The Earth’s surface is constantly changing. Some changes happen very slowly over long periods of time, such as weathering, erosion, and uplift. Other changes happen abruptly, such as landslides, volcanic eruptions, and earthquakes. All around us, we see the visible effects of the building up and breaking down of the Earth’s surface.


Students will understand that volcanoes, earthquakes, uplift, weathering, and erosion reshape the Earth's surface by:
*describing and exlaining how weathering and erosion change Earth's surface.
*describing how the building up and breaking down of the Earth's surface over time creates the various physical land features.
