Question

suppose earth's landmasses someday all move together again. describe the changes that would occur in earth's oceans and earth's landmasses

Answer 1

It depends the speed of the collision. The higher the speed, the more impact it'll have on the landmass, perhaps forming more mountains. Now, on the landmass, life will struggle at first (depend on location or area where the land mass is at the equator) but will later eventually survive. The climate may be warmer or cooler than usual. On the oceans, damages may occur during the collision. The way certain sea creatures migrate and where schools go, will drastically change directions, changing the long tradition and cycle that it has been going on, and will also change the food cycle, locations where to live, hide, hunt and more.

Answer 2

The Earth's continents are in constant motion.

Step-by-step explanation:

Earth's continents have all collided to form one giant continent at least three times. So, considering this, we can assume that it is possible for it to happen again to form another supercontinent. When continents drift apart from each other, oceans are formed, and when they come together, oceans disappear. This happens because the earth's landmasses sit on moving tectonic plates on the Earth's crust, which is divided into nine major plates that glide over the mantle. The rising and falling of mantle material spreads plates apart, or force them together. Converging land masses can lead to the formation of mountain ranges and volcanoes, also would "squeeze shut" oceans. Separating masses would give way to the formation of massive oceans.
