1-The processes that change one rock into another rock.

2-the rock formed by the process of cooling magma or lava.

3-The processes that forms sedimentary rocks.

4-The process that forms igneous rock .

5-The reaction of oxygen with iron creating red rust color.

6-The landform where acidic groundwater creates a cave by erosion and then the roof collapses.

7-The changing of existing rock by the process of heat and pressure.

8-the rock produced by the process of compaction and cementation.

9-The molten material formed by melting and found under the earth's crust.

10-The movement of sediment by water,wind,gravity, or ice.

11-The landform where wind deposits sand onto a mound or hill.

12-The process that forms magma.

13-This type of igneous rock is formed by the cooling of lava outside the earth's crust.

14-The landform where a river deposits sediment at the mouth in a fan-shaped pattern.

15-The molten material that is above the earth's crust.

16-this type of igneous rock is formed by the slow cooling of magma inside the earth's crust.

17-The smaller particles of rock produced by the process of weathering.

18-The breaking down of any rock type into sediment.

19-The processes that forms existing rock into metamorphic rock.
