Mantle 825 miles
Crust 63 miles
The moon has three layers: the core, the mantle, and the crust. Each of the depths are shown in the table. In 3–5 sentences, explain what the total distance is from the core to the crust represented on a horizontal number line. What is the total distance from the mantle to the crust on a horizontal number line?

Answer 1

To find the total distance from the core to the crust on a horizontal number line, you would add the depths of each layer together: 149 miles (core) + 825 miles (mantle) + 63 miles (crust) = 1037 miles. So, on a number line, the total distance from the core to the crust would be 1037 units.

To find the total distance from the mantle to the crust on a horizontal number line, you would add the depths of the mantle and crust together: 825 miles (mantle) + 63 miles (crust) = 888 miles. So, on a number line, the total distance from the mantle to the crust would be 888 units.
