If a large meteorite lands in water, there will be tsunamis following it then flooding and more inland destruction. the smallest pea-sized ones won’t matter much but if the meteorites are the size of mountains, it will probably take out a whole city and its surrounding areas, not just a household pet...we won’t be around to mourn its loss. We will all go! |
