Here is a power point with over 100 slides and 6 different lessons including: Earth's Layers and soil, Erosion and Weathering, Volcanoes, Earthquakes, Rocks and Minerals, and Fossils and Dinosaurs. I have included many colorful images and photos as well. An entire, huge unit all in one power point! Don't forget to stop by my store, check out the merch, and give me a rating. Thank you!
