Which family of rock is formed from weathering?
Clastic sedimentary rock is the usual type of rock formed from the products of rock weathering.
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
What effect does weathering have on igneous rock?
The effect of weathering is to reduce the volume of the igneous rock.
Is Gabbro iron rich?
Yes. Gabbro, an igneous rock, has iron-bearing hornblende and augite.
The process that breaks down rock and other materials at earth's surface is called?
It is called weathering. Erosion is the weathering and movement of rocks and rock fragments.
Which family of rock is formed from weathering?

What type of rock is likely to form next when extrusive igneous rock is broken down by weathering?
Sedimentary
What type is rock is likely to form next when extrusive igneous rock is broken down by weathering?
Sedimentary
Once the rock is formed will it always be an igneous rock?
It is possible, but not likely. It is more likely to undergo metamorphism, or be subjected to weathering and erosion, and end up as a different type of rock.
The formation of natural rock bridges in dry regions is most likely a result of?
weathering
Chemical weathering occurs when minerals in rocks are changed chemically. Which of these will most likely change the rate of chemical weathering on a rock?
rainfall and temperature
Essential minerals of rock basalt?
anorthite-rich plagioclase, feldspar and augite
Which area on the earth is likely to have the highest rates of weathering both mechanical and chemical?
Tropical areas experience the highest rate of mechanical and chemical weathering of rock.
What type of chemical weathering is most likely to affect a rock containing calcite?
Dissolution from acidic rainfall.
What is weathering that does not alter the chemical composition of the rock called?
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
While physical weathering will break a rock into chunks what turns the rock into soil?
chemical weathering
When does a rock have lower rate of weathering?
a rock would have a lower rate of weathering when it has more surface area exposed to weathering.
