Obsidian is quickly cooled lava. When cooled slowly it forms crystals and quartz. Thus obsidian is an amorphous solid like other glasses and it melts over a range of temperatures at roughly the quartz melting point. 1650 C (+/- 75) http://en.wikipedia.org/wiki/Obsidian

In which region of the Earth's interior does the heat increase to the point that rocks can begin to melt?

The heat increases to the point that rocks can begin to melt in the lower part of the Earth's mantle, known as the asthenosphere. This is where the temperature and pressure conditions allow for rocks to melt and form magma.

What region of the earths interior does the heat increase to the point that rocks can begin to melt?

The heat increases to the point that rocks can begin to melt in the region known as the mantle. This layer lies beneath the Earth's crust and is composed of solid rock, but under high temperatures and pressure, some rocks can melt and form magma.

Why don't rocks in earth's lower crust upper crust and mantle melt?

The rocks don't melt because they are under tremendous pressure. High pressure raises the temperature needed to melt something.
