PROCESSES
What process happens when a glacier scrapes rock from the ground?
Abrasion
What glacial landform is a sharp ridge between two corries?
Arête
What do we call a large rock carried and dropped by a glacier?
Erratic
Why do tourists visit glacial landscapes?
Scenery and outdoor activities
What process happens when a glacier pulls rocks away from the ground?
Plucking
What landform is a long narrow lake in a glacial valley?
Ribbon Lake
What landform is a long winding ridge of sand and gravel?
Esker
Why are U-shaped valleys useful for transport routes?
They provide natural routes for roads and railways.
What shape valley is created by glacier erosion?
U
What landform is a smaller valley above a main glacial valley?
Hanging Valley
What is an outwash plain made of?
Sand and gravel deposited by meltwater
How can glacial lakes help generate electricity?
They can be used for hydroelectric power.
Which two processes work together to erode glacial valleys?
Plucking and abrasion
What landform is a deep glacial valley filled with seawater?
Fjord
What type of water flow forms an esker?
Rivers flowing beneath a glacier
Give two negative impacts of glaciation on people.
Poor farming land, flooding, poor drainage.
Explain how plucking and abrasion work together to shape glacial landscapes.
Plucking removes rocks from the ground and abrasion grinds the surface as the glacier moves.
Explain how a ribbon lake forms.
A glacier erodes softer rock more deeply in a valley and when the glacier melts the hollow fills with water.
Explain how an outwash plain forms.
Meltwater flowing from glaciers carries sand and gravel and deposits it in a flat area.
Explain one positive and one negative way glaciation affects people.
Positive – tourism or hydroelectric power.
Negative – poor farmland or flooding.
