Light colored igneous rocks are less what than dark igneous rocks?
basaltic rocks are darker because they are more dence granitic rocks are less dence so they are lighter
In general how does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Light-coloured igneous rocks, such as granite, have a higher silica content and lower iron and magnesium than darker ones, such as basalt. Since iron and magnesium are very dense minerals, this makes darker igneous rocks more dense than lighter ones.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Are igneous rocks made up of igneous rocks?
Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.
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.

What causes igneous rocks to become magma?
Cooling to a solid.
When silica is in a rock does it make it lighter or darker?
Generally, igneous rocks with more silica are lighter in color.
When molten rocks cools what rocks form?
igneous rocks
What causes sedimentary or igneous rocks to turn into metamorphic rock?
Heat and Pressure.
What causes sedimentary and igneous rocks to change?
by melting and cooling
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
Which types of rocks are not metamorphic rocks?
Sedimentary and Igneous rocks are not metamorphic rocks. Metamorphic rocks however are igneous or sedimentary rocks that have undertaken metamorphism (In extreme heat and/or pressure the minerals are forced to recrystalize) and become metamorphic rocks. If the heat/pressure causes the rock to melt into liquid rock than it is no longer metamorphi, it is igneous. Hope this helps :)

Where are the two types of igneous rocks made?
Extrusive igneous rocks , Intrusive igneous rocks
