Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks. Which best describes the next step in the formation of metamorphic rocks?

Buried rocks melt deep within the mantle.

Lava melts underlying rocks, which crystallize into new minerals.

Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.

Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.

Consider a one meter long horizontal pipe with a constant 100 cm^2 cross sectional area. water flows rightward into the pipe at x = 0 with flow velocity 02m/sec at every point within the pipe intake area. at x=1, the rightward flow rate is 0.192 m/sec. assume the water is a conserved quantity in the pipe, so there must be a leak (a sink) somewhere in the pipe. 1. compute net volumetric flow of the source if the system to be in equilibrium. 2. now assume the pipe in the problem has no leaks. compute the net volumetric rate of change for the system.
