If you are talking about an earthquake, the focus right above it is the epicenter
Rocks
yes
smoking crack
If there is water in the gap, it will freeze. As water expands when it freezes, the crack will be opened wider. This process is called freeze-thaw. Hope that helped!
This is called a fault.== ==
Pressure
Rocks
false
A break or crack along which rocks move is called a fault. Sudden motion along the faults result to earthquakes.
Cracks in rocks of the crust are known broadly as discontinuities. If there is relative movement of the rocks on the two sides of the crack, then it is known as a fault. If there is not then it is known as a joint.
Exfoliation
Exfoliation
yes
Plants are the organisms which have roots and can crack rocks
I believe its called a fault line.
Changes in pressure which can cause rocks to crack is an example of mechanical weathering. It refers to the disintegration and decomposition of 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.
