Understanding Depth and Elevation Concepts

This video tutorial covers lesson seven on sea level, focusing on understanding elevations and depths using integers. It provides directions for labeling the elevation or depth of objects in a diagram and includes examples of calculating how much higher one object is compared to another. The tutorial explains the concept of sea level, elevation, and depth, and demonstrates calculations using integers, such as finding the difference between the elevation of a palm tree and the depth of a fish. It concludes with a calculation of the height of a sailboat from the top of the mast to the bottom of the keel.

What is the task given in the lesson regarding the diagram?

• Draw new objects in the diagram.

• Label the objects using colors.

• Calculate the weight of each object.

• Label the elevation or depth of each object using integers.

What is the elevation of the beach ball in the diagram?

• 3 feet above sea level

• 4 feet below sea level

• 8 feet above sea level

• 0 feet, at sea level

How is the depth of the fish represented in the diagram?

• 8 feet below sea level

• Negative 4 feet

• 0 feet, at sea level

• 4 feet above sea level

What is the elevation of the palm tree?

• 0 feet, at sea level

• 4 feet below sea level

• 8 feet above sea level

• 3 feet above sea level

What is the significance of using negative numbers in the context of this lesson?

• To represent objects above sea level

• To represent objects below sea level

• To represent objects at sea level
