Question

what is the name of the supercontinent believed to have existed approximately 335 million years ago?○ gondwanaland○ pangaea○ laurasia○ rodiniaa mid-ocean ridge is an example of a *○ convergent boundary○ divergent boundary○ transform boundary○ hot spot

Explanation:

For the first question: Pangaea is the supercontinent that formed around 335 million years ago, later breaking into smaller landmasses. Gondwanaland and Laurasia were fragments of Pangaea, and Rodinia is an older supercontinent that existed over 1 billion years ago.
For the second question: Mid-ocean ridges form where tectonic plates move apart, which defines a divergent boundary. Convergent boundaries involve plates colliding, transform boundaries involve plates sliding past each other, and hot spots are stationary magma plumes independent of plate boundaries.

Answer:

1. Pangaea
2. divergent boundary
