Mantle
Crust
The Atlantic Ocean is growing in size by about one centimeter per year. How does an ocean become larger?
Oceanic plates are moving apart.
The density of the oceanic plates is decreasing.
Increased air temperatures are increasing evaporation.
Trenches are formed by oceanic plates sliding under continental plates.
