Would there be more land if there was more continental crust?

Over millions of years, the mantle cooled. Water trapped inside minerals erupted with lava, a process called “outgassing.” As more water was outgassed, the mantle solidified. read more

Maybe. It depends rather more on things like the average age of the oceanic crust, the average thickness of the continental crust and the existence or not of icecaps. read more

Continental crust is the layer of the Earth that's readily seen from space. It makes up all of the Earth's continents and is much less dense than the oceanic crust. Due to a lower density, this layer of crust is able to float on the surface of the water. read more

Continental crust is the layer of igneous, sedimentary, and metamorphic rocks that forms the continents and the areas of shallow seabed close to their shores, known as continental shelves. This layer is sometimes called sial because its bulk composition is more felsic compared to the oceanic crust, called sima which has a more mafic bulk composition. read more
