What is the difference between phreatomagmatic eruption to phreatic eruption? ?

Phreatomagmatic eruptions are volcanic eruptions resulting from interaction between magma and water while phreatic eruption is a steam eruption without lava ejection.The eruptions are caused by groundwater flashing to steam as it is heated by magma.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
