Understanding Elevation and Depth

The video tutorial explains how to measure the height of a mountain using elevation, which involves understanding positive and negative numbers in relation to sea level. It covers the concept of elevation as height, the use of vertical number lines, and the significance of sea level as zero elevation. Examples include mountains, fish, planes, and submarines to illustrate positive and negative elevations. The tutorial concludes with a volcano example, reinforcing the relationship between elevation and sea level.

What does elevation refer to in the context of measuring a mountain's height?

• The distance from the base to the peak

• The width of the mountain

• The depth of the mountain's base

• The height above or below sea level

Which of the following statements is true about sea level?

• Sea level is considered zero elevation

• Sea level is the average height of mountains

What does a positive elevation indicate?

• The location is at sea level

• The location is below sea level

• The location is underwater

• The location is above sea level

If a fish is swimming 65 ft below sea level, what is its elevation?

• 65 ft above sea level

• 150 ft above sea level

• 65 ft below sea level

• 0 ft

Which of the following is an example of a location with negative elevation?

• A plane flying at 10,000 ft

• A fish swimming below the ocean surface

• A valley above sea level

• A mountain peak

What is the term used to describe the height at which planes typically fly?

• Latitude

What is the relationship between positive and negative numbers and elevation?

• There is no relationship

• Positive numbers indicate below sea level

• Negative numbers indicate above sea level

• Positive numbers indicate above sea level, and negative numbers indicate below sea level
