\nEarth\u2019s oldest-known evolved rocks, which are four billion years old, may be the result of asteroids slamming into the Earth\u2019s crust and causing it to melt. The study found that Earth\u2019s oldest evolved, or granitic, rocks, which form part of the Acasta Gneiss Complex in\u00a0The\u00a0Northwest Territories, have compositions distinct from those typical of Earth\u2019s ancient continental crust. These differences suggest they formed through a different process.
