What would the world be like if there was no plate tectonics?

Answer 1

It is most likely that the earth would be a water world without plate tectonics.

There would be no continents or land left if the continents were entirely eroded into the oceans, which make up two thirds of the world and have an average depth greater than that of the continents.

The continents are eroding; if plate tectonics hadn't been in place to push them upward, the erosion would have caused the continents to vanish beneath the ocean's surface.

Without plate tectonics, Earth's surface would lack major geological features like mountains and ocean trenches. Limited nutrient cycling would impact ecosystems, and the absence of volcanic activity would alter the atmosphere. Climate regulation and the distribution of minerals would be different.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
