Name the 3 types of rocks formed in the rock cycle

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 from the addition of HEAT from magma and great PRESSURE on sediments or existing rocks?

Which type of rock is formed from rock that has been melted into lava or magma and cools/hardens into solid rock again?

What is the ROCK CYCLE?

The breaking of rocks is called___.

The movement of rocks or sediments is called___.

The dropping off of sediments is called__.

Breaking down rocks into sediments by physical motion is called________ weathering.

Give 2 examples of this.

Breaking down rocks into sediments by chemicals is called________ weathering.

Give 2 examples of this

How do glaciers change the shape of the land by weathering?

Descirbe how a glacier causes erosion.

How does a glacier cause deposition?

How does a glacier change the shape (look) of the land with deposition?

How does a glacier change the shape (look) of the land by erosion?

What makes up soil?hint-3 basic parts

Give 2 examples of decomposing organic material.

Give 2 examples of microrganisms in soil.

What non-living (inorganic) materials are found in soil?

How would soil mixed with lots of clay be different than soil mixed with lots of sand?

____________________ make up rocks.

Why do some rocks have different colors or luster than other rocks?

Pieces of broken rock created during the process of weathering and erosion are called__.

Name the 4 sediments that were observed in class in order from biggest to smallest.

Which sediment will drain water the quickest? Which sediment will drain water the slowest?

Igneous, Metamorphic, Sedimentary

Sedimentary rocks

Metamorphic Rock

Igneous Rock

How rocks change into other kinds of rocks

Weathering

Erosion

Deposition

Physical weathering EX: rain, moving water (waves), glaciers, wind, ice, freeze/thaw, heating/cooling, lightning, plant roots, animal activity,...

Chemical weathering EX- Iron rusting/oxidation, acids (acidic rain), CO2 in water, water, lichens (release acids)

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.

A glacier causes erosion when it moves because sediments are frozen into the ice of the glacier and carried along as it moves.

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. 

The glacier can deposit large amounts sediments or boulders as it moves or melts.  This leaves behind piles of rocks/boulders/builds up hills.

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.

A mixture of sediments, decomposing organic material, and microorganisms.

dead plants (leaves, sticks, wood), dead animals, manure

Worms, bacteria, nematodes, ...

Air, water, minerals, rock sediments

Clay would hold more water (not drain well), may stick together (not be as loose)

Minerals make up rocks

Rocks are a mixture of minerals.

Sediments

Gravel, sand, silt, clay

Quickest- Gravel  Slowest- clay
