________________________________________________________________________________________________________________________________________________________

Text:We could also say that erosion is an antonym for ___________________. There are processes like _________________ and uplift that build up the Earth, but processes like erosion wear down the surface of the Earth. When these two forces are equal (the forces of uplift/deposition and erosion), the Earth is said to be in _____________________ ________________________.

The force of _________________ drives all erosional processes. As tectonic forces build mountains, erosion powered by gravity wears them down. Nearly all erosion starts with earth materials at a high elevation and moves them to a lower elevation. Wherever the ground is too steep for friction to hold rock and soil in place, there is danger that it will move downslope. _____ _________________ is the motion of soil or rock down a slope without the influence of running water, wind, or glaciers.

Sometimes there is the rapid, down-slope movement of rock and soil known as a _____________. Similar to this, an _________________ is the rapid, downhill movement of snow, similar to a landslide, that occurs on a steep slope. Large quantities of rock can be carried down by avalanches. Some mountain valleys show evidence of avalanches where trees have been

uprooted by slides in the past. Not all mass movement is sudden, however. Perhaps the most common form of mass movement is referred to as soil creep. This is the slow progression of soil down a slope due to the force of gravity (and usually other things like water, vegetation, and type of soil).
