Question

What happens to the molten rock when they reach earth surface

Answer 1

Answer:

Magma is extremely hot liquid and semi-liquid rock located under Earth's surface. This magma can push through holes or cracks in the crust, causing a volcanic eruption. When magma flows or erupts onto Earth's surface, it is called lava. Like solid rock, magma is a mixture of minerals.

Answer 2

The molten rock becomes lava at the earth's surface

Explanation:

• The earth's core is a continual boiling mass of red hot molten rock with increasing expanded pressure, which is only held in place by the earth's surface's outer layers of cooling and cooled rock.
• The red hot lava is jettisoned and spews out from the surface with incredible force due to this ever-increasing pressure, and this is how a rising volcano is produced.
• When the red-hot molten lava cools, it solidifies into solid hard rock or granite, which repairs and plugs the fissure leak, allowing the huge pressure to be retained once more.
