Here's a breakdown:
* Fracture: A break in a rock that does not involve movement of the rock on either side of the break.
* Fault: A break in a rock where there has been movement along the break.
Fractures can be caused by many things, including:
* Stress: Rocks under stress, such as from tectonic plates moving, can crack.
* Cooling: As rocks cool, they can contract and fracture.
* Erosion: Weathering and erosion can also cause rocks to break.
Fractures are important because they can:
* Control the flow of groundwater: Fractures can create pathways for water to flow through rocks.
* Influence the formation of mineral deposits: Fractures can provide channels for minerals to deposit.
* Affect the strength of rocks: Fractures can make rocks weaker and more prone to failure.
