What are two main classifications of igneous rocks?
The two types of igneous rock are are intrusive and extrusive, depending on where they form. Intrusive igneous rock forms underground from slow cooling magma. Extrusive igneous rock forms at or near the surface from quick cooling lava.
What are two processes a rock must undergo before it can become in an igneous rock?
Two processes a rock must undergo before becoming an igneous rock are melting, where the rock is heated to a point where it turns into magma, and cooling, where the magma solidifies to form an igneous rock.
What two processes labeled in the rock cycle must occur in order to change any rock into an igneous rocks?
The two processes in the rock cycle that must occur in order to change any rock into an igneous rock are melting (to form magma) and solidification (to form igneous rock). Melting of existing rocks due to high temperatures or pressure creates molten magma, which can then cool and solidify to form new igneous rocks.

A lava flow is an example of an igneous rock one of the two main igneous rock groups?
It is an example of extrusive igneous rock.
Which two types of rock can form on the Earth's surface?
Some types of igneous and sedimentary rocks can form on Earth's surface.
What two rock types are formed by transfer of heat?
Igneous an Metamorphic are the two types of rock that are formed with the help of heat .
What are the two major factors that influence the creation of an igneous rock?
Rate of cooling of the magma and Chemical composition of the magma.
What kind of rock does magma form when it hardens?
If the magma cools on the surface of the crust, it is called extrusive igneous rock, such as pumice, basalt or rhyolite. If the magma cools inside the crust, it is called intrusive igneous rock, such as granite.
What are two types igneous rocks?
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.
