Help students learn about the surface of the earth with this fill in the blank (cloze) activity for 2nd and 3rd grade. A great teaching unit on the earth's processes. The surface on earth is always changing. Moving wind, water and plants help to shape and change the earth’s surface. Some of these changes occur very slowly over millions of years. Erosion, deposition and weathering takes many years to wear land away and create many of earth’s land forms like valleys, canyons, deltas, cliffs, shorelines and caves. Other events like earthquakes, volcanoes, tsunamis, and floods happen very quickly, some????mes in just a few hours. These events also shape and change the surface on earth. Earthquakes shake the land and cause damage by cracking the land. Deep inside the earth, there is a lot of hot, melted rock. Some????mes, the melted rock which is called lava will move up through the cracks in earth’s surface and cause lots of damage and changes on the surface of earth. Some processes shape the land quickly and some processes shape the land slowly but the surface of earth is always changing. |
