Some minerals start out in liquids that are that hot.
There are places inside Earth where rock will melt.
Melted rock inside the Earth is also called molten rock or magma.
Magma is a molten mixture of substances that can be hotter than 1,000 C.
Magma moves up through Earth’s crust, but it does not always reach the surface.
When magma erupts onto Earth’s surface, it is known as lava.
