What else can I help you with?
What do plants do to cause weathering?
As plants grow out from cracks in rock, they push the rock further apart, and eventually it breaks apart.
How can water erode materials?
Water seeps into cracks and breaks apart the rock or water rubs the side of the rock that is exposed and breaks off pieces of the rock.
Name the process when water freezes in a rock and breaks the rock apart?
The process is called mechanical weathering or freeze-thaw weathering. Water seeps into cracks in the rock, freezes, expands, and ultimately breaks the rock apart as the ice expands.
What happens when a shear force acts on rock layers?
It breaks apart
Water in the cracks of a freezes and breaks apart the rock mechanical or chemical?

What happens to the surface area of rock as it breaks apart?
Fracturing increases the surface area of a rock exposed to weathering.
What type of energy is stored in a rock?
Potential energy is stored in a rock due to its position or composition. This energy can be released when the rock falls or breaks apart.
What is the process whereby streams break apart and erode rock is called?
Abrasion. Impacts of sediment grains carried by the water breaks apart and erodes rocks. Your mumma
What is an example of a physical weathering and what is weathered?
An example of physical weathering is freeze-thaw weathering, where water seeps into cracks in rocks, freezes, expands, and causes the rock to break apart. The rock is weathered in this process, as the repeated freezing and thawing weakens and eventually breaks it apart.
How doe ice wedging weathers rock?
Ice wedging breaks the rock apart. Water goes into cracks in the rock and when it freezes, it expands. This can cause rocks to split and eventually break. (see the related link)
What rock has colourless chunk that breaks apart into cubes and has no lustre and is soft enough to be scratched by fluorite?
Calcite perhaps (although it does not form cubes).
How does ice wedging break apart rock?
Ice wedging breaks apart rock by water seeping into cracks in the rock. When the water freezes, it expands and puts pressure on the surrounding rock, causing it to crack and break apart over time. This process is repeated with each freezing and thawing cycle, eventually leading to the disintegration of the rock.
