Name the 3 types of rocks formed in the rock cycle
Igneous, Metamorphic, Sedimentary
Which type of rock is formed by sediments that pile up over time and form layers under great pressure and the bottom layers are pressed together?
Which type of rock is formed by sediments that pile up over time and form layers under great pressure and the bottom layers are pressed together?
Sedimentary rocks
Which type of rock is formed by from the addition of HEAT from magma and great PRESSURE on sediments or existing rocks?
Which type of rock is formed by from the addition of HEAT from magma and great PRESSURE on sediments or existing rocks?
Metamorphic Rock
Which type of rock is formed from rock that has been melted into lava or magma and cools/hardens into solid rock again?
Which type of rock is formed from rock that has been melted into lava or magma and cools/hardens into solid rock again?
Igneous Rock
What is the ROCK CYCLE?
What is the ROCK CYCLE?
How rocks change into other kinds of rocks
The breaking of rocks is called___.
The breaking of rocks is called___.
Weathering
The movement of rocks or sediments is called___.
The movement of rocks or sediments is called___.
Erosion
The dropping off of sediments is called__.
The dropping off of sediments is called__.
Deposition
Breaking down rocks into sediments by physical motion is called________ weathering.
Give 2 examples of this.
Breaking down rocks into sediments by physical motion is called________ weathering.
Give 2 examples of this.
Physical weathering EX: rain, moving water (waves), glaciers, wind, ice, freeze/thaw, heating/cooling, lightning, plant roots, animal activity,...
Breaking down rocks into sediments by chemicals is called________ weathering.
Give 2 examples of this
Breaking down rocks into sediments by chemicals is called________ weathering.
Give 2 examples of this
Chemical weathering EX- Iron rusting/oxidation, acids (acidic rain), CO2 in water, water, lichens (release acids)
How do glaciers change the shape of the land by weathering?
How do glaciers change the shape of the land by weathering?
Glaciers have sediments frozen into them. As the glaciers move, their weight grinds the sediments into the land below this breaks rocks and scratches/polishes the land.
Descirbe how a glacier causes erosion.
Descirbe how a glacier causes erosion.
A glacier causes erosion when it moves because sediments are frozen into the ice of the glacier and carried along as it moves.
How does a glacier cause deposition?
How does a glacier cause deposition?
A glacier changes the shape of the land by deposition because when it melts or moves sedminents or rocks can break loose and get deposited.
How does a glacier change the shape (look) of the land with deposition?
How does a glacier change the shape (look) of the land with deposition?
The glacier can deposit large amounts sediments or boulders as it moves or melts. This leaves behind piles of rocks/boulders/builds up hills.
How does a glacier change the shape (look) of the land by erosion?
How does a glacier change the shape (look) of the land by erosion?
A glacier changes the shape look of the land by moving/carrying large amounts of sedminents. This can create valleys, lakes, ponds, horns, aretes, cirques, or polished rocks.
What makes up soil?hint-3 basic parts
What makes up soil?hint-3 basic parts
A mixture of sediments, decomposing organic material, and microorganisms.
Give 2 examples of decomposing organic material.
Give 2 examples of decomposing organic material.
dead plants (leaves, sticks, wood), dead animals, manure
Give 2 examples of microrganisms in soil.
Give 2 examples of microrganisms in soil.
Worms, bacteria, nematodes, ...
What non-living (inorganic) materials are found in soil?
What non-living (inorganic) materials are found in soil?
Air, water, minerals, rock sediments
How would soil mixed with lots of clay be different than soil mixed with lots of sand?
How would soil mixed with lots of clay be different than soil mixed with lots of sand?
Clay would hold more water (not drain well), may stick together (not be as loose)
____________________ make up rocks.
____________________ make up rocks.
Minerals make up rocks
Why do some rocks have different colors or luster than other rocks?
Why do some rocks have different colors or luster than other rocks?
Rocks are a mixture of minerals.
Pieces of broken rock created during the process of weathering and erosion are called__.
Pieces of broken rock created during the process of weathering and erosion are called__.
Sediments
Name the 4 sediments that were observed in class in order from biggest to smallest.

Quickest- Gravel Slowest- clay
