What features does water erosion create?
It makes rocks more smooth, it also moves them around and moves sand around to break down more rocks.
Give an example of wind deposition.
sand dunes
True or False: Chemical weathering occurs when rock is changed to a new substance as a result of interaction between elements
True
What is a passive margin?
a margin that has stopped moving or forming.
How does waves of an ocean affect the physical aspect of a mountain over time?
After a long period of time, the sides of the mountain will start to wither or fade down due to the constant waves rubbing against it, pulling rocks down with the water.
How does a glacier affect the physical aspect of land?
moves sediment and rock and pushes down on the land beneath.
What is a good example of chemical weathering?
rusting, pitting, dissolving
True or False: Pressure outside of the earth are internal forces.
False
What are three land forms made by rivers?
River valleys, waterfalls, structural benches, river terraces, river meanders, ox-bow lakes and peneplains.
True or false: sand dunes are formed by weathering but not by erosion by wind.
false
How does chemical weathering affect soil?
Controls the formation and evolution of soil.
What are the major two external factors for surface rock weathering?
rainfall and temperature
When waves strike rock along a coastline, they erode the base of the rock and continue to erode over time they form what?
sea caves
Why do glaciers form U shaped valleys?
Because they pick up all loose sediment and create a surface with the same shape as the glacier
What is the main cause of chemical weathering?
acid that comes from rainfall
What is an example of an internal force in terms of weathering?
volcanoes, earthquake, plate tectonics
This area of land is usually submerged under a shallow body of water sometimes caused by waves weathering that area below sea level.
continental shelf
What are the piles of rock left by a melting glacier?
moraines
What are three factors that affect the type of drainage (and chemical weathering) of an area?
Regional topography
Shape of the land
Underlying soil or rock
What are the 5 types of internal forces?
Compression, tension, shear, bending and torsion.
