Which fault type is found in East Africa’s Great Rift Valley?
How was the Great Rift Valley formed and what landforms are found in this region?
Great Rift Valley formed after a meteor struck the earth and created a large hole. The crevice has been home to a city that is now thriving. A rift is an area of large cracks in the crust of the earth. It is caused by the continental plates separating.
What landforms are found in the region of the Great Rift Valley?
- Tectonic landform.
- Horst and graben.
- Normal fault.
- Propagating rift.
How a rift valley is formed?
A rift valley is a lowland area formed by the interaction between Earth’s plates. A rift valley, also known as rift valley, is a lowland area that forms when Earth’s tectonic plates separate. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.Khordad 25, 1394 AP
Which location is on a major rift valley?
The most famous rift valley is the “Great Rift Valley System”, which runs from the Middle East to Mozambique in south. This area is geologically active and contains volcanoes and hot springs as well as geysers and frequent earthquakes.
Which layer of earth is Plasticlike?
What is the difference between a ridge and a rift?
These two words are almost opposites. A rift can be described as a break, crack or split. A rift is a break, crack, split or fissure. A ridge is a narrow, high elevation such as a narrow hilltop or mountain range.
What causes rifting?
Rifting is caused by hot material from the mantle plume reaching the base of a continental plates and heating up the lithosphere. The uwards movement caused by the plume against the plate can also cause extensional forces that can lead to rifting.
What is one way that continental rifts are similar to mid ocean ridges?
Answer: Both mid-ocean ridges and continental rifts form where two plates are moving apart from each other.Dey 25, 1398 AP
What are the common of rift valleys and oceanic ridges?
Rift Valleys and Ocean Ridges are similar in that they share the same seismic structure, which means that both were created from moving tectonic plates. Furthermore, rift valleys and ocean ridges were the result of two plates, moving away from each other, respectively the continental and oceanic plates.Tir 2, 1395 AP
What are common in the four pictures rift valleys and oceanic ridges?
Answer : What is common in the photos? The formation of a divergent plate boundary. This creates the rift valleys, and oceanic ridges. The four presented pictures are most likely bodies of water that has a tight space of water movement.Esfand 18, 1398 AP
What are the common four pictures?
Answer: Rift valleys and oceanic ridges represents the 4 pictures.Tir 14, 1395 AP
What’s the difference between rift valleys and mid ocean ridges?
A rift valley differs from a mid-ocean in that it is not affected by the tectonic plates. If the border between two continental plates is found, a rift can be described as a real valley. If two oceanic plates begin to move away from one another, a mid-oceanic Ridge is formed. …Mehr 28, 1399 AP
Do divergent boundaries create rift valleys?
Divergent borders within continents initially create rifts which then become rift valleys. The most active divergent plate boundaries are found between oceanic plates, and they exist as mid-oceanic Ridges.
What is the difference between a trench and a rift valley?
A rift valley is an elongate depression which forms at the boundary of a divergent plate (ie. A trench is a long, narrow, steep-sided depression of the seafloor formed where a sub ducting oceanic plate sinks into the mantle causing the seafloor to bend downward like a flexed diving board(Earth, pg316).
Why is the Great Rift Valley the most distinguishing feature of the African continent?
The system of rift Valleys that make up the African continent is a great environment for understanding the evolution of man. For the significant paleoanthropological discoveries made in Ethiopia, Kenya Tanzania, Uganda, Zaire, and Tanzania, the African rifts can be considered the “cradle” of humanity. …
What is the largest rift valley on Earth?
What is the most important physical feature of East Africa?
The Great Rift Valley dominates East Africa’s physical geography. It runs through the region from the north to the south. The rift valleys are characterized by large savannas, such as the Serengeti Plain and large lakes.
How do people in rural areas of East Africa make a living?
Most of East Africa’s population earn their living through agriculture, as the country has a large rural population. The cities are growing at an unprecedented pace due to large families and a shifting population from rural areas to urban.
What is East Africa famous for?
Geographically, the region is well known for its magnificent physical features. These are the two highest mountains in Africa: Mount Kilimanjaro (also known as Lake Victoria) and Mount Kenya (also known as Lake Malawi). The source of the longest river in Africa, the River Nile, is Africa’s largest lake, Lake Nyanza, also known as Lake Victoria.
