Mount Kilimanjaro is Africa’s tallest mountain, standing at an impressive 19,340.5 feet. It is located in northeastern Tanzania, and as a free-standing mountain, it is not associated with any mountain range. Rather than simply a mountain, Mount Kilimanjaro is actually a stratovolcano, which means that it is a huge volcano. As a stratovolcano, Mount Kilimanjaro is made up of ash, lava, and rock, with large quantities of basalts and andesites. It began to form nearly 750,000 years ago when molten lava erupted through the Earth’s crust and began to push rock and sediment upwards. Mount Kilimanjaro is actually composed of three distinct volcanoes, known as Kibo, Mawenzi, and Shira, with Kibo being the center and tallest of the three.
