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.
If heat and pressure inside the Earth cause a rock to melt, the resulting material would be magma. When magma cools and solidifies, it can form igneous rock. The composition of the magma depends on the original rock material and the conditions under which it melted.
The mantle cause the mantle to flow.

At depths of 50 to 200 km below Earth's surface rocks will 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.
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.

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.
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.

You don't ... You do melt the material inside the hub
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.
