Weathering & Erosion
What does weathering do to a rock?
What is “breaking down a rock”
What does deposition do to rocks?
What is “drop sediments”
What is mechanical weathering?
What is “mechanical weathering breaks up rock into smaller pieces”
The process by which water, ice, wind, or gravity moves weathered particles of rock and soil.
What is “till”
What does erosion do to a rock?
What is “moves the rock to a new location”
What does deposition drop?
What is “loose pieces of rocks”
What is chemical weathering?
What is “the erosion of of rocks that occurs because of chemical reactions”
Water the flows over the ground surface rather than soaking into the ground.
What is “runoff”
What are the 4 main causes for erosion?
What is “water, wind, ice, or gravity”
What is the definition of deposition?
What is “the laying down of sediment carried by wind, flowing water, the sea or ice”
What an example of chemical weathering?
What is “rust, which happens through oxidation and acid rain, caused from carbonic acid dissolves rocks”
A landform made of sediment that is deposited where a river flows into an ocean or a lake.
What is “delta”
What are the 2 main types of erosion?
What is “chemical and physical”
What causes deposition?
What is “when the eroding agent, whether it’s gravity, ice, water, waves, or wind, runs out of energy and can no longer carry its load of eroded material”
What’s an example of mechanical weathering?
What is “exfoliation, water and salt crystal expansion, thermal expansion, abrasion by wind and water erosion, and even some types of actions by living things (like plant roots or a burrowing mole)”
The process by which a glacier picks up rocks as it flows over land.
What is “plucking”
What is the most powerful force of erosion?
What is “water”
What’s an example of deposition?
What is “deposition is the transition of a substance directly from the gas to the solid state on cooling, without passing through the liquid state”
What is the difference between chemical and mechanical weathering?
What is “Mechanical weathering breaks rocks into smaller pieces without changing their composition. Ice wedging and abrasion are two important processes of mechanical weathering. Chemical weathering breaks down rocks by forming new minerals that are stable at the Earth's surface”
The geologic principle that the same geologic processes that change Earths surface.
What is “uniformitarianism”
