Great Rift Valley: Earth's tectonic forces are presently trying to create new plates by splitting apart old ones; a fracture in the earth's surface that widens over time; located in East Africa (Ethiopia-Kenya-Uganda-Tanzania); Nubian Plate makes up most of Africa & the smaller plate that is pulling away is the Somalian Plate; they are both moving away from the Arabian Plate to the north
In the ancient East African Rift at a place known to the local Maasai people as the Mountain of God,Oldoinyo Lengai spews forth carbon dioxide lavas called carbonatites. The carbonatites line the volcano's flanks like snowballs. Oldoinyo Lengai is the only place on Earth where carbonatites currently erupts and where carbon dioxide from a volcano doesn't vanish into thin air as a gas.
