Question

Известно что озеро танганьика вытянуто с севера на юг на 650 км а озеро ньяса на 580. почему котловина этих озёр имеет вытянутую форму

Answer 1

Эти озера имеют тектонический тип образования и заполняют тектонические разломы, которые имеют вытянутую форму.

Answer 2

The Shape of Lake Tanganyika and Lake Nyasa

Lake Tanganyika and Lake Nyasa (also known as Lake Malawi) are both located in the East African Rift Valley. Lake Tanganyika is elongated from north to south, stretching for about 650 kilometers, while Lake Nyasa is elongated from north to south for about 580 kilometers. The elongated shape of these lakes is due to the tectonic activity in the region and the geological processes that have shaped the East African Rift Valley.

The East African Rift Valley is a result of the divergent movement of tectonic plates, which has caused the Earth's crust to stretch and thin. This stretching and thinning of the crust has created a series of deep rifts or valleys, including the East African Rift Valley. The rift valley is characterized by steep cliffs, escarpments, and a series of lakes, including Lake Tanganyika and Lake Nyasa.

The elongated shape of Lake Tanganyika and Lake Nyasa can be attributed to several factors:

1. Tectonic Activity: The East African Rift Valley is an active tectonic zone, where the African Plate is splitting apart. This tectonic activity has caused the Earth's crust to stretch and thin, resulting in the formation of the rift valley and the elongated shape of the lakes.

2. Faulting and Graben Formation: The rift valley is characterized by a series of faults and grabens, which are elongated depressions bounded by faults. These faults and grabens have influenced the shape of the lakes, causing them to be elongated in the north-south direction.

3. Erosion and Sedimentation: Over millions of years, erosion and sedimentation processes have also played a role in shaping the lakes. Rivers and streams flowing into the lakes have carried sediment and eroded material, which has accumulated at the northern and southern ends of the lakes, further elongating their shape.

It is important to note that the information provided above is based on general knowledge about the formation of rift valleys and the shape of lakes in tectonically active regions. For more specific and detailed information, it is recommended to consult geological studies and research papers on the subject.
