What process causes rocks to crack?
heat and extreme pressure. also water freezing and melting.
What kind of weathering causes repeated expanding due to the heat and contracting due to cold strains the rocks and causes them to crack?
Thermal expansion causes repeated expansion and contraction within the rock. This repeated stress breaks bonds and eventually causes the rock to crack. Thermal expansion is classified as a type of physical or mechanical weathering.
Where does plant root growth weathering happen?
Trees bushes and other plants root in cracks in rocks and continue to grow causing the crack to open more.
What is smoking rocks?
smoking crack
What causes sun or forest fires to crack rock?
not 100% sure but I think it's that the rocks expand when they get hotter and then as the contract when they cool down cracks appear

Why do natural sediments vary in size?
Overtime rocks are broken down by weathering and erosion which causes the sediments to vary in size
What are organisms that have roots that can crack rocks?
Plants are the organisms which have roots and can crack rocks
What are the causes of expansion and contraction of water on soil formation?
in the daytime the suns heat expands rocks.and in the night it contracts. this causes the rocks to crack and eventually breakdown which foorms soil

Changes in pressure which can cause rocks to crack is an example of what?
Changes in pressure which can cause rocks to crack is an example of mechanical weathering. It refers to the disintegration and decomposition of rocks.
What is smoking rocks?
smoking crack
Do you put crack rocks in cigarettes?
no
How ice breaks rocks?
It can do this in two ways. # The Ice can hold rocks in itself and rub these (like sandpaper) across other rocks as it moves, this causes the rocks being rubbed together to break.This is called abrasion. # It can also break rock as it freezes, this is because when water freezes it expands and thus if water enters a crack in a rock then freezes in the crack the ice will try to force the crack open and over time this breaks up the rock. This is called freeze-thaw.
Temperatures in the desert vary greatly between the day and night The constant heating and cooling causes the rocks to crack?
yes, the process is called exfoliation

not 100% sure but I think it's that the rocks expand when they get hotter and then as the contract when they cool down cracks appear
