Freeze/thaw cycles expand existing fissures in existing rock by the expansion caused by ice crystal formation. This leads to further erosion of the rock by freeze/thaw and chemical weathering from rainwater.

How does erosion effect the rock cycle?

erosion can effect the rock cycle by turning igneouse and metamorphic rocks into sediments and eventualy turn into a sedimentary rock such as sandstone


What effect do roots have on rocks?

Certain plants are able to get their roots into cracks in rocks. As the plant grows, the thickening roots may force the crack to widen. That, and the expanding ice in winter, may crack the rock wide open.


What happen to minerals when rocks becomes a metamorphic rocks?

Metamorphic rocks are created from rocks that are deformed by tectonic forces and/or are brought to temperature that are much different from those that they were first formed in (usually hotter). The effect of increased temperature is the growth of minerals from others that are no longer stable under the changed pressure and temperature conditions (e.g. diamond is formed from graphite under very high pressure and garnet growths at high temperatures and pressures from aluminium rich usually sedimentary rocks). The effect of shear stress on the rock (i.e. directed force creating not only compression but also deformation) is the change of shape of minerals as well as rotation and alignment of platy minerals into bands. These processes lead to the usually banded appearance of metamorphic rocks.


Which has the greater effect of an earthquake in solid rocks or in compacted sand?

The amplitude of seismic waves is typically much lower in solid rocks than in sediments such as sands. As such the seismic waves in sediments will cause more damage than those travelling through solid rock. For more information, please seethe related questions.


Rocks formed from weathered debris from preexisisting rocks are called?

They are called clastic sedimentary rocks.
