Understanding Elevation and Sea Level

The video tutorial explores the concept of elevation using real-world examples, focusing on representing elevations as integers. It includes exercises on graphing these integers on a number line and correcting statements about elevations. The tutorial emphasizes understanding the zero point and avoiding redundancy in integer representation.

What does the term 'elevation' refer to in the context of this lesson?

• The height above or below sea level

• The height of a person

• The depth of the ocean

• The distance from the ground to the sky

How would you represent the elevation of a diver who is 30 feet below sea level as an integer?

• 30 feet

• 0

• -30

• 30

If a hiker is 10,560 feet above sea level, what integer represents this elevation?

• -10,560

• 0

• 10,560

• 1,056

What is the integer representation of a sailor at sea level?

• -1

• 0

• 1

• 100

When graphing elevations on a number line, what is an appropriate scale if you have values like 15 and -20?

• By fives

• By tens

• By twos

• By ones

How would you correct the statement: 'The depth of the submarine is negative 800 feet below sea level'?

• The depth of the submarine is negative 800 feet

• The depth of the submarine is 800 feet above sea level

• The depth of the submarine is 800 feet below sea level

• The depth of the submarine is negative 800 feet above sea level

What is the correct way to express the elevation of a coral reef that is 250 feet below sea level?

• 250 feet above sea level

• Negative 250 feet above sea level

• Negative 250 feet below sea level

• 250 feet below sea level

Why is it important to avoid redundancy when representing integers in elevation?

• To make it sound more scientific

• To use more words

• To avoid confusion

• To make it sound more complex

What is the significance of zero in the context of sea level?

• It is the lowest point

• It is the dividing line between positive and negative elevations

• It is not significant

• It represents the highest point

What should you remember when completing the problem set related to elevations?

• To always use positive numbers

• To ignore the sea level

• To understand where zero is and avoid redundancy

• To use complex numbers
