Mass Movement
Erosion & Weathering
Deserts & Soil
Glaciers
Wind
100
Transfer of rock and soil down slope due to GRAVITY
What is Mass Movement
100
thin sheets of water move across a slope picking up soil particles
What is Sheet Erosion
100
A stream that forms after it rains in a Desert
What is Ephemeral Streams
100
Glaciers
What is thick mass of moving ice & snow that forms over hundreds or thousands of years.
100
Deflation and abrasion
what is the two ways deserts erode
200
Rock Falls, Rock Slides, Slump, Flow, Creep
What is The Five Types Of Mass Movement
200
Human activity, Speed of water or wind, Soil characteristics, Climate, Slope, Type of vegetation
What is effects the rate of Erosion
200
Deserts
What is humid regions under strong influence of chemical weathering
200
Valley glaciers, Ice Sheets
What are Two Types of Glaciers
200
is when wind lifts and removes small loose particles of sand
What is Deflation
300
Rock Slides
What is blocks of rock materials moving suddenly along a slope
300
Preserve environments, Protect land, Plant windbreaks, Terrace hillsides, Use contour plowing, Rotate crops
What are the ways to control erosion
300
50% organic and mineral matter and 50% pore space where water and air circulate
What is Good Quality Soil
300
When mass of ice & snow builds up enough pressure, bottom becomes partially melted allowing glacier to move due to gravity
How Do Glaciers Move
300
When wind blown sand cuts and polishes exposed rock
What is Abrasion
400
Flow
What is a mass movement of materials that contain large amount of water
400
physical processes that break rock into smaller pieces without changing their chemical composition
What is Mechanical weathering
400
water and wind
What does erosion in desert comes from
400
sediments picked up with re-freezing glacial ice as glacier moves rock is moved with it
What is Plucking
400
Dunes
What is what can wind deposits create
500
Creep
What is slowest type of mass movement
500
Substances like air and water react with minerals in rock causing it to change in chemical composition
What is Chemical Weathering
500
A,B,C,R
what are the 4 types of soil Horizons
500
ice and rock fragments act like sandpaper smoothing and polishing the surface
What is Abrasion
500
fine windblown silt that blankets the landscape
What is Loess
