The lithosphere or the land sphere are the plates that are surface layers of the earth. And this lithosphere is made up of Silicon and Aluminium components. The Lithosphere is divided into upper and lower parts by the thick layers of sedimentary rocks.
It constitutes of hard, rigid and outer skins of earth. On lithosphere, the entire biosphere that's the life sphere is based. There are two types of lithosphere i.e oceanic and continental the oceanic has a <u>density of 2.9 grams, and crust on land has 2.7 grams</u>.
Composition Of oceanic lithosphere is of mafic and ultramafic. The asthenosphere is a layer that forms underneath this zone and is in liquid molten forms. This also divided into three zones the upper zone, transition zone, and lower zone.
Melting of rock mass takes place in this layer as it has a depth of 2900 km and the boundary is defined by stress zone that deforms easily and has elasticity. Most of the earthquake waves and lava plums come out of this zone. It's composed of heavier metals like Iron and Aluminium, nickel, etc.
Yes, stencil one overlaps exactly with the original image. The original pattern is now hidden behind stencil one. Each point on stencil one corresponds with a point on the original image.
Like earth, venus does not have any major faults or folds or rift valleys ridges on its surface thus it does not have any global tectonic or plates of rock in rotation.
Being a terrestrial planet, the seismic data collected from the moment of inertia and possible due to the planet plates are too rigid to move but the phases of volcanoes have been found in the craters in addition mountains, and valleys are commonly found on rocky lands points out to some degree of tectonics present under the planet.
Also, the size and structure of the plan tell about its core, mantle and crustal zones. Also, venus is supported to have a magnetic field not as strong as the earth which is induced by the ionosphere and Solar Winds.
