The correct answer is:
True
Explanation:
The concept of decompression melting is being applied in the given statement that the release of pressure converts mantle rock from solid to liquid as the decompression melting is the process that involves the movement of the mantle of Earth in an upward direction to an area of lower pressure. The decrease in this overlying pressure facilitates the rock to get melted and then leads to the formation of Magma. Magma is made by the melting of the mantle of Earth. we can also understand this concept by understanding that when the dense material gets to expands by the addition of heat, then it expands more by moving to a place where the pressure of the surrounding environment is much less than where it started, it can continue to expand to the point where it simply begins to melt converting it from solid to liquid.
