According to scientists, meteorites land everywhere with almost equal probability. However, if they fell in a humid jungle climate, moisture and oxygen would corrode them. In Antarctica, where the climate is extremely dry, the likelihood of corrosion is almost non-existent. In addition to this, naturally, the rocks are easier to spot on the white, icy surface of Antarctica. Lastly, sometimes the East Antarctic ice sheet’s path to the sea is clogged by mountains or other obstructions. If the sheet stays in one spot for a long time, strong winds and sunlight can evaporate the top layers and reveal much older ice and large meteorite concentrations within it. This way, more than 20,000 samples of rock from unknown sources were collected since 1976.
