As you increase in altitude, there are fewer air molecules. Due to the lower amounts of air molecules, the atmospheric pressure decreases causing the air to be harder to breath in.

Answer:
Pictures from Hubble help scientists learn more about the whole universe.
Explanation:
Hubble has helped scientists learn about our solar system. The telescope observes comets and planets. Hubble even discovered moons around Pluto that had not been seen before. The telescope has helped scientists understand how planets and galaxies form. Galaxies contain billions of stars. A picture called "Hubble Ultra Deep Field" shows some of the farthest galaxies ever seen. Because of Hubble pictures, scientists think the universe is almost 14 billion years old.
