Agents of Erosion Review
BAY
1. What sediments look like after they have been transported by gravity alone. Describe/sketch
their shape. Are they sorted or unsorted? Label where you would find them on the diagram.
8. Label the delta. Add in the names of sediments from pebbles to clay AND sketch it as seen from
the side.
2. Draw on the diagram what a sediment would look like when it fell into the stream in the
mountains and what it would look like when it got to the ocean. (Label them 2A and 2B)
Delta Side View:
3. Label where the fastest overall velocity of the river would be. Why did you choose that spot?
4. Label where the discharge of the river would be the greatest.
9. Sketch in where sand would collect due to longshore transport, include an arrow for the
direction of movement based on the features you sketched in.
5. Label where you would find a V shaped valley and U shaped valley.
10. Label the features made by wind and draw an arrow to show what direction the wind was
blowing to create them. If we could zoom in on this area, sketch what a rock exposed to wind
abrasion from one direction from a long time would look like (before and after the abrasion).
6. On a meander, label: Fast velocity, slow velocity, erosion and deposition.
Rock/Ventifact Before:
7. Draw a line A-B across a meander and sketch a profile of what this area would look like.
11. After doing the back of this, label areas where you would see weathering types X, Y and Z and
where you would find a terminal moraine.
Rock/Ventifact After:

Soil Review
Number the pictures below 1-4 with 1 being the oldest and 4 being the most recent. Then labe the horizon with the most organic
matter. Is this an example of residual or transported soil?
Bonus Opportunities:
-adding the following concepts/processes to the first diagram:
-three different examples of how gravity alone transports sediments and what they are/mean
- the formation of sea arches and stacks
-what the shore and continental shelf looks like, where a turbidity current would happen and how
sediments settle after one
-bringing in actual samples that show the progression of sediments transported for a short->long time
-bringing in an original picture you took of a meander showing erosion/deposition in the appropriate spots
-bringing in a picture of a feature formed by wind and telling your teacher how it was formed
-a Google Earth tour you created to show real life examples of features formed by gravity, water, waves and wind
erosion
-any ideas you have that are approved by your teacher
