C-Science: Weathering And Erosion

Front 1

chemical weathering

Back 1

the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes

Front 2

ice wedging

Back 2

a type of mechanical weathering in which water seeps into the cracks in a rock, freezes and expands, and splits the rock apart

Front 3

lichen

Back 3

a simple slow-growing plant that typically forms a low crustlike, leaflike, or branching growth on rocks, walls, and trees, occurs when an algae and fungus grow together

Front 4

mechanical weathering

Back 4

any of the various weathering processes that cause physical disintegration of exposed rock without any change in the chemical composition of the rock

Front 5

weathering

Back 5

the breakdown of rocks by physical or chemical processes

Front 6

agent

Back 6

a force or material that causes change

Front 7

deposition

Back 7

the process by which rock and soil particles move from water, wind, or ice onto the land

Front 8

erosion

Back 8

the gradual removal of the surface of the land by water, wind or glaciers

Front 9

glacier

Back 9

large moving masses of ice and snow on land

Front 10

mass wasting

Back 10

the downhill movement of rock and soil, also known as mass movement

Front 11

meander

Back 11

a turn or winding of a stream or river, rivers flowing over gently sloping ground begin to curve back and forth across the landscape

Front 12

rivulet

Back 12

a small stream, often flows into a larger stream
