WebIt has a mass of 4.01 × 10 24 kg and thus makes up 67% of the mass of Earth. [1] It has a thickness of 2,900 kilometers (1,800 mi) [1] making up about 84% of Earth's volume. It is predominantly solid but, on geologic time scales, it behaves as a viscous fluid, sometimes described as having the consistency of caramel. WebThe lithosphere is the solid outermost shell of our planet. The lithosphere includes the crust and the upper part of the mantle, and is made up of material from both the continents and the oceans on the Earth's surface. The lithosphere is vital to humans as this is the part of the Earth that we live on and can easily access.

Web24 apr. 2024 · The composition of a lava rock is a function of its mineral structure and chemical arrangement. One factor determining an igneous rock's composition is its classification as either a felsic or mafic rock. Felsic rocks are dominated by silicon and aluminum minerals, whereas mafic rocks are dominated by magnesium and iron minerals.
