Detailed explanation-1: -The lithosphere is the solid, outer part of Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure.
Detailed explanation-2: -Answer. Explanation:The plates “float” on the soft, plastic mantle which is located below the crust.
Detailed explanation-3: -The topmost layer of the Earth is called crust. It is the thinnest out of all the layers of the Earth.
Detailed explanation-4: -The correct answer is option 2 i.e. Crust and Upper mantle. The lithosphere, that is the rigid outer part of the earth with thickness varying between 10-200 km. It includes the crust and the upper part of the mantle. Hence option 2 is correct.
Detailed explanation-5: -Earth’s Crust. “Crust” describes the outermost shell of a terrestrial planet. Earth’s crust is generally divided into older, thicker continental crust and younger, denser oceanic crust. The dynamic geology of Earth’s crust is informed by plate tectonics.
Detailed explanation-6: -The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly composed of basalt.
