Weathering, Erosion and Deposition

Weathering Erosion Deposition Water getting into cracks, freezing and breaking rocks apart Waves wearing down rock creating a sea cliff Sea Arch forms from wind and water Flood water pounding against a canyon wall and wearing it down Waterfalls wearing down cliffs Rocks breaking down from wind and rain Azure Window in Malta Arches National Park Rain washing away soil from a hillside Wind blowing sand from on location to another Muddy water being carried away by a fast-moving river A mudslide flowing down a steep hill Sand dunes forming from wind in a desert Rock settling at the bottom of a volcanic mountain after an eruption Waves dropping sand on a beach River deltas form where rivers flow into large bodies of water Glaciers drop rock and sand forming landforms called moraines Layers of sediment forming on the ocean floor Barrier Island forms from sand building up near the coast

Causes of Change Weathering – Break down of rock. Breaks it! Erosion – movement of rock. Moves it! Deposition – settling and layering of rock. Drops it!

Causes of weathering, erosion and deposition Wind Water – rivers, waterfalls, streams, oceans, rain Ice – glaciers Gravity Plate tectonics – Earthquakes and Volcanoes Plants and animals including humans
