III. Lake Malawi is at the southern end in the Rift Valley.

IV. Lake Victoria, the largest one, is a part of the Rift Valley.

Which of the above statements are correct?

Key Points

• The Great Rift Valley: It is a continuous geographic trench, approximately 6,000 kilometers in length, that runs from the Beqaa Valley in Lebanon which is in Asia to Mozambique in Southeast Africa.
• Formation of Lakes: The Great Rift Valley in East Africa is known for forming a series of lakes, which are collectively known as the Rift Valley lakes.
• Fresh Water Lakes: Most of the lakes in the Rift Valley are fresh water lakes, although some are saline.
• Lake Malawi: It is one of the major lakes in the Rift Valley and is located at the southern end of the valley.

Additional Information

• Great Rift Valley:
  • The Great Rift Valley is a geological and geographical feature running north to south for around 6,000 kilometers (3,700 miles) from northern Syria in Southwest Asia to central Mozambique in East Africa.
  • This continuous geographic trench is a result of tectonic plates moving apart and is home to numerous active volcanoes and hot springs.
  • It is one of the most important and impressive features of the Earth's surface.
• Rift Valley Lakes:
  • The Rift Valley is known for its collection of lakes, which are among the oldest and deepest lakes in the world.
  • These lakes include Lake Victoria, Lake Tanganyika, Lake Malawi, and Lake Turkana, among others.
  • These lakes are of great ecological and economic importance, providing water, food, and transport routes for millions of people.
• Lake Victoria:
  • While Lake Victoria is located near the Rift Valley, it is not technically part of the Rift Valley system. It is primarily situated between the eastern and western branches of the Rift Valley.
  • It is the largest lake in Africa and the world's second-largest fresh water lake by surface area, after Lake Superior in North America.
  • The lake is a vital resource for the surrounding regions, supporting diverse ecosystems and human populations.
• Lake Malawi (Lake Nyasa):
  • Lake Malawi, also known as Lake Nyasa, is the southernmost lake in the East African Rift Valley system.
  • It is the third largest and second deepest lake in Africa and is known for its remarkable biodiversity, including a large number of endemic fish species, particularly cichlids.
  • The lake is a crucial source of freshwater and livelihoods for the people living around its shores.
