1. At approximately what depth does wet granite reach its melting temperature and generate magma? in kilometers2. Oceanic crust and the underlying rocks to a depth of about 100 kilometers have a basaltic composition. Does the melting curve for basalt indicate that the lithosphere above approximately 100 kilometers has or has not reached the melting temperature for basalt? Therefore, at those depths, should basalt be solid or molten?The melting temperature ______ been reached.Basalt should be_______.3. At approximately what depth does basalt reach its melting temperature? \At a depth of approximately _______ km.4. What is the name of the layer that begins at a depth of about 100 kilometers and extends to approximately 600 kilometers ?
