Carbon Dioxide Emissions at Mammoth Mountain, California :: Nature Volcano Essays

Carbon Dioxide Emissions at Mammoth Mountain, California According to Dr. David P. Hill and Dr. Roy R. Bailey of the United States Geological Survey, the most common geological question in Mammoth, California is Where is the volcano? Although Mammoth Mountain does not resemble the classically recognized cone-shaped volcano, the mountain experienced significant volcanic and seismic activity in the past two decades, which have brought the mountain the recognition as a potentially hazardous volcano. A massive volcanic explosion 760,000 years ago created the Long Valley Caldera in California. A build up of magma beneath the earth's surface caused an uplift of the crust which led to the explosion. Afterwards, the crust sank over a mile, into a depression measuring 10 miles wide and 20 miles long. A magma chamber still exists beneath the caldera. The fumaroles and hot springs confirm the presence of a magma body. The underground magma heats groundwater which rises to the surface and releases in hot springs or steam vents (Hill et al. 2000). Recent uplifting caused the Resurgent Dome in the middle of the caldera to rise 2.5 feet over the past two decades. This volcanic unrest, on a previous stable volcanic system, prompted the USGS to put in place an Emergency Response plan and to closely monitor the region for further signs of unrest (Hill et al. 2000). The Mono-Inyo Crater volcanic chain lines the southwest side of the Long Valley Caldera. Mammoth Mountain, a volcano within the Mono-Inyo chain, formed 50,000 years ago from multiple dacite eruptions (Sorey et al. 1999) Dacite magma is an intermediate between rhyolite and andesite (Kearey 2001). Over the last 5,000 years, eruptions in the Mono-Inyo volcanic chain occurred periodically every 250-700 years. The active volcanic chain is being closely monitored for signs of future eruptions which include earthquakes, uplift of magma and gas emissions (Hill et al. 1998). Starting in the 1980's numerous earthquake swarms took place throughout the Long Valley Caldera concentrated in the southern section of the caldera. In May of 1989, seismic activity started in Mammoth Mountain, a volcano on the southwest edge of the Long Valley Caldera, with a period of earthquake swarms. Scientists collected data indicating that a dike was rising beneath the mountain and intruded 2 km below the surface of Mammoth Mountain (Sorey et al.

Importance of Child Friendly Education Essay

All this does not mean that you turn your class into a place of dreary learning. First of all, the activities you would use with adults can work, but make them shorter. For example, a role play may have to last five minutes instead of 10. Also make sure activities are varied: an activity that involves moving about and noise needs to be followed by a quiet task that allows kids to â€Å"cool down†. Remember also that children will not do a task because it is good for their English. Tasks need an end result rather than being open-ended. Building in a quiz or competitive element can work or ask learners to produce work that is displayed on the wall. It’s a great feeling when the children are busy, but their enjoyment of a task might manifest itself in terms of noise. Develop signals to get attention. This can be a raised hand or switching off the lights. Whatever you do, don’t try to out-shout a class because they will always win. Where groups of children are getting really loud it may be time to change the groups around. Adults like praise, but children really love praise. Avoid over-praising individuals and try to compliment whole groups. Use affirmative commands like, â€Å"Please speak English† rather than negative reprimands like, â€Å"Stop speaking Spanish!† You’ll also avoid problems if you set out rules at the beginning of the course. If possible, involve the children in preparing and writing out the class rules – it is especially good practice with modal verbs. A child that then breaks these rules will see greater justice than if you make up your own rules on the spot. More importantly, you will be punishing the inappropriate behaviour, not the child.
