Lava is incredibly important – beneath the earth's crust it keeps the continental plates moving. Its emergence above the crust in lava flows and volcanoes gives us spectacular scenery!

Lava is molten rock generated by geothermal energy and expelled through fractures in planetary crust or in an eruption , usually at temperature from 700 to 1200 celcius . The structure resulting from subsequent solidification and cooling are also sometimes described as lava
Lava is molten rock. It is created deep beneath Earth's surface (often 100 miles or more underground), where temperatures get hot enough to melt rock. Scientists call this molten rock magma when it's underground. Eventually, some magma makes its way to Earth's surface and escapes via a volcanic eruption.

Lavas, particularly basaltic ones, come in two primary types: pahoehoe (pronounced 'paw-hoey-hoey") and aa (pronounced "ah-ah"). Both names, like a number of volcanological terms, are of Hawaiian origin. A third type, pillow lava, forms during submarine eruptions.
