PowerPoint Presentation:

erosion weathering & 5 th Grade Science Kaly Shingleton

Standards:

erosion weathering & S5E1. Students will identify surface features of the Earth caused by constructive and destructive processes. b. Identify and find examples of surface features caused by destructive processes. • Erosion (water—rivers and oceans, wind) • Weathering • Impact of organisms • Earthquake • Volcano M5D1. Students will analyze graphs. a. Analyze data presented in a graph. b. Compare and contrast multiple graphic representations (circle graphs, line graphs, line plot graphs, pictographs, Venn diagrams, and bar graphs) for a single set of data and discuss the advantages/disadvantages of each. c. Determine and justify the mean, range, mode, and median of a set of data. Standards

PowerPoint Presentation:

There are many factors that can cause landforms to change shape overtime. water wind ice heating cooling Table of Contents Next Slide

PowerPoint Presentation:

These factors that change the appearance of our landforms are called: water wind ice heating cooling Weathering Table of Contents Next Slide

PowerPoint Presentation:

Weathering is the process of breaking and changing of rocks, soil, sand, and sediment over time. Table of Contents Next Slide

Weathering and Erosion:

Weathering and Erosion Particles are broken down, which is known as weathering , but what is it called when they’re taken away? Erosion Table of Contents Next Slide

PowerPoint Presentation:

Weathering and Erosion change the physical and chemical appearance of our landforms. water wind ice Weathering & Erosion What are some agents of weathering & erosion? heating cooling & Table of Contents Next Slide

water wind ice Weathering & Erosion heating cooling & types Click on a type of erosion and find out more! Done! Ready to see more of the presentation! Examples Desert Storms (Creating Sand dunes) Rivers Expansion of particles within rocks Lakes Streams Frozen water expands cracks within rocks The cooling of heated particles leaves cracks in rocks Wind Storms Table of Contents

PowerPoint Presentation:

wind In wind erosion, particles of sand are picked up by the wind and dropped. This can cause sand dunes . Back to all Agents

PowerPoint Presentation:

water The greatest cause of erosion is running water. Water flowing over rocks can weather away the surface and carry particles downstream. Back to all Agents

PowerPoint Presentation:

ice Ice can create cracks within rocks and glaciers Back to all Agents

PowerPoint Presentation:

heating cooling & Water gets in the cracks of rocks. The freezing action of water can expand the cracks of rocks, causing them to break. Also, particles within rocks expand when heated, and contract when cooled, causing movement within the rock. Back to all Agents

Long Island Long Island, NY is an example of weathering. It was formed by glaciers overtime. Table of Contents Next Slide erosion weathering &

Weathering Erosion Forces that are changing the shape of our world. Wearing down natural land forms such as mountains, streams, and valleys. The process of breaking and changing of rocks, soil, sand, and sediment over time. The carrying away of weathered down rocks, soil, and sand.
