What is the difference between the highest and lowest points of an area called?

• Elevation

• Relief

• Contour

• Delta

Which landform is made of sediment deposited where a river flows into an ocean or lake?

• Dune

• Delta

• Mountain

• Coastline

A group of parts that work together as a whole is called a:

• Model

• System

• Cycle

• Feedback

What is the process called in which map makers determine distances and elevations using instruments and geometry?

• Surveying

• Modeling

• Cycling

• Feedback

Which of the following best explains how feedback works in a system?

• It is a repeating flow of matter and energy.

• It is a loop where a signal or action triggers another signal or action.

• It is a group of parts working together.

• It is a line that forms a boundary.

Imagine you are a map maker. How would you use contour lines to help someone understand the elevation of a mountain?

• By drawing lines to show the boundary between land and water.

• By using lines to model the elevation, relief, and slope of the mountain.

• By piling sand to create a model of the mountain.

• By measuring the height above sea level only at the peak.

If a river flows into a lake and deposits sediment, what landform is most likely to form at the mouth of the river? Explain your reasoning.

• Dune, because wind piles up sand.

• Delta, because sediment is deposited where the river meets the lake.

• Mountain, because of high elevation.

• Coastline, because it forms a boundary.
