Changing Earth’s Surface

Cycle of Erosion and DepositionWhat are the steps in the cycle of erosion and deposition?

Rocks and Weathering

Forces of Physical Weathering

Rocks and Weathering

Chemical Weathering•Oxygen causes rust to form which makes rocks soft and a reddish brown color.•Carbon Dioxide creates carbonic acid which weathers marble and limestone.•Living organisms can produce weak acids.•Acid rain is rain combined with pollutants which speeds up weathering.

Weathering and Surface AreaThe diagram shows what would happen if a rock cube broke into smaller cubes. Which rock would have a higher weathering rate?

Rocks and Weathering

What does permeable mean?

•How does that change weathering rates?

Rate of Weathering•Rate of weathering depends on CLIMATE and TYPE of ROCK.•Chemical weathering occurs faster in climates that are hot and wet.

Water Erosion

Factors Affecting RunoffWhat are the five main factors affecting runoff, and what are some examples?

How can we prevent Runoff?Planting vegetation, decreasing slopes, decreasing size of areas that are just dirt.

Stream FormationWhich arrows indicate the direction of sheet erosion? Where are rills and gullies in the picture? Streams and rivers? Tributaries?

Make sure you know the vocab that is in BOLD.

Water Erosion

Oxbow LakesWhat happens in step 4 of this diagram to form an oxbow lake?

What does an Oxbow Lake look like?

Water Erosion

Alluvial Fan•A wide sloping deposit of sediment formed when a stream leaves a mountain range.

Water DepositionDeposition creates landforms such as the Mississippi River delta.

Florida Landforms

Florida LandformMost of Florida is relatively flat, but over time the changing sea levels have shaped a varied landscape.
