Four landmarks in the United States and their elevations are listed
below.
• Death Valley at 279 feet below sea level
• New Orleans at 8 feet below sea level
• Salton Sea at 226 feet below sea level
• Lake Michigan at 579 feet above sea level
Order the landmarks from the lowest point to the highest point.

Ordering from lowest point to highest point, we have;

Death valley

Salton sea

New Orleans

Lake Michigan

Step-by-step explanation:

In this question, we are concerned with arranging the landmarks in the question in ascending order.

The important properties needed to be understood here are the definitions of above sea level and below sea level

Let's consider the sea level as a flat bed. When we say above sea level, we mean the structure has its base on the sea level and projects upwards. When we say below see level, it means that particular structure has gone farther and deeper into the sea at depths which are deeper than the sea level itself.

Lake Michigan is the the highest point as it is the only above sea level landmark that we have in the question.

We have three landmarks left. Their respective position relative to the sea level can be rephrased to mean at a depth of.

Now looking at the three, Death valley is the deepest here, followed by Salton sea and finally New Orleans
