Do more meteorites strike the earth between the tropics than outside them?

Best answer

Yes, more meteorites are found to strike the Earth between the tropics than outside them, but this observation is more about the likelihood of finding meteorites than the actual distribution of meteorite falls. Several factors contribute to this phenomenon:

1. Climate: The tropics, especially desert regions like the Sahara, have climates that are conducive to preserving meteorites. The dry conditions reduce weathering and erosion, making it easier to find and identify meteorites long after they have fallen.

2. Visibility: In tropical desert regions, the lack of vegetation and the presence of light-colored sand or rock make dark meteorites much easier to spot. This contrasts with more temperate regions, where meteorites can quickly become obscured by vegetation or buried by soil.

3. Search Efforts: There has been more systematic searching done in some of these tropical desert regions, such as the Sahara and the deserts of Oman, leading to a higher number of finds. These efforts are often driven by the ease of finding meteorites in these areas, as well as by the scientific value of these finds.

4. Collection Bias: The apparent higher number of meteorites in these regions is partly due to a collection bias. Since meteorites are easier to find and preserve in dry, barren areas, more have been collected from these locations. This does not necessarily mean that more meteorites fall in these regions; rather, they are just found more frequently.Meteorites fall randomly across the Earth's surface, and there's no scientific evidence to suggest that the Earth's rotation or the distribution of landmasses causes more meteorites to fall between the tropics.
