Research question:
Which type of glacier deposits more sediment per square meter, continental glaciers or valley
glaciers?
Hypothesis:
I think that continental glaciers deposit more sediment than valley glaciers; i think this because
continental glaciers are bigger and heavier than valley glaciers so they do the process of plucking
more than valley glaciers. So, if there is more erosion there is more deposition.
Materials:
A continental glacier
A valley glacier
An airplane
Dump trucks (number of trucks depend on the amount of sediment in glaciers)
Meter tape
People (number of people depend on the amount of sediment)
Lab room
Procedure:
1. a lot of people (for example 25) go on an airplane to a continental glacier (for example
Greenland)
2. In there they will go to places where there is deposit sediment, with the meter tape,
measure the area with sediment.
3. There, they will put the sediment in the dump trucks
4. Then they will take the trucks with sediment to the lab room.
5. There they will measure the number of sediment with the meter tape by measuring
the volume of the truck and then measuring how much volume of the truck does the
sediment occupies.
6. Then in the airplane the people will go to a glacier valley, there they will do steps 2-5.
7. then in the lab room calculate results and compare results.
