| ROCK CYCLE | ||
| #1 | Name the 3 types of rocks formed in the rock cycle |
Igneous, Metamorphic, Sedimentary |
| #2 | 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 |
| #3 | Which type of rock is formed by from the addition of HEAT from magma and great PRESSURE on sediments or existing rocks? |
Metamorphic Rock |
| #4 | 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 |
| #5 | What is the ROCK CYCLE? |
How rocks change into other kinds of rocks |
| WEATHERING-EROSION | ||
| #1 | The breaking of rocks is called___. |
Weathering |
| #2 | The movement of rocks or sediments is called___. |
Erosion |
| #3 | The dropping off of sediments is called__. |
Deposition |
| #4 | 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,... |
| #5 | 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) |
| GLACIERS SHAPE LAND | ||
| #1 | 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. |
| #2 | 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. |
| #3 | 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. |
| #4 | 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. |
| #5 | 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. |
| SOIL | ||
| #1 | What makes up soil?hint-3 basic parts |
A mixture of sediments, decomposing organic material, and microorganisms. |
| #2 | Give 2 examples of decomposing organic material. |
dead plants (leaves, sticks, wood), dead animals, manure |
| #3 | Give 2 examples of microrganisms in soil. |
Worms, bacteria, nematodes, ... |
| #4 | What non-living (inorganic) materials are found in soil? |
Air, water, minerals, rock sediments |
| #5 | 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) |
| PARTICLES OF ROCK | ||
| #1 | ____________________ make up rocks. |
Minerals make up rocks |
| #2 | Why do some rocks have different colors or luster than other rocks? |
Rocks are a mixture of minerals. |
| #3 | Pieces of broken rock created during the process of weathering and erosion are called__. |
Sediments |
| #4 | Name the 4 sediments that were observed in class in order from biggest to smallest. |
Gravel, sand, silt, clay |
| #5 | Which sediment will drain water the quickest? Which sediment will drain water the slowest? |
Quickest- Gravel Slowest- clay |
