Question

what is the importance of lava?​

Answer 1

Answer:

Although lava can be up to 100,000 times more viscous than water, lava can flow great distances before cooling and solidifying because lava exposed to air quickly develops a solid crust. This insulates the remaining liquid lava, helping keep it hot and inviscid.

Answer 2

Answer:

Lava, magma (molten rock) emerging as a liquid onto Earth's surface. The term lava is also used for the solidified rock formed by the cooling of a molten lava flow.
