Caves

Caves are special spaces under the ground where you can explore. They are found all around the Earth and even on other planets like Mars! These amazing places form mostly through the weathering of rock over many years.

People love to visit caves because they are fun and exciting. When people go inside caves, it is called caving, potholing, or spelunking. Exploring caves helps us learn about the history of our planet and the special life that lives inside them.

Caves can form in many ways. Most caves form in limestone through a process called dissolution. This happens when rainwater, which has a tiny bit of acid, flows over the limestone and slowly makes space for a cave. Inside these caves, you can see beautiful shapes like stalactites and stalagmites, which are made of calcium carbonate.

There are also caves made by volcanic activity, called lava tubes. These form when hot lava flows downhill, and the outside cools and hardens, leaving a tunnel behind.

Some caves are found along the coast and are called sea caves. Waves of the ocean shape these caves over time. They can be very long and sometimes even reach above the water.

Caves are special because they are homes to unique animals. Some animals, called troglobites, can only live in caves. They often look different from other animals because they don’t need eyes or colorful skins. Instead, they have very good senses to feel vibrations.

People have used caves for thousands of years. Some of the oldest paintings in the world are found in caves, showing that early humans liked to create art in these hidden spaces. Caves can also have special sounds, which people have used for music for a very long time.
