Plate Tectonics Picture. Biosphere: Erosion. Erosion is the process that breaks things down.
As far as we're concerned, erosion is the breakdown of the continents and the land around you. The overall effect of breaking down and weathering the land is called denudation. Denudation is the process of erosion. In nature, large things are broken down into smaller things. Weathering national geographic. Weathering is the breaking down or dissolving of rocks and minerals on Earths surface.
Water, ice, acids, salt, plants, animals, and changes in temperature are all agents of weathering. Once the rock has been broken down, a process called erosion transports the bits of rock and minerals away. No rock on Earths surface is hard enough to resist weathering. Together, the processes of weathering and erosion carved the Grand Canyon, in the U.S. state of Arizona. Earthquakes Video. Volcanoes WizKids. Volcanoes (Volcanoes are not associated with weather, but instead are natural disasters.)
What is a volcano? A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth.
