Weathering & Erosion

Weathering

8/30 8/31 Forces of Change Phenomenon Evidence for PT Effects Plate Tectonics - Weathering – A process which breaks down rocks Erosion- Human Factors - Volcanism - 1. Fit of Continents 2. Fossil Alignment/Location 3. Sea Floor Spreading The movement of Earth’s plates and the landforms it creates Mountain Building and Earthquakes Creates soil and breaks down mountains

Erosion

8/30 8/31 Forces of Change Phenomenon Evidence for PT Effects Plate Tectonics - Weathering – A process which breaks down rocks Erosion- Ground surface moved from one place to another (wind /water /glaciers) Human Factors - Volcanism - 1. Fit of Continents 2. Fossil Alignment/Location 3. Sea Floor Spreading The movement of Earth’s plates and the landforms it creates Mountain Building and Earthquakes Creates soil and breaks down mountains Coasts Canyons Cliffs caverns

Human Factors

8/30 8/31 Forces of Change Phenomenon Evidence for PT Effects Plate Tectonics - Weathering – A process which breaks down rocks Erosion- Ground surface moved from one place to another (wind /water /glaciers) Human Factors – Entertainment, Urbanization, Mining, Deforestation Volcanism - 1. Fit of Continents 2. Fossil Alignment/Location 3. Sea Floor Spreading The movement of Earth’s plates and the landforms it creates Mountain Building and Earthquakes Creates soil and breaks down mountains Coasts Canyons Cliffs caverns Humans are both Builders AND Breakers of Landforms

Volcanism

8/30 8/31 Forces of Change Phenomenon Evidence for PT Effects Plate Tectonics - Weathering – A process which breaks down rocks Erosion- Ground surface moved from one place to another (wind /water /glaciers) Human Factors – Entertainment, Urbanization, Mining, Deforestation Volcanism – When magma is released to the earth’s surface 1. Fit of Continents 2. Fossil Alignment/Location 3. Sea Floor Spreading The movement of Earth’s plates and the landforms it creates Mountain Building and Earthquakes Creates soil and breaks down mountains Coasts Canyons Cliffs caverns Humans are both Builders AND Breakers of Landforms Islands and Mountains
