The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid.The rocks are less dense than the rocks in the lithosphere.
Introduction. The lithosphere is the solid and rigid outer layer of our planet. It includes the crust and part of the upper mantle that contains rigid rocks. Beneath this layer is the asthenosphere where the rocks in this part of the upper mantle are not rigid. The rocks can flow like a liquid or break apart similar to silly putty. Two types of crustal plates. The Earth's Crust, Lithosphere and Asthenosphere. Crust, the upper layer of the Earth, is not always the same. Crust under the oceans is only about 5 km thick while continental crust can be up to 65 km thick. Also, ocean crust is made of denser minerals than continental crust. The tectonic plates are made up of Earth s crust and the upper part of the mantle layer underneath. Together the crust and upper mantle are called the lithosphere and they extend about 80 km deep. The lithosphere is broken into giant plates that fit around the globe like puzzle pieces The asthenosphere is a weaker layer that flows right underneath the lithosphere. Together, the lithosphere and the asthenosphere comprise what scientists refer to as the earth’s mantle. There are two different kinds of lithosphere which together make up the earth’s surface, or crust. The oceanic lithosphere is essentially what is referred to as the ocean floor.  The asthenosphere (from Greek ἀσθενής asthenḗs 'weak' + sphere) is the highly viscous, mechanically weak and ductilely deforming region of the upper mantle of the Earth. It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface. The Lithosphere-Asthenosphere boundary is usually referred to as LAB. The asthenosphere is generally solid, although some of its regions could be melted (e.g. below mid-ocean ridge). The asthenosphere is composed of the layer of mantle below the lithosphere where the rock has plastic like qualities and is able to bend and deform without breaking. The Ear … th's crust is the uppermost layer of the Earth and is solid. Rockhound. The lithosphere is composed of the oceanic and continental crust, along with the rigid upper mantle. The asthenosphere is the plastic like upper mantle directly below the lithosphere where rock can move, bend, and deform without breaking. Characteristics [edit]. The asthenosphere is a part of the upper mantle just below the lithosphere that is involved in plate tectonic movement and isostatic adjustments. It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface. The Lithosphere-Asthenosphere boundary is usually referred to as LAB. The asthenosphere is generally solid, although some of its regions could be melted (e.g. below mid-ocean ridge). Asthenosphere. Introduction. The asthenosphere is the layer of the Earth that lies below the lithosphere. It is a layer of solid rock that has so much pressure and heat the rocks can flow like a liquid. The rocks are less dense than the rocks in the lithosphere. The rocks in the upper mantle can be part of the lithosphere or the asthenosphere. Lithosphere rocks are solid and rigid. Rocks below the lithosphere flow and break apart. They also rise through the lithosphere in areas where tectonic plates are separating. Split and merge into it. Answer by Jordan Hauger. Confidence votes 11. The asthenosphere is composed of the layer of mantle below the lithosphere where the rock has plastic like qualities and is able to bend and deform without breaking. The Earth's crust is the uppermost layer of the Earth and is solid.
