Answer:
a. New Orleans, because pressure increases as you get deeper in the atmosphere and closer to the center of Earth
Explanation:
At sea level, the atmosphere pressures the earth's surface with approximately 1-kilogram per square centimeter strength. This means that at sea level, there is one ton of air making pressure over us. But this air pressure decreases with altitude.
At high level there is less air making pressure from above, and there is less gravity acting. Molecules are more separate from each other, and the density decreases.
