4. When rocks are broken down into smaller pieces by wind, water, ice, plants, or changes in temperature.
6. It’s a type of rock that forms when heat and pressure change an existing rock into a new kind
10. A delta is the triangle-shaped area at the end of a river made of sand, mud, and silt that the river drops off.
11. The process where sediments are pressed together under pressure, so the spaces between the particles get smaller and they stick together.
13. The process where weathered rock and soil are moved from one place to another by wind, water, ice, or gravity.
14. It’s the process where a liquid cools or evaporates, and solid crystals form from it.

1. It’s a type of rock that forms when magma or lava cools and hardens
2. Small pieces of rock, soil, or other materials that have been broken down by weathering and moved by erosion.
3. It’s the rigid, outer layer of the Earth made of the crust and the top part of the mantle.
5. When sand, mud, or tiny rocks get squished and glued together to make a real rock.
7. It’s a type of rock that forms when layers of sand, mud, or tiny pieces of rock are pressed and cemented together over time
8. It’s the process where sediment, soil, or rocks are dropped and added to a new location
9. A naturally occurring, nonliving solid that has a crystal shape and a specific chemical makeup.
12. cycle It’s the never-ending process that shows how one type of rock can turn into another over time.
16. A naturally occurring solid made up of one or more minerals.
