Rocks and Weathering
Cycle of Erosion and Deposition What are the
steps in the cycle of erosion and deposition?
Erosion wears down mountains and fills valleys
with sediment
Working together erosion deposition have almost
leveled the land surface

Some Examples of physical weathering aka
mechanical weathering

Chemical Weathering

• Agents include water, oxygen, carbon dioxide,
  living organisms, and acid rain.
• Oxygen causes oxidation example rust
• Carbon dioxide produces weak acid marble and
  limestone
• Living organisms produces weak acids root
  action
• Acid rain

what would happen if a rock cube broke into
smaller cubes.

Which Weathered Faster? Use the data table to
make a double-line graph. What are the axes?
Determine a key and title for the graph. Did
Stone A or Stone B weather faster?

Exploring Earths Surface
Lewis Clarks Journey The route of the Lewis
and Clark expedition crossed regions that
differed greatly in elevation and relief. What
were the highest and lowest points on their route?

Exploring Earths Surface
Landforms Plains, mountains, and plateaus are
three of the many landforms that make up the
topography of Earths surface.

Landform Regions of the United States
Florida The United States has many different
landform regions. Identify Florida on the map.
Classify it by landform region.

Mass Movement
Remember gravity is the force that pulls
everything towards the center of the Earth.
Mass Movement The different types of mass
movement include landslides, mudflows, slumps,
and creep. Match each type of mass movement with
the appropriate diagram.
