DO U LIKE WATER FALLS?

I think waterfalls are awesome. I even enjoy walking back in someplace to see just a little one. I've been to Niagara Falls several times, and those are terrifyingly amazing. I can't imagine anyone ever trying to go over those falls. I have a picture in my picture gallery that someone sent me of Niagara Falls when it froze solid in 1911 if you'd be interested in looking at it.

Absolutly. Waterfalls are so peacefull. The sound of the water rushing rapidly over the rocks could lull me to sleep. I also love the spray, being gently misted by it on a hot day is like heaven on earth.

A waterfall is usually a geological formation resulting from water, often in the form of a stream, flowing over an erosion-resistant rock formation that forms a sudden break in elevation. Waterfalls may also be artificial, and they are sometimes created as garden and landscape ornament. Some waterfalls form in mountain environments where erosion is rapid and stream courses may be subject to sudden and catastrophic change. In such cases, the waterfall may not be the end product of many years of water action over a region, but rather the result of relatively sudden geological processes such as landslides, faults or volcanic action.Typically, a stream flow across an area of formations strata will form shelves across the streamway, elevated above the further stream bed when the less erosion-resistant rock around it disappears. Over a period of years, the edges of this shelf will gradually break away and the waterfall will steadily retreat upstream, creating a gorge of recession. Often, the rock stratum just below the more resistant shelf will be of a softer type, meaning undercutting, due to splashback, will occur here to form a shallow cave-like formation known as a rock shelter (also known as a rock house) under and behind the waterfall. Eventually, the outcropping, more resistant cap rock will collapse under pressure to add blocks of rock to the base of the waterfall. These blocks of rock are then broken down into smaller boulders by attrition as they collide with each other, and they also erode the base of the waterfall by abrasion, creating a deep plunge pool. Waterfalls can also form due to glaciation, whereby a stream or river flowing into a glacier continues to flow into a valley after the glacier has receded or melted. The large waterfalls in Yosemite Valley are examples of this phenomenon. Streams become wider and more shallow just above waterfalls due to flowing over the rock shelf, and there is usually a deep pool just below the waterfall due to the kinetic energy of the water hitting the bottom. * Block: Water descends from a relatively wide stream or river. * Cascade: Water descends a series of rock steps. * Cataract: A large waterfall. * Fan: Water spreads horizontally as it descends while remaining in contact with bedrock. * Horsetail: Descending water maintains some contact with bedrock. * Plunge: Water descends vertically, losing contact with the bedrock surface. * Punchbowl: Water descends in a constricted form, then spreads out in a wider pool. * Segmented: Distinctly separate flows of water form as it descends. * Tiered: Water drops in a series of distinct steps or falls. * Multi-Step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool.
