As the old crust enters the mantle it brings volatiles such as water with it. This lowers the melting point of the rock around it.This melted material rises to the earths surface under pressure along with gases and may erupt in a volcano.
Sedimentary rocks are rocks made out of sediment, which is often other rocks ground down to powder. Metamorphic rocks are sedimentary rocks that have been changed (partially melted and hardened) by being exposed to extreme heat and pressure. So, yes.
Igneous
No! Bubble wrap is actually melted down q-tips melted down into the form of a guitar and then sculpted into the form of bubble wrap.
Plastic is melted by applying thermal energy -- heat. Plastic "bits" are dumped into a hopper, and a screw type feed mechanism forces them through a heated section of the screw housing. Resistance heating elements are used, and they convert electricity to heat energy to melt the plastic. The temperature is controlled by electronics, and run appropriately for the type of plastic being melted. This melted plastic is then forced out the end into molds in a process called injection molding.
It is called the asthenosphere.
The asthenosphere is located in the upper part of the Earth's mantle, below the lithosphere. It is composed of partially molten rock that is ductile and flows slowly, allowing tectonic plates to move on top of it.
Benioff zone
Partially melted snow is........ partially melted snow!
Pumice is a solid material; it is not melted although it used to be melted rock when it was originally formed by a volcano.
Sleet
The asthenosphere is composed of partially melted, ductile rock that lies beneath the Earth's rigid lithosphere. It is located in the upper mantle and its low viscosity allows for the movement of tectonic plates.
Lava....when its under the earths crust its called magma.
