Answer

Brief Explanations:

Water in volcanic - related processes acts as a flux. It lowers the melting point of rocks by disrupting the crystal - lattice structure of minerals in the rock. Also, it reduces the viscosity of magma, making it more fluid and easier to flow. This is a well - known concept in geology related to magma generation and movement.

Answer:

It lowers the viscosity and melting point of rock.
