Weathering
The types of weathering
what are Chemical weathering, and Mechanical weathering?
agents/attributes of erosion
What are water, ice, wind, and gravity?
deposition
What is the placement (staking) of sediments?
Weathering ___________ it
Erosion ________________ it
Deposition _____________ it
What is "breaks, takes & stakes"?
Mechanical weathering where the rock is peeled like an onion
What is exfoliation?
A chemical change in which a substance combines with oxygen, as when iron oxidizes, forming rust
What is oxidation?
Breaks down rocks into sediments
What does weathering do?
moves the sediments that weathering created.
What is Erosion?
ridge formed by rock and soil deposited by a melting glacier
What is a moraine?
Chemical weathering changes the _________________ of the rock
What is composition?
Sedimentary rock
What kind of rock is formed by pressure from deposition of sediment?
Rain containing acids that form in the atmosphere when industrial gas emissions (especially sulfur dioxide and nitrogen oxides) combine with water.
What is acid rain?
agents/attributes of weathering
What are Ice, water, wind?
sinkholes,caves
what are formations made by erosion?
beaches, deltas, and sand dunes
what are formations made by deposition?
Mechanical weathering changes the _______________ of the rock;
What is shape and size?
Igneous Rock
What kind of rock is formed from cooled magma?
Stalactite
What is A deposit that hangs like an icicle from the roof of a cave (acTite =Top)
Biological mechanical weathering
What are Animals and plant roots?
the movement of sediments
what is erosion?
Erosion
what goes before deposition?
The mechanical Process that splits rock when water seeps into cracks, then freezes and expands.
What is frost wedging?
Metamorphic rock
What kind of rock is formed from sedimentary rock through pressure and heat?
Stalagmite
A column-like form that grows upward from the floor of a cavern. (aGmite = Ground)
Acid Rain, oxidation
What are two types of chemical weathering?
Weathering
what does erosion come after
agents/attributes of deposition
What are gravity, ice, water, and wind
Mechanical weathering - upthrust of rock, sediment or soil due to the freezing of water beneath or around it
What is frost heaving?
Wearing away by rubbing and friction
What is abrasion?
the series of processes that change one type of rock into another type of rock
What is the rock cycle?
