What are the 3 types of lava?

There are three basic types of magma: basaltic, andesitic, and rhyolitic, each of which has a different mineral composition.

Regarding this, what are the 4 types of lava?

Because of the role of silica in determining viscosity and because many other properties of a lava (such as its temperature) are observed to correlate with silica content, silicate lavas are divided into four chemical types based on silica content: felsic, intermediate, mafic, and ultramafic. What exactly is lava?

Why is lava so hot?

Lava is hot for two primary reasons: Pressure and radiogenic heating make it very hot deep in the Earth (about 100 km down) where rocks melt to make magma. The rock around the magma is a good insulator so the magma doesn't lose much heat on the way to the surface. Subsequently, is magma and lava the same thing? Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface.

Thereof, which is hotter fire or magma?

What happens when magma rises? The magma rises and collects in chambers within the crust. As magma fills the chamber, pressure grows. If the pressure gets high enough, the magma can break through the crust and spew out in a volcanic eruption. Most explosive volcanoes occur above subduction zones.

People also ask can an extinct volcano come back to life?

Even dormant volcanoes are becoming active and not only that, but also extinct volcanoes are coming back to life. An extinct volcano by definition is dead volcano, which has not erupted in the last 10,000 years and is not expected to ever erupt again.
