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.
What are signs of weathering?
Signs of weathering include the gradual disintegration or wearing away of rocks and other materials on the Earth's surface due to exposure to environmental factors such as water, wind, and temperature changes. Common signs of weathering include cracks, fractures, flaking, and the rounding of sharp edges or corners on rocks and other structures. Weathering can also lead to the formation of soil and sediment.
When rocks wear away its called?
When rocks wear away, it is called weathering. Weathering is the process by which rocks are broken down into smaller pieces due to exposure to environmental factors like water, wind, temperature changes, and chemical reactions.
What are rocks in the sea called?
Rocks in the sea are typically referred to as sea rocks or underwater rocks. They can also be called submerged rocks or marine rocks.
High temperature and pressure cause igneous rocks to become what type of rock?
High temperature and pressure on igneous rocks cause them to transform into metamorphic rocks through a process called metamorphism. This process typically involves recrystallization of minerals and changes in texture and structure without melting.
What is the flaking of rocks due to temperature extremes?
Flaking of rocks due to extrmees of temperature is called freeze-thaw erosion or exfoliation.

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 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.
What are rocks in the sea called?
Rocks in the sea are typically referred to as sea rocks or underwater rocks. They can also be called submerged rocks or marine rocks.
When rocks are heated above a specific temperature called they loose there magnetism?
When rocks are heated above a specific temperature called the Curie temperature, they lose their magnetism. This is because the heat causes the magnetic minerals within the rock to lose their alignment, disrupting the magnetic field.
High temperature and pressure cause igneous rocks to become what type of rock?
High temperature and pressure on igneous rocks cause them to transform into metamorphic rocks through a process called metamorphism. This process typically involves recrystallization of minerals and changes in texture and structure without melting.
What is the process in which rocks first bend and then break?
The process in which rocks first bend and then break is called deformation. Deformation occurs when rocks experience stress, which can be caused by tectonic forces, pressure, or temperature changes. Initially, rocks may bend or fold under this stress, but if the stress is too great, the rocks can eventually break or fracture.
At night the outside of rocks cool and what else does it do?
Well what it does is it contracts. Contract means to get smaller
