How hot is lava from a volcano?
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).
Can you freeze lava?
When molten rock or lava freezes it forms crystals. If the rock freezes quickly the crystals do not have time to grow very big. Lava that runs out of volcanoes cools down quickly.
