Impact craters are caused when the planet is struck by solid objects travelling at high velocity, producing shock waves and the compression of material to form a circular crater.
Earth is bombarded every year by rocky debris, but the rate of incoming meteorites can change over time. Finding enough meteorites scattered on the planet's surface can be challenging, especially if you are interested in reconstructing how frequently they land.
A team of experts from Botswana, South Africa, Finland and the United States of America recovered a fresh meteorite in Botswana’s Central Kalahari Game Reserve (CKGR).
