Ginny enjoys mountain climbing. Today she is climbing Mt. Sheridan, which is the tallest mountain she's ever climbed. When Ginny makes it to the top, she notices that it is more difficult to catch her breath. At higher elevations, why is it harder for Ginny to breathe?

• At higher altitudes, the air is too cold

• At higher altitudes, the air pressure is lower, fewer gas molecules are in the air

• At higher altitudes, the air contains too much nitrogen

• At higher altitudes, the air contains too much carbon dioxide
