Are intrusive rocks formed at Earth's surface?
No. Intrusive rocks form when liquid magma "squirts" into the crust and hardens. Igneous rocks that form at the earth's surface are called extrusive rocks.
Explain how igneous rocks form?
Igneous rocks are one of the 3 main type of rocks, the others being sedimentary and metamorphic rocks. Igneous rocks are formed from the cooling of lava and magma. There are over 700 kinds of igneous rocks, and most are found beneath the surface of the Earth's crust.
How are moon rocks similar and different to rocks on earth?
Minerals that make up moon rocks are the same minerals that are found on Earth. Some moon rocks have minerals that combine to form kinds of rocks that are not found on Earth. BlueStar(:
What is vocanicity?
volcanicity is the process where by magma in the interior of the earth crust forced it way out to the earth surface cause by intense pressure in the interior of the crust there by forcing the earth crust to expand and causing a crack which will intend force it self through flowing out to form hard igneous rocks
How does magnetite form?
by earth's crust
What rocks originate from the surface of the earth?
Sedimentary rocks form on the Earth's crust, and can form metamorphic rocks when buried. Igneous rocks form under the surface, or when liquid magma reaches the surface as lava.
Are intrusive rocks formed at Earth's surface?
No. Intrusive rocks form when liquid magma "squirts" into the crust and hardens. Igneous rocks that form at the earth's surface are called extrusive rocks.
What are Igneous rocks that cool quickly beneath Earth's crust called?
Igneous rocks that cool quickly beneath earth's crust are known as intrusive rocks. These rocks will form from magma which will cool and solidify quickly.
Contrast the ways in which extrusive and intrusive rocks are formed?
Intrusive rocks form within the crust of the Earth while extrusive rocks form on the surface.
What are rocks that form Earth's crust?
The rocks of the crust are igneous, sedimentary, and metamorphic in origin. The base rock of the oceanic crust are mainly basaltic and the base rock of the continental crust is mainly granitic.
How did rocks get on earth?
they were and aree forced through earths crust in the form of lava.
What element is abundant in the earth's crust and combines with oxygen to form rocks and minerals?
Silicon
What earth foces cause metamorphic rocks to form?
Pressure through layers of crust

How are moon rocks similar to and different rocks on earth?
Minerals that make up moon rocks are the same minerals that are found on Earth. Some moon rocks have minerals that combine to form kinds of rocks that are not found on Earth. BlueStar(:
What type of mountains are the adirondack mountains?
These are upwarped mountains. They form when blocks of Earth's crust are pushed up by forces within Earth. Over time, the soil and sedimentary rocks at the top of Earth's crust erode, exposing the hard, crystalline rock underneath. As these rocks erode, they form the peaks and ridges.
How are moon rocks similar and different to rocks on earth?
Minerals that make up moon rocks are the same minerals that are found on Earth. Some moon rocks have minerals that combine to form kinds of rocks that are not found on Earth. BlueStar(:
