runs over rapids
  • The entrance to an artificially straightened channel
Q.4
What type of coastal wave causes erosion?
  • Constructive
  • Destructive
  • Swash
  • Backwash
Q.5
Which of the following is a way that climate change will increase erosion?
  • Due to warmer conditions trees and other plants may be able to grow further north
  • Rising sea levels will allow waves to attack new areas of beaches and cliffs
  • Increased rainfall will lead to greater erosion by rivers
  • More extreme weather conditions, such as hurricanes, will lead to greater force of waves and wind on the coastal areas
Q.6
Weathering and erosion are a key part of the rock cycle. Which class of rocks are formed after weathering and erosion have attacked other rocks?
  • Sedimentary
  • Igneous
  • Metamorphic
  • Oolitic
Q.7
Some rocks show that a glacier has eroded them by scratch marks across their faces. What are these scratches known as?
  • Pluck marks
  • Striations
  • Abrasions
  • Névé
Q.8
Which are the four main types of river transportation of eroded material?
  • Hydraulic, abrasion, attrition and solution
  • Hydraulic, attrition, traction and saltation
  • Solution, suspension, attrition and abrasion
  • Solution, suspension, saltation and traction
Q.9
Glaciers carve out landforms as they move across the landscape. What is the valley shape that is commonly cut by a glacier?
  • U-shaped
  • V-shaped
  • Truncated
  • Braided
Q.10
South Stack in Anglesey is an example of a stack - a type of coastal erosional landform. What was this landform before it was eroded to form a stack?
  • A stump
  • An arch
  • A cave
  • A wave cut platform
