How do extreme temperatures affect rocks?

Answer 1

a long time ago when people disvoverd volcanoes a few years later scientist where studing the volcanoes and the rocks in them so they might of gotton close to one before it fomed into a real volcano. Sothe rocks around the volcano might of stacked echother so it would form into that volcano so the rocks might of been hot so it got hotter and hotter but if it was cold it would freeze and it wouldent have the melted rocks in them to make lava.

Answer 2

If u heat a glass rod and put it into cold water it will crack.this is bcuz the glass on the outside of the rod contracts (gets smaller) wjile the inside remains the same. Similarly, rocks will crack if their temperature changes quickly. This may occur at night after a hot day or when rain falls on hot rocks. Eventually the outer layers of the rock crack and may peel off. This process is very common in granite and eventually rounded boulders are formed.

hope this helped :D

Answer 3

Rocks expand due to heat and contract due to cold. Thus, due to unequal expansion and contraction ,the rocks tend to break and get weathered. Rocks expand due to heat and contract due to cold. Thus, due to unequal expansion and contraction ,the rocks tend to break and get weathered.

Answer 4

Extremely hot temperatures may cause a rock body to metamorphose into another type of rock. The metamorphosis can occur by recrystallization of the existing minerals, or by a chemical exchange between rock types via extremely hot fluids.

Extremes in temperature also affect a rock's formation from molten material. Slow cooling allows for the creation of large mineral crystals in the rock, while quick cooling causes small crystals to form. In the case of volcanic glasses, the rapid exposure upon eruption of ridiculously hot lava to cold water results in very little or no crystal formation.

Extremes in daytime temperatures can cause a type of weathering known as exfoliation, a sloughing off of a rock body's outer skin due to expansion and contraction caused by the temperature differences between the exterior and interior of the rock mass.

Answer 5

Temperature can effect rocks on how hot or cold it is. If the weather is really cold then it might couase the rock to freeze thaw. But if the weather is a nice hot day it will cause the rock to contract and go back to normal

Answer 6

if rocks have cracks in them them water willl get into them and when the water freezes, then the rock will split out.

Answer 7

It transforms/changes their state of matter or existence mostly from solid to liquid or molten form.
