what r natural geysers?

This will explain what they are and how they occur. I have been to Yellowstone National Park and I have seen them.  They are very impressive to watch.\n\nwww.uweb.ucsb.edu\n\nWhat are geysers and why are they so rare?\nA geyser is a hot spring that periodically erupts, throwing water into the air. Though that sounds simple, geysers are extremely rare. As of December 2005, the total of active geysers on earth number approximately 1000. \n\n Conditions must be just right for geysers to occur. Three components must be present for geysers to exist: an abundant supply of water, an intense source of heat, and unique plumbing. Water is common in nature, heat can come from volcanic activity, but the plumbing is critical. For water to be thrown into the air, geyser plumbing must be water- and pressure-tight. Geyser scientists and observers have identified the volcanic rock rhyolite as being particularly effective at hosting geysers. Rhyolite is high in silica, which can deposit a water-tight seal along the walls of the geyser plumbing. Most of the geyser fields in the world are found in rhyolite or similar silica-laden rocks (like ignimbrite). The mixture of water, volcanic heat, and plumbing is exceptional at Yellowstone National Park. Over one-half of the world's geysers are located within the park's boundaries.\n\nIt is increasingly apparent that geysers must possess a fourth characteristic to exist: remoteness. Within the last fifty years, volcanic heat and abundant water have been increasingly harnessed to turn turbines for electricity production. Geothermal energy can be produced at any site where volcanic heat and water are readily available. Unfortunately, geyser fields are ideal for this type of energy production. Geothermal energy production steals the geysers' water, and destroys geyser activity (for example, Wairakei, New Zealand). A growing threat to geysers stems from mineral extraction. Hot groundwater may precipitate gold or other valuable minerals, and extraction may require removing the geyser plumbing itself. For example, in May 2003, mineral exploration at South America’s second largest geyser field (Puchuldiza, Chile), caused cessation in the field’s geysers. Few realize the actual rarity of geysers. As a result, many geyser fields have been destroyed and many others are being threatened. \n\n\nHow do geysers work?\n\nThe following is an excerpt from Scott Bryan's GEYSERS OF YELLOWSTONE, 3rd edition, copyright 2001. It is reproduced here for educational purposes. Scott Bryan's book not only describes each Yellowstone geyser in detail, but also includes descriptions of geyser fields worldwide. It is probably the best book on geysers out there. Buy it or check it out!\n\n\nThe hot water, circulating up from great depth, flows into the plumbing system of a geyser. Because this water is many degrees above the boiling point, some of it turns to steam instead of forming liquid pools. Meanwhile, additional, cooler water is flowing into the geyser from the porous rocks nearer the surface. The two waters mix as the plumbing system fills.\n The steam bubbles formed at depth rise and meet the cooler water. At first, they condense there, but as they do they gradually heat the water. Eventually, these steam bubbles rising from deep within the plumbing system manage to heat the surface water until it also reaches the boiling point. Now the geyser begins to function like a pressure cooker. The water within the plumbing system is hotter than boiling, but "stable" because of the pressure exerted by all the water lying above it. (Remember that the boiling point of a liquid is dependent upon the pressure. The boiling point of pure water 212 degrees Farenheit (100 degrees Celsius) at sea level. In Yellowstone the elevation is about 7,500 feet, the pressure is lower, and the boiling point of water is only about 199 degrees Farenheit (93 degrees Celsius).\n\nThe filling and heating process continues unt

Hot springs occur near areas where magma (the stuff that makes volcanos erupt) is close to the surface. These are usually areas near volcanic regions.  Water from springs runs over the magma. It gets heated as it rises to the surface. They are more of a natural hot tub than anything else. People attribute medicinal properties to them. The water often has dissolved minerals in it. Some people drink it.

Water is a natural by-product of combustion within jet engines.  This moisture condenses and freezes at the cold temp found at high altitudes.  This is called a "Con trail" which is short for condensation trail.

It is very hard to understand what you are asking. Since groundwater is beneath the surface of the earth, it would generally not be considered to have 'landforms'. However, if there are any landforms in the water table they are what are called phreatic caves. These are caves that exist below the water table. Another sort of 'landform' that might exist within groundwater, or beneath the water table are the buried sedimentary features that exist within most sedimentary rocks. Examples of these would be sand bars, deltas, river channels, natural levees, carbonate platforms, incised valleys, alluvial fans, and just about any geomorphic feature that exists on the surface. \n\nAnother way to understand your question would be that perhaps you are asking about how surface landforms affect groundwater. The water table is often elevated under higher topographic features such as hills. Often there is a hydrostatic gradient where water is slowly moving through saturated aquifers downward toward valleys. This type of flow can even create artesian springs.

I just recently watched a program on the Discovery channel and has been researched as a site of the world's largest mega volcano's... and has been deemed to be getting ready for another huge explosion which could change the whole planet as we see it. Although it does look interesting to look at Old Faithful the famous geyser, it is also one of the most dangerous sites and I wouldn't want to be near it when it does erupts.

Old Faithful Geyser is Yellowstone National Park, in Wyoming. I have provided you with a link to the Old Faithful Webcam.  Look at it for actual real time pictures. (during the day_

By erosion and quakes and volcanic activity and plate tectonics. that is the natural thing that change it. The unnatural things are construction like the Piramids and the California Aquaduct and power plants and buildings. And the distruction of the rain forests and exploration of the ocians. And so much more. The surface is in constant flux and always changing.

Simple answer?\n\nC - Groundwater\n\nWater and air fill the spaces down to the zone of saturation, i.e. the water table, though its not really a flat surface in the ground. As one goes deeper, saltwater encroaches becoming brines.\n\nIn some areas where the geology is right and structural traps exist in the formations, oil and natural gas can occupy fractures and pore spaces.

to change nature will take a very long process...\nbut to stay natural is , drink a lot of fluid, avoid direct sunlight and make sure drink a lot of water...
