A rift boundary is a divergent boundary, where two plates of the earth's crust are moving away from each other. Divergent boundaries occur at mid-oceanic ridges on the sea floor, but usually the term rift is used to describe divergent boundaries on the land. The best known one is in eastern Africa.
What else can I help you with?
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.
What kind of valley where plates move apart?
A rift valley is formed when tectonic plates move apart, creating a gap in the Earth's crust. This process is often associated with divergent boundaries where new crust is formed as magma rises to fill the gap. Rift valleys can be found on land or under the ocean.
Types of landforms formed by divergent boundaries?
Divergent boundaries can create landforms such as rift valleys, mid-ocean ridges, and volcanoes. Rift valleys are formed on continents when tectonic plates pull apart, creating long, narrow valleys. Mid-ocean ridges are underwater mountain ranges that form when new oceanic crust is created as plates move apart. Volcanoes can also form along divergent boundaries as magma rises to the surface through the newly formed crust.
At which type of plate boundary does rift-volcanism occur?
Rift volcanism occurs at divergent plate boundaries, where tectonic plates move away from each other, causing magma to rise to the surface and create new crust as it cools and solidifies. This process is often associated with the formation of mid-ocean ridges and rift valleys.
What is it called when the Earth's crust splits apart and a valley is formed that has steep and narrow sides and a flat floor?
This process is called rifting, and the valley formed is known as a rift valley. Rift valleys are typically formed along divergent plate boundaries where tectonic plates are moving away from each other, causing the crust to stretch and fracture.
Are rift valleys made by convergent boundaries?
No, rift valleys are typically formed by divergent boundaries, where tectonic plates are moving apart. As the plates separate, the Earth's crust stretches and breaks, creating a depression that forms the rift valley. This process can eventually lead to the formation of new ocean basins.
What kind of landforms are formed at divergent plate boundaries?
Mid Ocean Ridges and Rift Valleys.
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 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.
What landforms form by divergent boundaries?
Divergent boundaries can create mid-ocean ridges and rift valleys on land. Mid-ocean ridges are underwater mountain ranges where new oceanic crust is formed, while rift valleys are elongated depressions on land where tectonic plates are moving apart.

What type of plate boundary forms rift valleys?
A divergent plate boundary.
How are the movement of plates at divergent boundaries and at transform boundaries?
They both have a Rift Valley.

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.
