Why do most meteorites strike Antarctica?

Answer 1

because Antarctica is so cold, it is able to preserve/ keep so many fossils. if it was hot, most of them would've dissolved =)

No. The animals did not live in frigid areas. What became Antarctica was part of the continent of Pangaea, and lay further North, though extending nearly Pole to Pole. The dinosaurs lived on the warmer parts of that.

Answer 2

Antarctica has received no more or less meteorite falls than any other continent on earth, as meteorite falls occur sporadically and can fall virtually on any part of the earth. What makes Antarctica special is several factors. Firstly, the white ice contrasts any rocks that may be lodged in it. Think about it, in your life, you may have walked over many meteorites and never knew because it was surrounded by other rocks, soil, regolith and vegetation. The ice sheets of Antarctica are flat, white and devoid of anything that could prevent you from seeing a stone. They have also existed for a very long time, capturing any space debris and preventing them from being washed away like other terrestrial environments would with rivers, landslides etc. Secondly, Antarctica is cold and very sterile, perfect conditions to preserve meteorites (which are often rich in iron) from rusting or eroding away. Because of this, there have been many scientific expeditions to Antarctica to recover meteorites because they are easier to recover there, and they are also exceptionally clean, which means their analysis will not be effected by any terrestrial impurities like soil.

Answer 3

First, you can find them more easily due to the colour difference between the clear ice and snow and the dark-coloured meteorites. There's also a process by which meteorites are collected in the ice, particularly in blue ice fields. These blue ice fields are pushed against obstacles such as nunataks as the ice migrates, and then the katabatic winds erode the upper layers of the ice and the meteorites become exposed.

The major benefit of the Antarctic meteorites is that they are extremely well-preserved and mostly uncontaminated. The time a meteorite has been on Earth ranges from very recent to a couple of hundreds of thousands to as much as two million years. Most meteorites weather quickly under the oxidizing environment of the Earth. However some meteorites fall at more fortuitous locations (such as the ice fields of Antarctica) and are preserved.

Answer 4

Given the general physicality of 98% of the Antarctic continent -- ice -- meteorites may be easier to spot/ find/ locate, given the high visual contrast between ice and meteorites.

Answer 5

some meteroties might like Antarctica so it strikes it, becqause we gotta admitt Antarctica is quite beautiful. and so are you !
