Final answer:
Meteorites of primitive material are important for studying the early Solar System. They have been found in Antarctica due to the motion of ice and the concentration of meteorites over time.
Step-by-step explanation:
Meteorites of primitive material are considered more important than other meteorites because they provide valuable information about the early Solar System and the origins of life. These meteorites contain unaltered components that have not undergone significant geological processes, making them valuable for studying the composition of the early Solar System.
Most of these meteorites have been found in Antarctica due to the unique geological and environmental conditions. The motion of ice in Antarctica buries and carries meteorites, concentrating them in certain areas over a long period of time. Once the ice wears away, the meteorites become exposed on the surface, making them easier to spot. Over ten thousand meteorites have been recovered from Antarctica, greatly contributing to our understanding of the early Solar System.
