Is the Serengeti grassland in Africa an extinct crater? Details?

Serengeti Plain is not a crater, but mainly crystalline rocks covered with volcanic ash, accompanied by a large number of granite (hills) exposed from the ground. The narrow areas in the north and west are mainly mountainous areas formed by volcanic eruption. It is adjacent to Ngorongoro Nature Reserve (809,440 hectares) in the southeast. Ngorongoro reserve has the world-famous Ngorongoro crater, which is an extinct crater.

Ngorongoro Nature Reserve (Ngorongoro

protect

Area) is located in north-central Tanzania. 1979 has been declared as a world natural heritage by UNESCO, and is called "the Garden of Eden in Africa". The core of the reserve is the world-famous Ngorogoro Crater, which is the most complete crater in the world, just like a "great basin" embedded in the Great Rift Valley of East Africa. Africans call it Ngorongoro, which means "big hole". The huge crater is a relic of volcanic eruption 8 million years ago, but so far, it has stopped erupting for 250 thousand years. The crater is more than 600 meters deep, with a diameter of about 18 km, a bottom diameter of about 16 km and an area of more than 264 square kilometers. It is also the second largest crater in the world. There are fault lakes such as Eyasi, Maniara and Natron nearby, as well as volcanoes such as Mount Meru and Mount Lungai (active volcano).
