Weathering, Erosion, Deposition
Terms in this set (30)
The process by which natural forces break down rocks.
The breakdown of rock into smaller pieces of the same material without any change in its composition.
The breakdown or decomposition of rock that takes place when minerals change through chemical processes.
The process in which layers or sheets of rock gradually break off.
The process of wearing something down by friction.
The process in which sediment is picked up and moved from one place to another.
The process in which transported sediment is laid down.
Downhill movement of loose rock or soil.
Area of land in which water drains into a stream system.
Continuous high line of land- or ridge- from which water drains to one side or the other.
flat area of land on either side of a stream that becomes flooded when a river overflows its banks.
open basin that forms when the roof of a cavern becomes so thin that it falls in.
a long, narrow island that develops parallel to a coast as a sandbar builds up above the water's surface
a mound of sand built up by wind
a large mass of ice that exists year-round and moves over land
a bowl-shaped lake that was formed as a sediment built up around a block of ice left behind by a glacier
a slide of loose debris that moves as a single unit on a hillside
the slowest form of mass movement, occurs when soil closer to the surface moves faster than the soil farther down, which causes fences and poles to lean.
a ridge of sand built up by the action of waves and currents
a mountain slope collapses sending a mixture of rock, soil, and plants downhill
The decayed organic matter in soil.
A soil layer with physical and chemical properties that differ from those of soil layers above or below it.
The expansion of desert conditions in areas where the natural plant cover has been destroyed.
A trace or remains of a once-living thing from long ago.
A fossil that is the actual body or body parts of an organism.
A visible shape that was left after an animal or plant was buried in sediment and decayed.
A solid model in the shape of the organism.
A tree that has been fossilized as stone.
The detailed visible layer, made by carbon, left behind when plants or animals decay.
Evidence of an animal's presence in a given location. Examples: preserved footprints, trails, animal holes, and feces.
