Question

interpreting maps • click new question: how do we interpret contour maps? 1. observe: look at the landscape and the corresponding topographic map. then use the add and subtract tools to create each of the following features: a hill, a depression, a ridge, and a valley. sketch the contour lines that represent each feature in the boxes below. (note: don’t forget to put hachure marks on the depression contour lines.) boxes labeled hill, depression, ridge, valley 2. calculate: the relief of a contour map is the difference between its highest and lowest points. what is the estimated relief of this map? handwritten 260m and a contour map image 3. practice: click new from the tools menu at lower left, select screen shot right - click the image and select copy image open a blank document and paste the screenshot. click new, and repeat this until you have at least 4...

Explanation:

For the "Calculate" part (estimating relief):

Step1: Identify highest and lowest points

From the map, highest point (hill) is 760 m, lowest (depression) is 500 m.

Step2: Calculate relief (difference)

Relief = Highest - Lowest = \( 760 - 500 = 260 \) m.

• Hill: Concentric closed contour lines, increasing in elevation towards the center.
• Depression: Concentric closed contour lines with hachure marks (short lines) pointing inward (lower elevation towards center).
• Ridge: Contour lines form "U" or "V" shapes opening downward (towards lower elevation), with the ridge line along the highest points of the "U"/"V".
• Valley: Contour lines form "U" or "V" shapes opening upward (towards higher elevation), with the valley floor along the lowest points of the "U"/"V".

Answer:

The estimated relief of the map is 260 meters.

For the "Observe" part (sketching contour features):
