Lake Tanganyika

                Lake Tanganyika is an African Great Lake. It is estimated to be the second largest freshwater lake in the world by volume, and the second deepest, in both cases, after only Lake Baikal in Siberia. It had a surface of 32,900 km2 (12,700 sq mi). It is also the world's longest freshwater lake. The lake is divided among four countries – Tanzania, the Democratic Republic of the Congo, Burundi, and Zambia. 
                The major river that flows into this lake is the Ruzizi River, which enters the north of the lake from Lake Kivu. The Malagarasi River, which is Tanzania's second largest river, enters the east side of Lake Tanganyika. The Malagarasi is older than Lake Tanganyika and before the lake was formed directly drained into the Congo river .

Mount Meru

              Mount Meru is an active stratovolcano located 70 kilometres (43 mi) west of Mount Kilimanjaro in Tanzania. At a height of 4,565 metres (14,977 ft), it is visible from Mt Kilimanjaro on a clear day. His caldera has a diameter of 5 km, formed 7800 years ago when the volcano have collapsed after a huge explosion. The last recorded eruption of the volcano occurred in 1910. 
              Mount Meru is the topographic centerpiece of Arusha National Park. Its fertile slopes rise above the surrounding savanna and support a forest that hosts diverse wildlife, including nearly 400 species of birds, and also monkeys and leopards. There are two mountain huts: Miriakamba-hut (2514 m) and the Saddle hut (3500 m).

Kilimanjaro

                Kilimanjaro with its three volcanic cones, Kibo, Mawenzi, and Shira, is a dormant volcano in Kilimanjaro National Park, Tanzania and the highest mountain in Africa at 5,895 metres or 19,341 feet above sea level. Kilimanjaro is a giant stratovolcano. 
                Two of its three peaks, Mawenzi and Shira, are extinct while Kibo (the highest peak) is dormant and could erupt again. The last major eruption has been dated to 360,000 years ago, while the most recent activity was recorded just 200 years ago. Kibo is capped by an almost symmetrical cone with scarps rising 180 to 200 m on the south side. These scarps define a 2.5 km wide caldera. Within this caldera is an inner crater, the Reusch Crater.
