The hot plastic-like rocks in the asthenosphere rise towards the Earth's surface due to convection currents within the mantle. As the hotter, less dense material rises, it creates upward movement of magma, which can eventually lead to volcanic activity at the surface. This process is driven by the heat generated from radioactive decay and the heat left over from the formation of the Earth.
The process that causes hot solid rock to rise through the mantle is known as mantle convection. This occurs when heat from the Earth's core causes the mantle material to become less dense and rise, creating convection currents. As the hot rock ascends, it may partially melt and contribute to volcanic activity at the surface. This process is often associated with tectonic plate boundaries, where the movement of plates can facilitate the rise of hot mantle material.
Subduction results from convection in the asthenosphere. The heat from the core of the earth that is imparted to the mantle causes the mantle to convect much the wayboiling water convects in a pan on the stove. Hot mantle at the core-mantle boundary rises while cool mantle sinks, causing convection cells to form.
A phenomenon that causes certain materials to glow (without getting hot) when electrically excited.
No, living things cannot be found in the asthenosphere. The asthenosphere is a region of the Earth's mantle that consists of hot, solid rock that is capable of flowing over long periods of time. Conditions in the asthenosphere are too extreme to support life.

The hot plastic-like rocks in the asthenosphere rise towards the Earth's surface due to convection currents within the mantle. As the hotter, less dense material rises, it creates upward movement of magma, which can eventually lead to volcanic activity at the surface.

All of the Earth's mantle is hot. And while some geologists believe that there are Mantle plumes (or hot spots) current evidence seems to support a view that mantle plumes do not exist. What causes magma to rise up from the lower crust and mantle is the convection of the mantle and therefore the places where most heat (and magma) is coming up to the surface is along the mid oceanic ridges.
Convection
The process that causes hot air to rise is called convection. As air is heated, it becomes less dense and more buoyant, causing it to rise. This creates vertical air currents that continuously cycle warm air upwards.
Because it gets filled with hydrogen and it causes it to rise since it gets how. As we know hot air rises. Because it gets filled with hydrogen and it causes it to rise since it gets how. As we know hot air rises.
The movement of liquid rock in the asthenosphere is mainly driven by convection currents, a process where hot rock rises, cools, and then sinks back down. This flow is due to the heat generated by the Earth's core, causing the asthenosphere to slowly move and deform over time.

Subducting oceanic crust is more dense and colder than the surrounding hot pliable rock of the asthenosphere.
