Magma
Molten rock that has been erupted onto Earth's surface is known as lava. Molten rock within the Earth is known as magma.

The interior of the earth is molten.
As elements decay within the Earth's interior, they release energy. This energy creates movement within the magma (along with the rotation of the Earth and heat) and this movement causes the plates of the Earth to move, hence the geography of the planet is different to thousands and millions of years ago.
TRUE (this is the correct answer)
Tectonic Plate Movement
by pressure of gases within the molten rock
Crystals usually form from molten rock as the molten rock gradually cools.
Magma
Pressure developed within a volume of molten metal.
Molten rock that has been erupted onto Earth's surface is known as lava. Molten rock within the Earth is known as magma.
Calcium can conduct electricity in both its solid and molten state because it has mobile charge carriers. In its solid state, calcium atoms are arranged in a lattice structure and the movement of electrons within the lattice allows for electrical conductivity. In its molten state, the calcium ions are free to move throughout the liquid, facilitating the flow of electric current.
Magma is the molten rock below the crust, in the mantle. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust.
