2. Weathering
Chemical – includes the effect of weathering on molecules and atoms - oxidation, hydrolysis, and acidification
Mechanical - Mechanical weathering is the process of breaking big rocks into little ones

3. Slow Weathering
Erosion
Drought
Melting Ice Caps

4. Fast Weathering
Earthquakes
Volcanoes
Tornado
Flood Fire

5. Erosion
Wind erosion – wearing away of earth’s surface caused by wind

6. Water erosion – wearing away earth’s surface by water

7. Wind Erosion – Erosion caused by the wind
Sand Arch
Sand Dune

8. Deposition - items carried by streams, winds, or glaciers to the site

9. Weather and Climate
Weather - The condition of the atmosphere at a given time and place,
Weather is measured by temperature, moisture, wind velocity, and barometric pressure.

10. Things used to measure weather
Thermometer – Used to measure temperature
Anemometer – used to measure wind speeds
Barometer – Used to measure barometric pressure

11. Climate
Climate is the average weather usually taken over a 30-year time period for a particular region and time period

12. Weather Map L – signifies a low pressure area
Green – Rain
White – Snow

13. Sources of Water
Ground water – water found beneath the earth’s surface.

14. Surface water – water found on the earth’s surface, this water is replenished by precipitation, this is a natural source of water
Lakes hold most of Earth’s fresh water

15. Unnatural Sources of Water
Unnatural sources of water are sources man has created
Bottled water
Tap water (water that comes out of the faucet)
Distilled (bottled water)

16. Atmosphere – water that comes from the atmosphere, this includes rain, sleet, hail, and snow
