If you compare the earth to an egg, the shell on an egg is like the crust on the earth. This causes the sharp edges of the rocks to get knocked off that is why river rocks are so smooth beach pebbles look polished. In practice, the implementation of soil conservation tends to be standards-based in view of the prevailing uncertainty, whereas economic analysis tends to assess the efficiency implications. The future of Flash on mobile devices and tablets is not in the web-browser though but in the appstore. Ephemeral gully erosion (26 images) Ephemeral gullies are shallow gullies that are very much wider than deep.

Soil erosion is a form of soil degradation on agricultural land. Precipitation / Floods: heavy rain can cause floods which move break rocks Broken glass is tumbled on the beach and worn smooth by the action of the waves. The mass wasting which produced the dendritic rill and gully pattern at the margin of steam explosion pits (Figure 3) resembles the dendritic pattern formed on december 20, 1980, at Lake Peigneur, Louisiana. When volcanoes erupt and the liquid rock comes up to the earths surface, then new igneous rock is made. An entire landscape has been subjected to various agents of sculpture including wave erosion, jetting steam, mass wasting, rill and gully erosion, sheet flooding, and mudflow erosion.
