Put a box around land being created.

Put an arrow where the newest land
is located
Convection: The process by which heated, less material rises and cooler, more dense material sinks.

(Review from 6th grade)
Define Weathering: When wind, water, etc break larger rocks into smaller rocks and sediment.______________
Define Erosion: When wind water, etc move rocks, soil and sediments______________
Define Deposition: When rocks, soil or sediments are dropped in a new place.__________
11. What is the contour interval? ______30m__
12. About how high above sea level is Mountain A?
________270m_______
13. About how high is Mountain B? ____300m_____
14. Which mountain has the highest elevation? _____B_____
15. Is the east slope or west slope of Mountain B steeper?
________East___________
16. In which direction does the river flow? ____West_____
17. Predict how the land would change if the flow of water in
the river continued to increase. _________________________
The contour lines would be further apart as the slope became
more gentle due to erosion.
