Models & Maps
In the stream table experiment, which of these can increase the amount of erosion and deposition?
A. Use less water.
B. Use more water.
C. Make the slope flatter.
B. Use more water.
The more water added to our stream table, the more effect it had on the sand, making our canals increase in size and amount.
True or False?
Water flowing through channels with steep slopes causes more erosion.
True
What is this?
A fan shaped deposit at the mouth of the river.
True or false: Erosion takes a short amount of time to occur.
False
A nearly level area that has been listed above the surrounding area is called a...
plateau
How are models and maps different? The same?
Different: Maps are 2-D at a birds eye view, and contains a map key. Models are 3-D(meaning ALL views and angles), can be viewed from all angles, and are not easy to transport.
Similar: They both represent a real thing, and are both smaller or larger version of a real object.
What is a grid?
What is erosion?
The wearing away of earth material.
What is a channel?
The path a stream follows.
A flash flood occurs when there is what kind of rainfall?
A. Normal rainfall
B. Heavy rainfall
C. A tornado
D. Snow
B. Heavy rainfall
Which material was deposited first in our models, and WHY?
The sand because it was heavier than the clay.
Small particles usually take longer to settle!
Rocks in a river would settle before sand or pebbles.
What does a cartographer do?
A person who makes maps.
What is a meander?
A curve or loop in a river.
What is the shape of a delta called?
Alluvial fan
_____is the limit or border of an area.
Boundary
Why are keys important on a map?
It explains what the symbols on the map mean, and allows you to make sense of the map.
What were the different ways that we utilized the stream tables, and what did it change in all of them?
-flat ground
-standard water source
-flood water source
-added red dye
Define sediments:
Small bits of rock, shell, dead plants, that is transported by wind, rain, or ice.
What is the difference between erosion and DEPOSITion?
Erosion is the wearing away of earth material, and deposition is the process by which eroded materials settle out in another place.
What kind of scientist gathers information about the shape of land features?
Surveyor
Name three different types of models we created of the Grand Canyon using our stream tables. (What did we do to change the outcome of our stream tables?)
Standard hole water source, flood hole water source, sloped basin, red food dye.
What is a levee?
a natural or artificial wall of earth material along a river that keeps the land from being flooded.
What is deposition?
The process by which eroded materials settle out in another place.
Deposition creates a delta.
WORTH 600 POINTS!!!
How are canyons formed? AND how are deltas formed?
Canyons are formed by erosion and deltas are formed by deposition.
A system of rivers, lakes, and streams that drain in an area is called a what?
drainage basin
