The mantle is the source of molten rock. This molten material can, if the tectonics are right, penetrate up through the solid outer mantle and the crust to deliver lava, which is molten rock (magma) that has reached the surface of the earth.
the crust is made up of solid rock and mantle is made up of molten rocks
Molten rock IS magma. Unless you are talking about lava, which is magma without its gaseous content. But lava is not molten for long.
molten rock bubbles up through the ridge to form new land
The hot molten liquid that rises up through a volcano is called magma. It is a mixture of molten rock, gases, and other substances that is stored beneath the Earth's surface. When a volcano erupts, the magma is expelled as lava onto the Earth's surface.
molten rock or magma
No, molten rock is less dense than solid rock and rises through the crust.

Molten Rock from with in earth can force its way up through the layers above it cooling and forming igneous rock.

The igneous rock is formed when a rock that is solidified from molten or partly molten matierial.

Molten lava.
Density is the key. Think of a hot air balloon. Because hot air is less dense than cool air it rises above it, causeing the air balloon to rise. In science, materials that are a hotter temperature are less dense than materials that are cooler in temperature. The molten rock being hotter is less dense and rises about the cool, solid rock.
Magma is made molten rock. Rock is made up of elements.
