Rift valleys form through divergent plate tectonics, where two continental plates move away from each other.
One of the best land examples is the great African Rift Vally in East Africa
The primary cause of rift valley formation is the movement of tectonic plates. When plates in the Earth's crust pull apart, it creates a rift where the crust thins and sinks, forming a valley. This process can occur on a large scale, such as the East African Rift Valley, or on a smaller scale in other regions.
A rift valley forms when the lithospheric stretches, tension stress occurs, causing rock to pull apart, break, and form normal faults.s the hanging wall of a normal fault slide down the footwall, a long, flat, narrow rift valley forms.

What is it called when the crust splits and a valley is formed?
When the crust splits and a valley is formed, it is called a rift or a rift valley. This process commonly occurs as a result of tectonic plate movements and can lead to the formation of new land features such as mountains and valleys.
How did the African Rift valley form?
The African Rift Valley formed due to tectonic movement where the African Plate is splitting apart. This process is creating new divergent plate boundaries, causing the land to weaken and the crust to spread, resulting in the formation of the Rift Valley.
Where does a rift valley form at?
A rift valley forms at divergent plate boundaries where tectonic plates are moving apart. As the plates separate, they create a gap in the Earth's crust that can lead to the formation of a rift valley. An example of a rift valley is the East African Rift in Africa.
Is narmada valley a rift valley?
No, the Narmada Valley in India is not a rift valley. It is formed by a fault line that runs along the Narmada River, resulting in a valley with distinct geological features. Rift valleys are formed by the stretching and pulling apart of the Earth's crust, which is not the case for the Narmada Valley.
What is the primary process involved in the formation of magma at a rift?
Decompression melting of extremely hot mantle rock as it rises toward the surface.
What type of plate movement might cause a rift valley to form?
Divergent plate movement, where tectonic plates move away from each other, can cause a rift valley to form. As the plates move apart, the lithosphere thins and cracks, creating a depression which eventually results in the formation of a rift valley.
What causes a rift valley?
A rift valley was caused by tectonic plates moving against each other. This usually occurs during the formation of mountains.
What motion of the sea floor is responsible for the formation of the mid Atlantic ridges rift valley?
According to scientists, the process associated with seafloor spreading is responsible for the formation of the mid Atlantic ridges rift valley.
What is it called when the crust splits and a valley is formed?
When the crust splits and a valley is formed, it is called a rift or a rift valley. This process commonly occurs as a result of tectonic plate movements and can lead to the formation of new land features such as mountains and valleys.
A rift valley is evidence of which kind of plate boundary?
A rift valley is evidence of a divergent plate boundary, where tectonic plates are moving away from each other. This movement creates a gap that can lead to the formation of a rift valley as the lithosphere is pulled apart.
A rift valley is evidence of which plate boundary?
A rift valley is evidence of a divergent plate boundary, where two tectonic plates are moving away from each other. This movement creates a gap in the Earth's crust, resulting in the formation of a rift valley.
How did the African Rift valley form?
The African Rift Valley formed due to tectonic movement where the African Plate is splitting apart. This process is creating new divergent plate boundaries, causing the land to weaken and the crust to spread, resulting in the formation of the Rift Valley.
How do you use rift valley in a sentence?
I live in a rift valley! Before today, I was unaware that I am a Rift Valley Dude.
Which formation occur when a portion of crust become lowered in a long line?
rift valley
Which formation occurs when a portion of the crust becomes lowered in a long line?
rift valley
How was the Eastern African Rift Valley formed?
The Eastern African Rift Valley was formed by tectonic plate movement where the African continent is splitting apart. This process is known as continental rifting, which causes the Earth's crust to stretch and thin, leading to the formation of a rift valley. The rift valley in Eastern Africa is a classic example of this geologic phenomenon.
What are some examples of a rift valley?
narmada valley is an example of a rift valley
