The East African Rift was formed as a result of tectonic processes where the African tectonic plate is splitting into two smaller plates: the Somali Plate and the Nubian Plate. This rifting process began around 25 million years ago and is characterized by volcanic activity and the creation of fault lines as the Earth's crust stretches and thins. Over time, this has led to the formation of a series of valleys, lakes, and volcanic mountains, marking a significant geological feature in East Africa. The ongoing rifting continues to shape the landscape and has implications for seismic activity in the region.

What is it when the earths crust splits apart a ravine called a what valley is formed?

When the earth's crust splits apart and a ravine is formed, it is called a rift valley. Rift valleys are created by the stretching and thinning of the Earth's crust, often associated with tectonic plate movements or volcanic activity. Examples of rift valleys include the East African Rift and the Rhine Valley in Europe.


How was the rifted valley formed?

The rift valley was formed when the continents divided it split open a large area in Africa and formed The Great Rift Valley.


What is the great valley that runs from north to south in east Africa what formed this valley?

I belive it is called the Great Rift Valley


Where are the rift valleys on earth?

The East African Rift Valley is a prominent example of rift valleys on Earth, running through countries like Ethiopia, Kenya, and Tanzania. Another well-known rift valley is the Great Rift Valley in Asia, which extends from Syria to Mozambique. These rift valleys are formed by tectonic plate movements that create deep valleys and high mountains.


Are rift valleys formed by the movement of the earth's crust?

Yes, rift valleys are formed by the movement of the Earth's crust, specifically through a process called tectonic activity. When tectonic plates diverge or pull apart, the land between them can sink, creating a low-lying area known as a rift valley. This geological feature is often characterized by steep sides and can lead to the formation of new geological formations, including lakes and volcanoes. Examples of rift valleys include the East African Rift and the Baikal Rift in Russia.


How did the East Africa rift originate?

The East African rift vally is a landform that occured due to the divergence of the Nubian and Somalian subplates.


Are rift valleys formed from normal faults?

Yes, rift valleys are typically formed by normal faults. In these geological formations, tectonic plates pull apart, causing the land between the faults to sink and create a valley. This process occurs due to extensional forces, leading to the characteristic steep sides and flat floors of rift valleys. Examples include the East African Rift and the Basin and Range Province in the western United States.


The Great Rift Valley of East Africa is an excellent example?

The Great Rift Valley in East Africa is an excellent example of rift caused when the tectonic plates move away from each and the upper crust falls through the gap. The Great Rift Valley is home to many of Africa's deepest lakes.


Which plate boundary causes rifting?

Rift are formed between divergent boundaries, as the plates break apart from each other, a rift is formed between them. Also as they split apart the void between them forms a rift valley. Like the great rift valley in Africa.


How is a suture zone formed?

the rifts didn't developin exactly the same places where Pangaea was first sutured together. for example, the rift that formed the Atlantic ocean was located to the east of the present Appalachian mountains.


What natural feature found in east Africa was crated when tectonic plates puled apart from each other?

The East African Rift Valley was formed at this divergent boundary, located near the Horn of Africa.
