Question 32

In this stage, the rift valley is formed while the continent is begins to split. However, before that the ocean basin is experience the rifting and also volcanic at the beginning. The movement that appears in this stage is the uplift of the bottom part of the ocean.

Answer 32

Embryonic

Question 33

In this stage, the movement that appears and happens is the subsidence of the ocean bottom and it will spread. The subsidence and the spreading will create the deviation of the continent. And because of the diverge, the seafloor basalt will be created.

Answer 33

Juvenile
