Ice volcanoes form during winter months and are found on the lakes. Ice volcano is commonly observed in the Lake Superior during winter months. Ice shelf starts building into the lake with cones formation at the leading edge in the lake. Strong winds hitting onshore drive the waves that hits the bottom to develop and break on the ice shelf. As the ice shelf reaches its maximum build waves travel beneath the ice and move with force through the preformed cones and cracks.
Ice volcanoes need certain conditions to be satisfied before they are formed. High tidal waves presence is required in the area. Intensity of the eruption is determined by the height of the wave and the direction of the wave. Cones are difficult to form if the amplitude of the waves is less than one meter. Heavy onshore winds triggered by storms and squalls with required wave height [...] Continue Reading…
In a wood fire, the wood is heated by lightning, burning match stick, friction or a focused point of sunlight. Decomposition of a portion of the cellulose material happens when the wood reaches about 260 deg Celsius.
Decomposed material degenerates to volatile gases that are commonly termed smoke. Smoke is composed of hydrogen, carbon and oxygen. At this stage, the compound molecules disintegrate and the atoms undergo recombination to form water, carbon dioxide and other gases. This process is called burning. Burning emits light. Flame is a product of light through heat and the effect is called incandescence. Colors of the flame depend on the material being used for burning and the temperature. Hottest part or the base of the flame is blue and the top of the flame is orange or yellow in color.
How a flame burns is determined by the Earth’s gravitational force. Fire is a chemical reaction [...] Continue Reading…
Yellowstone national park is situated mostly in the State of Wyoming in the United States of America. Almost half of the geothermal features and world’s two-thirds of geysers are concentrated in Yellowstone. The largest hot spring in the park, and one of the largest in the world, is Grand Prismatic Spring. Steamboat Geyser located in Yellowstone’s Norris Geyser Basin with its eruptions as high as 380 feet (116 meters) is the world’s highest geyser. In 2002, Steamboat erupted twice (April 26 and September 13); in 2003, three times (March 26, April 27, and October 22); and most recently in 2005, on May 23.
Hot spring is a vent or a place in the ground where hot ground water comes out on regular intervals for a predictable time period of a year with the temperature of the water significantly higher than the ground temperature.
Hot springs are formed if the [...] Continue Reading…
