Climbing the Tallest Mountains

Mountains are beautiful! Some people climb mountains. It is an adventure. It is a challenge!

The tallest mountains can be dangerous. The weather can be dangerous. It can be snowy. It can be icy. Snow, ice, and rocks can fall. The altitude is also dangerous. Altitude is how high something is above sea level.

At high altitudes, there is less oxygen. Oxygen is a gas in the air. Our bodies need oxygen to survive. When we do not have enough oxygen, we get sick.

When people climb tall mountains, they bring oxygen. They carry it in tanks. It helps them breathe. It helps them reach the top!
