1. Lithosphere
ROCKS AND SOIL

2. Rocks Rocks are heterogeneous solids composed of many minerals
Formed by water pressure – sedimentary
Formed through volcanic activity – igneous
Transformed rock - metamorphic

4. Igneous Formed when magma cools and solidifies
Two types: extrusive and intrusive
Extrusive: magma that cools rapidly upon contact with air
Intrusive: magma that solidifies below the surface

6. Sedimentary Accumulation and compaction of debris
Through time air and water break down rock, through erosion, this crumbled rock combine with animal and plant remains and accumulate successive layers, finally compacting into sedimentary rock.
Formed when sediments (sand clay, and silt) are compressed and become solid rock

7. Shale is the most common sedimentary rock
Sedimentary rocks cover about three-quarters of the land surface

8. Metamorphic
A metamorphic rock is any sedimentary or igneous rock that has been changed, or morphed, because of pressure and heat
Metamorphic rocks are made deep inside the earth where heat and pressure change the rocks.
