Question

read the passage and look at the picture.
in iceland, parts of the mid - atlantic ridge are above sea level. the thingvellir rift valley is one example. this rift valley began to form as the north american plate and the eurasian plate moved away from each other. in this picture, you can see the gap that formed during a major plate movement along the rift. gaps such as this form when the two plates move apart, creating a large crack in the crust. the last time this happened in the thingvellir rift valley was in the spring of 1789. since then, a walking path was built along the rift valley to allow park visitors to walk along the rift.
complete the sentence.
the thingvellir rift valley formed at a ______ boundary.
convergent
divergent
transform

Explanation:

A divergent plate boundary occurs when tectonic plates move away from each other, which creates rift valleys like the Thingvellir Rift Valley as described, where the North American and Eurasian Plates moved apart. Convergent boundaries involve plates colliding, and transform boundaries involve plates sliding past each other, neither of which form this type of rift valley.

Answer:

divergent
