How hot is lava?

The temperature of lava flow is usually about 700° to 1 250° Celsius which is 2 000° Fahrenheit. Deep inside the earth usually at about 150 kilometers the temperature is hot enough that some small part of the rocks begins to melt. Once that happens the magma (molten rock) will rise toward the surface (it floats).

What is inside a dead volcano?
