<span>In the mantle, heat is transferred as soft rock flows slowly in cycles known as convection currents. convection currents are the currents that are caused due to the process of convection. It is actually one of the three main process of heat transfer. The other two process of heat transfer are conduction and radiation. </span>
The greatest weakness is disintegration caused by early rains previously new development can help stay the dirt in more bone-dry atmospheres sandier soils. The better points of interest are advanced soil supplements as a side-effect of the consumer and evacuating high centralization of harming plants in the Ecosystem.
1. a. Lithosphere
If we divide the Earth into layers by their composition, then there are three of them, the crust, mantle, and core. The crust is the thinnest layer, being on the top, and being solid. The mantle is the second layer, lying between the crust and the core. It is a layer where the temperature and pressure are higher, and the rocks are hot and slow-moving. The core is the bottom layer, in the center of the planet. It is the hottest and has the highest pressure, being the densest of the layers and is composed mostly of iron and in lesser percentage of nickel.
2. b. Crust
The Earth is divided into several layers depending on the layers being solid or liquid. There are five different physical layers, lithosphere, asthenosphere, mesosphere, outer core and inner core. The lithosphere and the inner core are the two layers that are solid, thus the layer on top and the layer in the center. The asthenosphere, mesosphere, and outer core are all liquid, though it is a different degree of liquidity, and it is these three layers where the convection currents occur and cause the magnetic field of the Earth, as well as the tectonic movements.
