Weathering Erosion And Deposition Flashcards
Freezing and thawing, temperature, and living organisms are examples of what type of weathering
Mechanical or physical
What is the movement of sediment called
Erosion
What is it called when sediment is laid down in new locations
Deposition
What happens to the rate of chemical weathering in a warm humid climate
Increase
Oxidation carbonation and hydrolysis are examples of what type of weathering
Chemical
What is the major agent of erosion and weathering on earth
Water
If an area loses material quickly is it more or less resistant to weathering
Less
Why does sediment weather faster then large rocks
It has more surface area
Freezing or thawing
Freezing - freezes
Thawing - melts
Temperature
Hot- expansion in rocks
Cool- rocks contract
Living organism
Plant roots- go down for nuitrence and water and act as a wedge
Animal burrowing
Oxidation
Oxygen combines with other elements in rocks to make new ones
Hydrolysis
Water combines with substances in rocks to form new soft substances
Carbonation
Carbon dioxide reacts to certain rocks forming a solution that can be carried away by water
When does erosion occurs
Running water picks up rocks and sediment and moves them from one location to another
What is sandblasting
When particles and sand wear off
How is sand made
The gradual process of breaking down pebbles
Wind
The wind picks up light objects like sands and hurls it at landforms breaking off pieces
Glacier
Moves slowly but it covers vast expanses feeling and transporting bits of rock
Waves
Waves move toward and away from the shoreline carrying sediment away and too the shoreline
Water
Currents carry off sediments collected from the streams bed and banks
What is breaking down if earths materials called
