Notes on Lithosphere - Unacademy
Webthe lithosphere consists of both types of crust and the uppermost mantle a region generally is higher than an adjacent region if ______ than the adjacent region the crust is thicker geology is the scientific study of earth what is the continental shelf? a fringe of shallow seafloor surrounding the land the two main types of crust on Earth WebThe lithosphere is: composed of the entire crust and the uppermost mantle. The asthenosphere is a layer of low rigidity that separates the rigid lithosphere from the rigid mantle. Most of Earth's volcanic and earthquake activity occurs at … fur from animals

WebIn general, the Earth can be divided into layers based on chemical composition and physical characteristics. Figure 2.2. 1: The layers of the Earth. Physical layers include the … WebA) The asthenosphere is composed of solid rocks associated with the rigid mantle. B) The asthenosphere is a highly viscous layer located beneath the lithosphere. C) The asthenosphere is composed of liquid molten rock. D) The asthenosphere consists partially of crust and partially of mantle. WebEarth's lithosphere, which constitutes the hard and rigid outer vertical layer of the Earth, includes the crust and the uppermost mantle. The lithosphere is underlain by the asthenosphere which is the weaker, hotter, and deeper part of the upper mantle. The lithosphere–asthenosphere boundary is defined by a difference in response to stress. github pumpkin tools
