Question
In what location does rock melt, allowing for igneous rock formation?A.in Earth's inner coreB.In Earth's outer coreC.Between 50 and 200 km below Earth's surfaceD.Between 1000 km and 2000 km below Earth's surface
Solution
The location where rock melts, allowing for igneous rock formation, is C. Between 50 and 200 km below Earth's surface. This region is known as the asthenosphere, a part of the upper mantle, where the temperature and pressure conditions allow for the rock to become semi-fluid and melt. This molten rock, or magma, can then rise to the surface and cool, forming igneous rocks.
