Answer to Question 1

That sedimentary rock formed due to heating.

Answer to Question 2

Melting occurs because the melting temperature decreases with decreasing pressure. Peridotite in the mantle rises to a lower depth at divergent boundaries with little or no decrease in temperature. The lower depth corresponds to lower pressure. The lower pressure results in a lower melting point and the peridotite partly melts.
