Weathering is breaking up of rock where it stands. |
|
What is weathering? |
|
|
|
Rocks are broken down into increasing smaller particles: Gravel; Sand; Silt; Clay |
|
Over time, what happens to rocks as they are weathered? |
|
|
|
Weathering can be chemical weathering, in which rocks are broken down when the particles that make them up are changed. |
|
What is chemical weathering? |
|
|
|
Weathering can be physical weathering, in which rocks are broken down when the particles that make them up are not changed. But the forces between the particles are overcome to separate them into small pieces of rock. |
|
What is physical weathering? |
|
|
|
Sedimentary rocks are formed when sediment (little pieces of weathered rock) is laid down in layers under water and then compressed by layers above.
The water between the sediment is squeezed out and the sediment bonds together. |
|
How are sedimentary rocks formed? |
|
|
|
If organisms fall into the sediment then the rock can take the shape of the organism. These formations are fossils. |
|
What may occur when organisms fall into the sediment of a forming rock? |
|
|
|
Metamorphic rocks are formed when either igneous or sedimentary rocks are heated under great pressure. |
|
What causes the formation of a metamorphic rock? |
