Rockin' & Rollin'
These are the three categories of rock.
What are sedimentary, igneous, & metamorphic?
Water in the pores of the rock freezes and expands during the winter, acting like a wedge and forcing the rock apart.
What is frost wedging?
A stronger acid solution resulting from pollution in the atmosphere
What is acid rain?
Loose material at the surface of the earth
What is soil?
The primary force behind erosion
What is gravity?
This type of cave is created by chemical weathering
What is a limestone cave?
A shift in the ground around rocks that reduces pressure and causes the rocks to expand rapidly.
What is pressure release?
Two types of chemical weathering
What are oxidation and reaction of acids with minerals in the rocks?
Soil particles mixed with water, air, and decayed organic matter
What is humus?
Other factors of erosion, including water, wind, and ice
What are agents of erosion?
This transforms rocks into new substances
What is chemical weathering?
Water freezing underneath a rock & pushing it up out of the ground.
What is frost heaving?
When carbon dioxide in the earth’s atmosphere dissolves in water, creating a weak acid
What is carbonic acid?
The largest kind of particle
What is sand?
When gravity is the primary force that moves rocks and sediments
What is mass movement?
This breaks rocks into smaller and smaller pieces
What is mechanical weathering?
Mechanical weathering that occurs when rocks rub against each other.
What is abrasion?
A small particle that allows water and air to mix in soil
what is silt?
When all 3 kinds of particles are equally evident in the soil
The sediment that a stream carries
What is a load?
These are beautiful formations in caverns formed by dissolved calcite deposits in the water
What are speleothems?
Sheet rock peel away like layers of an onion
What is exfoliation?
The multiple layers of soil
horizons
Tells how much of each kind of particle is in the soil sample
What is Soil Texture?
Deposit of soil and rock from a melted glacier
What is a moraine?
