How does the subducting plate affect temperature in the asthenosphere?
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 block of ice is left in the sun what is that process called?
The process of a block of ice turning into water when left in the sun is called melting. The heat energy from the sun causes the ice to absorb energy, which raises its temperature and causes the solid ice to turn into a liquid.
What process causes rocks to crack?
heat and extreme pressure. also water freezing and melting.
Which process in the rock cycle causes magma to form?
Magma forms through the process of partial melting of rocks in the Earth's mantle. This can occur due to the intense heat and pressure in the mantle, causing certain minerals within the rocks to melt and form magma.
What causes the asthenosphere to be molten?
The asthenosphere is partially molten due to high temperatures caused by the heat from the Earth's core. The combination of high pressure and temperature in the asthenosphere allows the rock to deform and flow slowly over geological timescales. This partially molten layer allows the lithospheric plates above to move and interact, driving the process of plate tectonics.

What process is responsible for transfer of matter and energy in the asthenosphere?
The process responsible for the transfer of matter and energy in the asthenosphere is convection. This is when heat from the core causes the hotter, less dense material in the asthenosphere to rise, while the cooler, denser material sinks back down. This movement of material creates a circular flow of convection currents that transfer energy and move tectonic plates.
What causes the liquid rock in the asthenosphere to move?
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.
Which process in the rock cycle causes magma to form?
Magma forms through the process of partial melting of rocks in the Earth's mantle. This can occur due to the intense heat and pressure in the mantle, causing certain minerals within the rocks to melt and form magma.
What causes the convection currents in the asthenosphere?
The convection currents running through the asthenosphere are widely believed to be the source of movement of the tectonic plates.

How does the process of convection affect the asthenosphere?
Convection within the asthenosphere drives the movement of tectonic plates above it. As warm material rises and cooler material sinks, it creates horizontal forces that contribute to plate motion. This convection process is a key driver of plate tectonics and shapes the Earth's surface through processes like seafloor spreading and subduction.

The asthenosphere is partially molten due to high temperatures caused by the heat from the Earth's core. The combination of high pressure and temperature in the asthenosphere allows the rock to deform and flow slowly over geological timescales. This partially molten layer allows the lithospheric plates above to move and interact, driving the process of plate tectonics.
What role does asthenosphere play in generating magma at a convergent boundary?
At an oceanic subduction zone, the athenosphere is subducted under continental lithosphere, or under other oceanic lithosphere. Friction between these plates causes heat that creates magmas. At a divergent boundary upwelling mantle (athenosphere) decompresses due to reduced pressures, allowing magma to form. This magma is extruded onto the seafloor as pillow basalts, and beneath the seafloors as massive gabbros and sheeted (gabbro) dikes.
What causes a soild to a liquid?
By melting
