Earth Science Flashcards
Geologic processes
Events that occur over and over again through out earth history to change the surface of the earth
Weathering
Breaking up or dissolving of rock and soil into pieces
Erosion
The caring away (movement) of rock and soil creates holes
Deposition
Is the dropping of dirt,eroded rock and soil in piles in a new location
Layers of earth
Crust-thin and brittles
Mantle-think liquid (think liquid)
Outer-liquid,mealted rocks
Inner core-solid
Convection currents
A temperature difference within a fluid causes hotter fluid to rise and colder fluid to sink.This causes earth plates to move=plate tectonics
Plate tectonics
A gedoical theory that states that pieces of the earth crust are in constant slow motion
Continental drift
Means moving continents drift the climate many change
