Ocean features are formed by the movement of plate tectonics. The floor of the ocean can spread or converge and magma can cause new crust.Ocean Floor Overview The ocean floor, or seabed, is a term used to describe the top layer of oceanic crust found on the bottom of the ocean just abo...

This process of rock being “swallowed” or forced back into the earth’s mantle is called subduction. During subduction, as a plate dives into the depths, we think part of it finds its way back to the surface in the form of volcanoes.The theory of plate tectonics and the discovery of ...
aForty years after the discovery of seafloor spreading and the acceptance of the theory of plate tectonics, important gaps remain in our understanding of the pattern of convection that drives the motions of the plates, leading to earthquakes, tsunamis and volcanic eruptions. There are still many ...

It's hard to know anything for certain about the early history of Mars, but educated guesses can be made thanks to the fact that Mars doesn't have plate tectonics. In fact, whileMars and Earth have a few things in common, this isn't one of them. On Earth, the ground is constantly...

Loam is generally considered the ideal soil—equal amounts of sand and silt size with a lesser amount of clay. Sand gives soil volume and porosity; silt gives it resilience; clay provides nutrients and strength while retaining water. Too much sand makes a soil loose and sterile; too much si...
