What happens to the surface area of rock as it breaks apart?
Fracturing increases the surface area of a rock exposed to weathering.
Upper surface of the area where all the pores in a rock are filled with water?
The water table.
What is the upper surface of area where all the pores in a rock are filled with water?
it is called the water table
What surface processes produces surface formations?
rock
Are you more likely to see sedimentary rocks on the surface or deep in earth's crust?
Of all the rock on Earth's surface, 75% is sedimentary rock. But, sedimentary rock is only about 5% of the whole crust. Unlike igneous rock, which forms underground, sedimentary rock forms from materials at Earth's surface. Which this means that sedimentary rocks are more likely to be seen on the surface. Hope this helps :)
What happens to the surface area of rock as it breaks apart?
Fracturing increases the surface area of a rock exposed to weathering.
What happens to the rate at which a rock will weather when it is broken up and why?
The rate of decomposition of the rock will increase when it is broken up because there is more surface area exposed to the elements weather) that can erode the surfaces.
Does the rate at which a rock undergoes chemical weathering increase or stay the same when the rock becomes more mechanically weathered why?
The rate will increase due to the increase in surface area available for attack by chemical weathering.
How does the surface area of a rock affect the rate of weathering.?
The surface area of a rock has a big affect on the rate of weathering. The higher the surface area of the rock in proportion to its overall mass will result in a quicker rate of weathering of the rock.
Does a smaller rock a have higher or lower percentage of surface area than a larger rock?
It depends on percentage related to WHAT! You cannot express surface area as a percentage of volume since the dimensions are different. So the only percentage you can have is the suface area of the smaller rock as a percentage of the surface area of the larger rock. In that case, the answer, not surprisingly, is that the smaller rock has the smaller percentage surface area.It depends on percentage related to WHAT!

What happens to surface area when rocks are broken into smaller pieces?
As a substance is broken, the surface area greatly increases. For example a 2 meter cube has a total surface area of 24 square meters. If a 1 meter cube is cut out of one corner, the total surface area is now 30 square meters.
If an area is covered in igneous rock what can you tell about that areas past?
The area would have had; a) a plutonic intrusion underneath the surface rock, and the surface rock had eroded away, or b) previous volcanic eruption(s).
What happens when magma rises to the surface?
It cools and solidifies into a sedimentary rock.
What is the area rock immediately above a fault surface?
hanging wall
What happens to a rock when they are uplifted to the surface of the earth?
Pressure on them is released, which can cause pressure-release mechanical weathering. Exposure of an uplifted rock to the surface will fully expose the rock to the effects of mechanical and chemical weathering--basically a rock rot.
What happens when rock and water under the crust become very hot?
Pressures can dramatically increase, causing the rock to melt.
What happens if the percentage of felsic minerals in a rock increase?
it becomes darker and density will decrease (a)
