Rocks and Minerals Study Guide
Test is Thursday, 10/18 (TAG: Wed, 10/17) .
Part 1: Write the definition of each word.
1. mineral: an object that is solid, formed in nature, and never been alive
2. rock: a naturally formed solid made of one or more minerals
3. igneous rock: a rock that was once hardened and then cooled and hardened
4. sedimentary rock: rock formed from material that has settled into layers
5. metamorphic rock: rock that has been changed by heat and pressure
6. rock cycle: an endless process of rocks changing from one kind of rock to another
7. humus: the part of soil made up of broken down pieces of dead plants and animals
8. weathering: the breaking down of rocks into smaller pieces
9. erosion: the movement of weathered rock and soil
10. loam: soil that is a mixture of humus, sand, silt and clay
Label the rock cycle and be able to explain it.
Explain the rock cycle in words: An endless process of rocks changing from one kind to another over time. Any rock can end up underground, and with temperature and pressure, it can cause a rock to change to a metamorphic rock; wind and water break down rocks and cause them to change to form sedimentary rocks, and any type of rock that heats and cools can become an igneous rock.
What is erosion? After rocks are broken down, erosion moves the pieces. Moving water, slow creep, rainfall, and flood can all cause erosion.
Draw a picture of erosion.
(picture must show movement of rock, soil and sand)
What is weathering? Weathering is the breaking down of rocks into smaller pieces. Water is a main cause of weathering as well as wind and ice.
Draw a picture of weathering.
(picture must show a natural element breaking down rock into smaller pieces – like a cliff for example)
