Heat. Molten rock can be formed from the subduction and melting of cold, dense, wet oceanic crust at some convergent plate margins. The moisture in the rock assists in the melting of the crust and the rock surrounding it. Magma is also formed at hot spots in the mantle where hot material undergoes decompression melting as it rises. Decompression melting also occurs at the mid-ocean ridges where new oceanic crust is formed from rising mantle rock.
What else can I help you with?
What might cause solid rock in the Earth's interior to melt and begin to flow?
The mantle cause the mantle to flow.
What causes the earth to retain heat and could cause the ice caps to melt?
greenhouse
What depth below earths surface do you have to go before the pressure and temperature cause rocks to melt?
At depths of 50 to 200 km below Earth's surface rocks will melt.
How close would the sun be to earth for it to melt?
it's is impossible for earth to melt but if we were 20,000,000 miles closer the earth would not melt but the oceans would evaporate.
Why would a person be unable to dig a tunnel all the way through the middle of earth?
No One Can't Dig A Tunnel In The Middle Of The Earth Because The Tempature Inside Earth Gets Hotter As You Go Deeper. It Is Around 9000F (5000C) In The Center. It Is So Hot Inside Earth That Rocks Melt.
Is it possible to melt something from the inside out?
Gobstoppers Stick 'em in a microwave and they melt from the inside out. Although the outside tends not to melt and they become quite explosive, so don't actually do it.
What is inside the core of the earth?
Earth core consists primarily of molten rock, called Magma. It works as a kind of replacement for the solid crust, slowly absorbing and replacing it. When two continental plates collide, one is forced downwards towards the core to melt, the other is replacing the gap, this is the cause of earthquakes.

What are the forces produced from the inside of the earth and cause sudden changes on its surface?
earthquake
How do you melt cast iron pipe to sewer?
You don't ... You do melt the material inside the hub
Will you die if the earth melts and evaporates?
The earth will never melt. Its ice caps might melt and cause flooding. With high enough heat from the Sun, the floods could evaporate. But the earth changes very slowly, usually, so any catastrophic changes are unlikely to kill anyone alive today.
Is nuclear power plants are bad for earth?
Not normally. If they melt down, they can cause extreme damage. But generally it is a source of good, clean energy.
