CHANGING EARTH TEK 5.7B
What is Erosion? Type of weathering in which surface soil and rock are worn away through environmental interactions.
What are 3 Types of Erosion? Wind Water Ice Strong winds can carry away sand and soil. Fast flowing water can erode soil and small rocks. Liquid water seeps into rock cracks. When the water freezes, it expands and cracks the rock!
What is Deposition? It is the geological process by which material is added to landform or land mass building upon the sedimentary layers.
What type of landforms does erosion create? Delta Canyon Sand Dunes A deep narrow valley with steep sides cut into the Earth by running water. Formed at the mouth of a river that flows into an ocean, estuary, lake, or reservoir. A mound of loose wind blown sand.
