Question

Which statements best describe how the Great Rift Valley in Africa formed? Check all that apply.

The rift valley formed when the crust pulled apart.
The rift valley formed at a divergent boundary.
The rift valley formed similarly to an island arc.
The rift valley formed at a convergent boundary.
The rift valley formed when tectonic plates separated

Answer 1

I believe that it’s the fourth one I could be wrong

Answer 2

The rift valley formed when the crust pulled apart.

The rift valley formed at a divergent boundary.

The rift valley formed when tectonic plates separated.

Step-by-step explanation:

The Great Rifte Valley of East Africa is one of the world's geological wonders, a place where Earth's tectonic forces are currently trying to create new plates, separating them from the old ones. A rifle can be seen as a crack in the Earth's surface that widens over time, or more technically, as an elongated basin, bounded by normal faults that drift sharply in opposite directions.

The process is so well displayed in East Africa (Ethiopia-Kenya-Uganda-Tanzania) that geologists have named the new plate. The Plate of Nubia makes up most of Africa, while the smaller plate that is moving away was called the Somali Plate. These two plates are moving away from each other and also from the Arabic Plate to the north.

We can summarize the formation of the Great Rift Valley in Africa in:

• The rift valley formed when the crust pulled apart.
• The rift valley formed at a divergent boundary.
• The rift valley formed when tectonic plates separated.
