Question

take a look at the red sea, which separates northeastern africa from the arabian peninsula. 18. what plate tectonic process is going on in the red sea? 19. give the process another 2 or 3 million years. what will the red sea look like at that time? conclusion now that you have studied the theory of plate tectonics and the major plates that earth is made up of, you should be able to figure out the plate movements of the following areas: circle the set off arrows that best represents the plate movement in the following locations on earth: 1. mid - atlantic ridge a. → ← b. ← → c. no plate boundary 2. himalayan mountain range a. → ← b. ← → c. no plate boundary 3. western south american coast a. → ← b. ← → c. no plate boundary 4. hawaiian islands a. → ← b. ← → c. no plate boundary 5. east african rift a. → ← b. ← → c. no plate boundary now use a moist paper towel to wipe off all the marks on the laminated world map!

Explanation:

1. The Mid - Atlantic Ridge is a divergent plate boundary where plates move apart (← →).
2. The Himalayan Mountain Range is a convergent plate boundary where plates move towards each other (→ ←).
3. The Western South American Coast is a convergent plate boundary with subduction (→ ←).
4. The Hawaiian Islands are formed by a hotspot in the middle of a plate, so there is no plate - boundary interaction relevant here (no plate boundary).
5. The East African Rift is a divergent plate boundary where plates move apart (← →). In the Red Sea, the process is divergence. In 2 - 3 million years, it may widen further as the plates continue to separate.

Answer:

1. Divergence.
2. It may widen further as the plates continue to diverge.
3. b. ← →
4. a. → ←
5. a. → ←
6. c. no plate boundary
7. b. ← →
