__**OHIO STANDARDS**__ 9. Identify and describe how freezing, thawing and plant growth reshape the land surface by causing the weathering of rock.10. Describe evidence of changes on Earth’s surface in terms of slow processes (e.g., erosion, weathering, mountain building and deposition) and rapid processes (e.g. volcanic eruptions, earthquakes  and landslides). **__2011 Standards__**
 * __ 2002 Standards __**
 * Benchmark B: ** ** Summarize the processes that shape Earth’s surface and describe **
 * evidence of those processes. **
 * 8. Describe how wind, water and ice shape and reshape Earth’s land **
 * surface by eroding rock and soil in some areas and depositing **
 * them in other areas producing characteristic landforms (e.g., **
 * dunes, deltas and glacial moraines). **
 * Earth’s Surface ** – This topic focuses on the variety of processes that shape and reshape Earth’s surface.
 * 1) ** Earth’s surface has specific characteristics and landforms that can be identified. **
 * 2) About 70 percent of the Earth’s surface is covered with water and most of that is the ocean. Only a small portion of the Earth’s water is freshwater, which is found in rivers, lakes, and groundwater.
 * 3) Earth’s surface can change due to erosion and deposition of soil, rock or sediment. Catastrophic events such as flooding, volcanoes and earthquakes can create landforms.
 * 4) ** The surface of Earth changes due to weathering. **
 * 5) Rocks change shape, size and/or form due to water or ice movement, freeze and thaw, wind, plant growth, gases in the air, pollution and catastrophic events such as earthquakes, mass wasting, flooding and volcanic activity. (Note: The ice movement (above) refers to large bodies of ice, such as glaciers that can break large rock into small ones.)
 * 6) ** The surface of Earth changes due to erosion and deposition. **
 * 7) Water, wind and ice physically remove and carry (erosion) rock, soil and sediment and deposit the material in a new location.
 * 8) Gravitational force affects movement of water, rock and soil.
