Artificial sweeteners are just one type of sugar substitute. The chart lists some popular sugar substitutes and how they're commonly categorized.
The Lithosphere The part of the land that is moving is the Earth's surface called the lithosphere. The lithosphere is made up of the Earth's crust and a part of the upper mantle. The lithosphere moves in big chunks of land called tectonic plates.Some of these plates are huge and cover entire continents.he lithosphere is made up of the Earth's crust and a part of the upper mantle.

The Continental Slide. New crust is continually being pushed away from divergent boundaries (where sea-floor spreading occurs), increasing Earth's surface. But the Earth isn't getting any bigger. What happens, then, to keep the Earth the same size? The answer is subduction. In locations around the world, ocean crust subducts, or slides under, other pieces of Earth's crust. The boundary where the two plates meet is called a convergent boundary. Deep trenches appear at these boundaries, caused by the oceanic plate bending downward into the Earth. Deep below the Earth's surface, subduction causes partial melting of both the ocean crust and mantle as they slide past one another.
