2.1 Notes Flashcards
A large mass of ice, formed by snow accumulation on land, that moves slowly across Earth’s surface.
Glacier
The moving of weathered material, or sediment from one location to another is called.
Erosion
Chemical weathering happens fastest in the presence of.
Water
Weathering breaks apart rocks by physical processes.
Mechanical
Erosion occurs where moving river water picks up soil and moves it downstream
Fast
Deposition occurs where a river current as it enters a larger body of water and the soil.
Slows,deposits
Ice and plant roots are weathering agents because they within cracks in rock to break the rock apart.
Expand
What type of erosion most likely occurs in deserts?
Wind
The movement of larger sediment by wind erosion requires what two factors to change?
Strength & Time
A is a naturally occurring, inorganic solid that has a crystal structure and a definite chemical composition.
Mineral
Igneous rocks form from and when it cools.
Magma & Lava
Igneous rock that forms when volcanic material erupts, cools, and crystallizes on Earth’s surface is called rock.
Extrusive rock
Sedimentary rocks are changed to sediments by and
Weathering & Erosion
The crystals that form in slowly cooled magma produce mineral grains.
Coarse
Rocks can change throughout many different processes including weathering, deposition, melting, and compaction. All of these change rock on Earth’s surface except
Melting
