Waterfalls can be formed in several ways, but the most familiar method of building is that a river courses over a top layer of resistant bedrock before slipping onto the softer rock, which erodes faster, leading to an increasingly high fall. Waterfall has been studied for their influence on species living in and around them.
Humans have had a distinct association with waterfalls for years, touring to see them, exploring and naming them. They can present challenging barriers to navigation along rivers.
These are sacred sites in many cultures. Activities at a waterfall can contain bathing, swimming, photography, rafting, canyoning, abseiling, rock climbing, and ice climbing. The waterfall can also be a place for forging hydroelectric power and can hold good fishing opportunities.
Waterfall plays a part in many cultures, such as holy sites and subjects of art and music. Many artists have painted waterfalls.
