Basalt And Granite In Earths Layer

Basalt and granite in earths layer.

Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed. As two rocks are not same it s fun to compare them. Ranges from 1 70 km thick. Layer of rock that forms earth s outer surface.

Both are igneous rocks which means that they cooled from a magma the earth gets very hot just below the surface and there is lots of liquid rock available. Basalt vs granite information. Granite is formed from magma that cooled slowly so it has a coarse grained texture. The crust is composed of two basic rock types granite and basalt.

Notice how thin the crust of the earth is in comparison to the other layers. In relative terms it s thickness is like that of the skin of an apple. Earth s outer layer is covered by rocks and these rocks have different physical and chemical properties. Made up of granite and basalt hottest spot is about 1 500 celsius continental crust crust that forms the continents.

The sub layers of crrust is continental and oceanic crust witch are both solid and oceanic composition is basalt and the other granite. Made of mostly granite rock. The continental crust is composed mostly of granite. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

You can also know more about basalt and granite reserves. Geologists love river canyons the scars made by landslides and even a few. All rocks of igneous origin consist of magma or molten earth that finds its way up to. It amounts to less than half of 1 percent of the planet s total mass but plays a vital role in most of earth s natural cycles.

That s the only reason granite point is exposed. The seven continents and ocean plates basically float across the mantle which is composed of much hotter and denser material. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. It may be pink white gray or light to moderate yellow.
