What Causes rock to flake off in layers?
Different erosional features can lead to layers of rock flaking off. In layered sedimentary rocks this is usually the case when some of the layers are less resistant against weathering (e.g. when the grains are cemented by carbonate which is dissolved by acid rain). One can often see that phenomenon on old sandstone buildings. Also igneous rocks show the effect of layers flaking off the surface. This may be related to thermal expansion and contraction working mostly on the outer part of large boulders. It might as well have something to do with the structure of the rock inherited from its crystallization and residual stresses and the depth that water can penetrate and weather the rock. Another answer: The flaking off in layers of rocks is called exfoliation. This usually occurs in deserts and is caused by changes in temperature.
Which type of rocks are produced by changing other rocks with high temperature and pressure underground?
Metamorphic rocks are produced by changing other rocks with temperature and pressure underground.
High pressure and high temperature cause rocks to?
High temperature and pressure can cause rocks to change their forms. This is known as metamorphic.High pressure and high temperature can cause rocks to change forms. This is known as metamorphic.
What conditions change igneous rocks and sedimentary rocks into metamorphic rocks?
Increased temperature and/or pressure.
What rocks are formed from high temperature and pressures?
Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.

Why Marble is a sedimentary rock?
It isn't, it's what is called metamorphic rock. Metamorphic rocks are composed of minerals that have been exposed to extremes of pressure and intense heat by the Earth's inner temperature, causing them to meld together and recrystallize in a hardened form. Marble is composed mostly of carbonate minerals such as calcite and dolomite.
Which type of rocks are produced by changing other rocks with high temperature and pressure underground?
Metamorphic rocks are produced by changing other rocks with temperature and pressure underground.
Which type of rocks are produced by changing other rocks with high temperature and pressures underground?
Metamorphic rocks are produced by changing other rocks with temperature and pressure underground.
What 2 things must increase for metamorphism to occur?
For metamorphism of rock to occur temperature and pressure must increase. Rocks created in this manner are called metamorphic rocks.
High pressure and high temperature cause rocks to?
High temperature and pressure can cause rocks to change their forms. This is known as metamorphic.High pressure and high temperature can cause rocks to change forms. This is known as metamorphic.
What conditions change igneous rocks and sedimentary rocks into metamorphic rocks?
Increased temperature and/or pressure.
How are igneous rocks changed to metamorphic rocks?
By high pressure and temperature
What rocks are formed from high temperature and pressures?
Igneous, metamorphic, and sedimentary rocks can be changed by high temperatures and pressure, and the resultant rock is called metamorphic, because its form has been changed.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
What are rocks in the sea called?
the rocks are called irone
