GEOLOGY

Detailed explanation-1: -Magma is extremely hot liquid and semi-liquid rock located under Earth’s surface. When magma flows onto Earth’s surface, it is called lava.

Detailed explanation-2: -Pahoehoe (Pa-Hoy-Hoy) lava flows are very hot, thin and runny. When it cools is has a smooth to ropey texture because of the low silica content which makes it cool quickly.

Detailed explanation-3: -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.
