|
Definition
| Biological Activity, Exfoliation, Unloading |
|

Term
|
Definition
| Unloading occurs when the pressure on the exposed rock is reduced. |

|
Definition
| Exfoliation is when unloading causes the outer layers of rock is contracted until the separate. |

Term
| How does mechanical weathering affect the rate of chemical weathering? |
|
Definition
| If mechanical weathering breaks up the rock, chemical weathering can happen better. |

|
Definition
| Weathering that occurs at different rates. |
