What may happen if the entire crust of earth was one plate? erosion would change the color of earth's surface. earth would be cold due to less carbon dioxide. volcanoes and earthquakes will destroy life on earth. chemical weathering would not create unique landscapes.

Over millions of years, continents drift across Earth's surface, going from one climate zone to another. Without plate tectonics, Earth would not have its diverse geography, which provides a wide range of habitats. Plate tectonics is also responsible for hydrothermal vents on the ocean floor
