Why does lava melt in the Earth's heart without causing the Earth's crust to melt?

Have you ever wondered why lava in the Earth's heart melts without causing the Earth's crust to melt? Let's find out through this article!

In the volcanic lava there are some lava around the path of molten lava flows that are attracted to the process during the flow to find the way to erupt at the crater. This type of lava is called "captured lava".

The temperature of molten lava has a certain limit.

The temperature of molten lava has a certain limit, even the highest temperature in the lava above the ground is only 1200 degrees Celsius. The temperature of the source of molten lava below the ground is only a little high. never mind.

The source of molten lava is like an iron filled mold in liquid mold.

If the liquid is poured into the sand mold (quartz-siliceous sand is main), it causes the surrounding sand to melt, but it does not have the stored heat to make the molten mold collapse.

Melting lava flow.

Molten lava also cannot collapse the thick walls of the Earth's crust around the volcanic stream that flow through, at most only affecting the surrounding lava, causing the fusible components to be mixed in. in molten lava flows, like "captured lava".

Even the melting lava reserves are like boiling water flowing very in vitro, just rushing along the path of the volcano.

So molten lava will not melt the Earth's crust.
