Description
↓↓
A cave (doukutsu in Japanese) is a natural underground space, typically large enough for a person to enter. Caves are formed through various geological processes over thousands or millions of years, often by the erosion of rock through water, wind, or chemical activity. Caves can be found in a variety of environments, from coastal areas to mountains, and are significant both geologically and ecologically.
History
↓↓
Caves are natural underground spaces formed by geological processes such as erosion, volcanic activity, or dissolution of rock. Humans have used caves since prehistoric times for shelter, protection, and ritual purposes, as evidenced by Paleolithic cave paintings in Europe and other regions. Throughout history, caves have served as homes, religious sites, and storage areas. Today, caves are studied for archaeology, geology, and ecology, and are popular for exploration and tourism worldwide.
