Igneous rocks are formed when magma does what?
The Igneous rock formed when magma cools are; 1. Extrusive (Volcanic) Igneous Rock; which are igneous rocks formed when magma cools outside the earths crust. The texture of of extrusive igneous rock is fine grained. 2. Intrusive (Plutonic) Igneous Rock; these are igneous rocks formed by gradual cooling of magma within the earths crust. The texture is coarse grained.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
How does determining the ages of igneous rocks help to date fossils?
Igneous intrusions that crosscut sedimentary rock that contain fossils can provide a date range because igneous rock is datable by radioactive decay techniques.
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.
When molten rocks cools what rocks form?
igneous rocks

Where are the two types of igneous rocks made?
Extrusive igneous rocks , Intrusive igneous rocks
Could radioactive dating only be used for igneous rocks?
Radioactive dating is only useful in dating igneous and metamorphic rock. Organic material that has not fossilized and does not exceed 70,000 years of age can be dated by Carbon dating techniques. Sedimentary rock can only be dated by its association with igneous and metamorphic rock.
Why are igneous are called primary rocks?
Igneous rocks
Are volcanic rocks igneous rocks?
Yes. Volcanic rocks are extrusive igneous rocks.
Are sedimentary rocks are harder than igneous rocks?
No, igneous rocks are harder than sedimentary rocks on average.
