2. The Earth’s surface is always changing!

8. The breakdown of the Earth’s crust into smaller pieces.

9. What evidence of weathering do you see in this picture?

11. Why wasn’t this mass of land weathered away?

12. Describe how ice/heat cause weathering?

13. PAMUKKALE, WHICH MEANS "COTTON CASTLE" IN TURKISH, IS FOUND IN THE MOUNTAINS OF TURKEY. IT MAY RESEMBLE A GLACIER, BUT THE SITE IS ACTUALLY BATHED IN HOT WATER. THE MINERAL-RICH WATERS OF THE AREA'S HOT SPRINGS HAVE OVER TIME FORMED DAZZLING WHITE LIMESTONE TERRACES.

14. The process of water, ice, wind or gravity moving fragments of rock and soil. What evidence of erosion do you see in this picture?

15.  Erosion carves the Earth's surface creating canyons, gorges, and even beaches. What do you think has caused this rock to look this way?

16.  As the wind blows it picks up small particles of sand/sediment and blasts large rocks with the abrasive particles, cutting and shaping the rock.

18.  runoff, rivers and, streams 1) 2) 3)

20. This simple animation provides you with a visualization of how the Colorado River has "downcut" into the rock layers of the Grand Canyon. How long it took to carve the Grand Canyon is debated by geologists. Some estimates are between 6 and 8 million years, which is very recent by comparison. Canyons are large valleys created by a river or stream.

21. Glaciers wear down the landscape; by picking up and carrying debris that moves across the land along with the ice.

22. Glaciers can pick up and carry sediment that ranges in size from sand grains to boulders bigger than homes !!! Moving like a conveyor belt and a bulldozer, a single glacier can move millions of tons of material!

24. Creep, Slump, Landslides, Mudslides, and Avalanches. These are examples of mass movement (or called mass wasting) SlowerFaster

28. Rock particles that are picked up and transported during erosion will ultimately be deposited somewhere else  Together, Erosion and Deposition build new landforms.  Deltas  Canyons  Meanders  Floodplains

29.  Where rivers meet the ocean is called the mouth of the river.  Soil and dirt carried by these rivers is deposited at the mouth, and new land is formed.  The new, soil-rich land is known as a Delta

30. delta – a fan shaped depositional feature, formed when a load filled stream/river slows, as it enters a larger body of water.

31. alluvial fan – a fan shaped depositional feature, formed when a fast moving mountain stream flows onto a flat plain.

32. Meandering streams wander side to side as they constantly seek out the lowest elevation. This constant motion creates a series of S-shaped “loops”.

33. flood plain – the area along a river that contains rich, fertile soil due to periodic overflow from a stream/river.

34. First, Remember: Weathering is the breaking of a rocks into smaller pieces. Erosion is the movement of those pieces from one place to another! Now Let’s Experiment! Make sure your name is on your lab paper. 8 min per station, 3 stations. Turn it in for your application assessment on weathering.
