The Asthenosphere Is Composed Of Basalt And Granite

The oceanic crust is the younger and denser type of crust.

The asthenosphere is composed of basalt and granite.

The asthenosphere ancient greek. The spinning of the asthenosphere made of iron and nickel explains why earth has a magnetic field. It has an average composition consisting of granite with a density of 2 7 g cm 3. The lithosphere is composed of the oceanic and continental crust along with the brittle uppermost mantle.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. It has an average thickness of 7 km much thinner than the continental crust. Oceanic crust diorite basalt rhyolite ultramafics. The asthenosphere is solid but mobile while the lithosphere is solid and relatively rigid.

Asthenosphere granite and rhyolite basalt and gabbro. It is composed of basalt a dark igneous rock with a density of 3 0 g cm 3. The asthenosphere is solid but mobile while the lithosphere is solid and relatively rigid. Convection currents form because of differences of temperatures and density in a fluid.

Which region of earth is composed of abundant amounts of granite. Granite and are composed predominantly of feldspar and quartz. I need this information for a project i am doing.

Sills dikes laccoliths pillow basalts. The continental crust is mainly granitic and the oceanic crust is primarily basalt. Match the tectonic boundary with its direction of motion. Two plates move toward each other.

The upper mantle can be divided into the asthenosphere and lithosphere based on what physical properties. I know that oceanic crust is made of basalt and that continental crust is made of thick granite but i do not know what the asthenosphere mantle is made of. What is the asthenosphere made up of. The earth s outer core is made of basalt and granite.

Continental crust is mainly composed of whereas oceanic crust is mainly composed of.
