What else can I help you with?
Igneous rocks can look very different depending on?
Igneous rocks look different depending on how fast the magma cools.
How can you get different igneous rocks from the same magma body?
Magma underground may differentiate and form different intrusive igneous rock. Magma from the magma body may erupt, cool, quickly, and form fine-grained extrusive igneous rock, or partially remain underground and form intrusive igneous rock. The type of igneous rock formed from the magma body will largely depend on whether or not it is erupted, and the speed of its cooling.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Why don't igneous rocks look like magma rocks if igneous rock is formed from magma?
Because that is the very definition of igneous rock.
Igneous rocks can look very different depending on?
Igneous rocks look different depending on how fast the magma cools.
How are metamorphic rocks igneous rock and sedimentary rocks different?
Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
One magma can produce several different igneous rocks having different mineral compositions?
Yes, a single magma chamber can produce different types of igneous rocks due to variations in cooling rates, pressure, and mineral content within the chamber. As the magma cools and crystallizes, different minerals may form at different times and temperatures, resulting in the formation of diverse igneous rocks with varying mineral compositions.
How can igneous rocks be different densities?
Igneous rocks vary greatly in composition and method of formation, resulting in diverse densities.
How many types of rocks?
There are lots of different types of rocks in the world.
When molten rocks cools what rocks form?
igneous rocks
How can you get different igneous rocks from the same magma body?

The type of igneous rock formed from the magma body will largely depend on whether or not it is erupted, and the speed of its cooling.
What two conditions are necessary to form igneous rocks?
Increased temperatures and or decreased pressures.
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.
What is one way igneous sedimentary and metamorphic rocks are different?
igneous rocks are made of lava that cools and hardens and metamorphic rocks are madeby heat and pressure.
What rocks are formed from molten rock that has solidified?
Igneous rocks, which come in many different forms.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
