PART A Using the graph to the right, what would Air Pressure be (mb) at an altitude of 10 km? What is the approximate altitude where the air pressure is 400 mb?

PART B At an altitude of 0 km, what is the air pressure in mb?

The image is a graph displaying the relationship between atmospheric pressure and altitude within Earth's atmosphere. The graph measures pressure in both millibars (mb) and inches, and altitude in both kilometers (km) and miles.

### Graph Explanation:

- **Axes:**
- The x-axis represents atmospheric pressure, ranging from 0 to 1,200 mb and 0 to 35.5 inches.
- The y-axis represents altitude, ranging from 0 to 100 km and 0 to 62 miles.

- **Pressure-Altitude Curve:**
- A red curve shows how atmospheric pressure decreases as altitude increases.

- **Atmospheric Layers:**
- **Troposphere**: The lowest layer, extending from the surface to about 10 km (6 miles). The pressure at the surface is marked at 1013.2 mb.
- **Stratosphere**: Above the troposphere, it extends from approximately 10 km to 50 km (6 to 31 miles).
- **Mesosphere**: Extending from the stratosphere to about 80 km (50 miles).
- **Thermosphere**: The uppermost layer shown, continuing from the mesosphere to 100 km (62 miles).

This graph visually represents how atmospheric pressure rapidly decreases with an increase in altitude, and it provides a clear demarcation of the different layers of the Earth's atmosphere.

Expert Solution

Step 1: Determine the air pressure at an altitude of 10 km and 0 km and altitude, if air pressure 400 mb.

Given:

The graph of altitude Vs pressure.

The $x$ axis of the graph is pressure and $y$ axis of the graph is altitude.

Concept used:

Observe the graph and find the intersection of the graph of alltitude and pressure to the curve to obtain the air pressure or alltitude.
