Answer:
The plates will collide in 50,000,000 years.
Explanation:
The tectonic plates are constantly moving. Their movement results in some of them to collide, thus to form convergent plate boundaries. In this case, we have two plates that are relatively far away and the movement is about the average. In order to find out how many years will be needed for the plates to collide we need to:
- convert the km into cm
- divide the distance (in cm) between the plates with the rate of movement of the plate
1 km = 100,000 cm
100,000 x 1,500 = 150,000,000 cm
150,000,000 / 3 = 50,000,000 years
We get a result of 50 million years, meaning the plates will collide in this much time, which in geological terms is actually not that long.
The conterminous United States predominantly lie in the zone of the westerly winds. Most of the territory of the United States lies in there territory. USA is in the northern hemisphere, and the territory is right where the coriolis effect takes place, so the winds go in eastern direction because of this natural phenomenon, so we have winds moving from west to east, thus westerly winds.
The conclusion is that the pillar corals are heavily dependent on the sunlight in order to survive and flourish.
In warm waters, other organisms compete with them, and the pillar corals are out-competed, so the sunlight is blocked, partially, or totally, so they are not able to function.
Because they are not able to function, the pillar corals are dying out, thus living space for other organisms to take their niche in the ecosystem.
