What are some examples of landforms? • Mountains • Deserts • Dunes • Valleys • Rivers • Plains • Shore lines
How are landforms created? • Erosion: • Weathered particles are picked up and moved • Deposition: • Sediment is placed in a new location
Erosion occurs in 3 ways • Water • Rainwater erodes sloping land • When it reaches river, deposits those sediments • Wind • Carries small particle for long distances • Pushes large particles along ground • Ice • Transports rock and soil as it moves and melts
Force of gravity • Moves water down a slope • Niagara falls erodes the rocks underneath it • Mass wasting • Downhill movements of rock and soil • Landslides in California • Rockfalls/rockslides • Mudflow • creep
Paraphrase this sentence: In a rockfall, individual blocks of rock drop suddenly and fall freely down a cliff or steep mountain.
For lab • Work with your group to figure out how to use soil, water, and trays to test the effects of rainwater on sloping land. • Write a hypothesis to test. • Write down your procedure. • When finished, place papers in center of table. Choose one team member to get me for check. • Carry out experiment.
