Name two agents of physical or mechanical weathering
Animal Actions, freezing and thawing (frost wedging), plant growth, release of pressure, abrasionName two agents of physical or mechanical weathering
100
What type of valley is created by rivers?
V-shaped valley
100
What causes glaciers to move?
gravity
100
Explain the difference between weathering and erosion
Weather is the breaking down of rock while erosion is weathering but also includes the REMOVAL of the particle
100
What are two ways that waves erode the land?
Impact and abrasion
200
Name two agents of chemical weathering
Oxygen (oxidation), carbon dioxide (carbonic acid), living organisms (plant roots producing acids), acid rain (burning of coal, oil and gas which produces sulfur, carbon and nitrogen)Name two agents of chemical weathering
200
Name two features of river deposition
alluvial fan, delta
200
What are the two processes by which glaciers erode?
abrasion and plucking
200
what is the process by which wind removes surface sediment?
deflation
200
The process by which beach sediment moves down the beach with the current is called
Long shore drift
300
Explain how surface area affects the rate of weathering
Increase surface area, increase the rate of weathering
300
Name three features of river erosion
valleys, waterfalls, flood plains, meanders, oxbow lakes
300
Name three features of glacial erosion
horn, cirque, u-shaped valley, areteName three features of glacial erosion
300
What causes sediment to be deposited by any agent of erosion?
Reduction in velocity (ie. river speed slows)
300
Name three landforms created by beach erosion
wave-cut cliff, sea cave, headland, sea stack, sea arch
400
Chemical weathering increases in what type of environment?
warm and wet
400
Name five factors that affect runoff
amount of vegetation, amount of rain, soil type, shape of the land, human use
400
Name three features of glacial deposition
drumlin, kettle, moraine
400
Describe the difference between sand dunes and loess deposits
Sand dunes have coarser sediments (sand sized) while loess have finer sediments (silt/clay)
400
Name three land forms created by wave deposition
beach, spit, sandbar, barrier beach
500
What are the two factors that determine the rate at which a rock will weather?
rock type and climate
500
Explain how rates of erosion and deposition differ on a meander and why
Erosion occurs on the outside of the meander because here the water moves more quickly compared to the inside where deposition occurs due to decrease in velocityExplain how rates of erosion and deposition differ on a meander and why
500
Name and describe the difference between the two types of glaciers that we learned about
Continental-covers large areas of land, sheet like, moves out in all directions Valley-long, narrow, occurs between mountains, moves downward
500
The shape of sand dunes is determined by what three factors
direction of the wind, amount of sand, presences of plants
500
Under what conditions would you expect abrasion to cause the most erosion on a beach?
In a storm when the waves are stronger and more frequent
