Constructive Process
Deposition
Process in which sediment is laid down in new locations. *Deposited dropped off
*Erosion first then deposition.
Erosion
The movement of sediment from one location to another.
*Erosion is more of the loosening and movement of the sediment to somewhere where deposition can then take it. Erosion first then deposition.
Physical Weathering
Mechanical Breakdown of rocks and minerals
Chemical Weathering
The process that breaks down rocks through chemical changes.
Abrasion Weathering
Types of mechanical weathering that occurs when rocks are grinded away by friction or impact.
-Wind
-Water
-Ice
Thermal Expansion Weathering
Rapid temperatures, such as day and night cycles, can cause the rocks to expand and contract leading to cracks and fragments in the rocks.
Frost Wedging Weathering
Liquid water enters cracks, before then freezing leading the ice to expand forcing the rock to break apart.
Salt Crystal Growth Weathering
Salt water is absorbed then evaporates which then leaves crystallized salt which pushes the rocks apart.
Biological Activity/Root Wedging Weathering
Living organisms cause weathering
-Burrowing animals
-Roots from plants
Oxidation
Chemical Weathering that occurs when oxygen combines with another substance (usually iron) to make a new substance.
Carbonization Weathering
Water and carbon dioxide combine to make carbonic acid, which eats away at rocks and limestone. Leads to the creation of caves.
Acid Precipitation (Acid Rain)
Rain mixes with sulfuric acid and nitrogen oxide to make a weak acid that eats away at rocks.
Hydrosis
The breaking down of complex molecules by the chemical addition of water.
-Makes clay and soluble salts.
Mountain
A natural elevation of the earth’s surface rising abruptly from surrounding levels created by tectonic plates crashing into one each other.
Dune
Made by a pile of sand deposited by wind.
Plain
A large flat area of land created by deposition of sediments from elsewhere.
Hill
They are created by water erosion of mountains or the melting and shifting of glaciers.
Volcano
Created by magma rising from hot spots and as lava erupts through cracks in the Earth’s Surface.
Caves
Forms from carbon dioxide mixing with water to create carbonic acid that eats away at limestone.
Delta
Wetlands that form as rivers empty their waters and sediments into another body of water.
Plateau
Level large expanse of land that rises 1500ft or move above the surrounding land with at least one steep side.
-Created by wind and water erosion.
Valley
Created by running rivers and glacial movements.
-Low area between mountains is where they are located.
Canyon
Deep and narrow valleys with steep walls typically made by a river.
Constructive Process
The process by which landforms are created by materials being brought to them.
Destructive Process
The process by which landforms are created by materials being taken away from an area.
Drumlin
A long mound of till that is smoothed in the direction of the glaciers flow
Moraine
A ridge formed by till deposited at the edge of a glacier.
The San Andreas Fault is an example of what type of plate boundary?
