How Are Mountains Formed?
Mountains are formed over long periods of time by forces of the earth.
Mountains just don’t appear in any place. Most are formed when plates, or huge pieces of the Earth’s crust, pull and push against each other. Great mountain ranges are formed by the movement of tectonic plates. Convection currents deep in the mantle of the earth, begins to well up towards the surface. As the pressure increases, it sets the crustal plates in motion.
There are different kinds of mountains - Volcanic, Folded, Fault-block, and
Dome mountains. Volcanic mountains are formed when magma comes up through cracks in the Earth’s crust and explodes out lava and ash. The
Hawaiian volcanoes, Mt. Hood, Mt. Etna, Vesuvius, and Mt. Saint Helens are examples of volcanic mountains. Rocks are hard but in time they can bend or fold producing Folded mountains. The Alps formed as the Eurasian plate pushed against the African plate. Other examples of folded mountains are the
Rockies, Himalayas, Appalayas, and the Andes. Fault-block mountains are formed when one plate pushes or pulls away from another plate. In the Earth, hot currents of magma or molten rock may well up and crack the weakened crust above. As the crust cracks, blocks of rock rise or fall forming
Fault-block mountains. Examples of these mountains are the Sierra Nevada in
California and the Grand Tetons in Wyoming. Dome mountains are formed by the same kind of molten rock that forms Volcanic mountains. As magma comes up in a crack in the Earth’s crust, it does not come to the surface, but the molten rock pushes the ground up into a dome. Examples are Yosemite’s
Half Dome, the Adirondacks in New York, and the Black Hills in South
Dakota.Some mountains started at the bottom of the sea.

Later after the sea finally retreated occurred volcanic activity. Mountains rose through laccoliths, which also resemble volcanoes. These laccoliths differ in that they do not erupt. They shifted layers of rock upward in the shape of a dome. This specific piece of geologic morphology occurred at the end of the Cretaceous time. This marked the beginning of the Laramide Orogeny, which was a well-known period of mountain formation in western North America.
This interview should consist of open-ended questions to make Sara feel she is able to express herself in a manner she sees fit. To help a client, a clinician needs to be able to create rapport with a patient and creating an open conversation for Sara to express herself will help her let go of the refrigerator and have someone to confide in. As well this interview should include questions about how Sara feels about herself personally, how she feels about her body image, experiences or trauma she may have had pertaining to her body image and size, and her perceptions on the importance of being “skinny”. This interview will be the last factor determining whether Sara has Bulimia Nervosa. Bulimia Nervosa is linked to psychosis so more questions would need to be asked to see if Sara feels as if she is mentally flawed and she blames others for her flaws (Miotto et al., 2010). A test of Sara’s DNA would also be helpful in this case. Sara states that she was always large, in a taller sense, but given her obsession with bingeing and purging and possible weight size that has not been revealed, a simple thyroid test could determine whether issues with weight are possibly thyroidal and/or from bad lifestyle habits such as overeating. Current research has been done on the link between genetics and Bulimia Nervosa. Lewin and Carter (2014), state that neurotrophic factors are a group of proteins that supplement the growth and
Basalt forms due to the partial melting of the layer of the mantle called the asthenosphere. The asthenosphere is the plastic zone of the mantle beneath the rigid lithosphere. Mantle plumes coming from the mesosphere can cause the asthenosphere to melt with heat or even if pressure decreases, which is called decompression melting (Richard 2011). The magma that forms from this melting is mafic magma that solidifies once it reaches the earth’s surface and cools quickly. The above process mainly occurs mainly during intraplate igneous activity which is the main explanation for volcanic activity that occurs a long distance away from a plate boundary. If the tectonic plate above the mantle plume is moving it can create a string of volcanic activity such as in Hawaii. See Fig 2.
In any business money is the driving force, whether it is the owner or employee. Money is the greatest incentive for performance amongst employees Lincoln Electric defined this fundamental reason for driving employees to excel at their jobs. Aside from compensation there is an understating between mangers and their subordinates that both have the same fear toward lack of income, this commonality serves to encourage all employees to deliver quality and affordable products at the best market
When employees were asked, what factors could be changed at USAA to help maintain employee motivation levels, a couple of them answered with, “higher wages” and “more money”. This response corroborates other studies regarding pay which state surveys will more likely under emphasize the importance of pay relative to other motivational factors. (Rynes, Gerhart & Minette, 2004). “Financial incentives had by far the largest effect on productivity of all interventions. For example, pay was four times more effective than interventions designed to make work more interesting.” (Rynes, 2004). One reason for this phenomenon is social desirable responding. It should be noted, that although pay may be under reported, the results indicate other factors are also important for employee

Convection currents occur because the density of a fluid is related to its temperature. Hot rocks lower in the mantle are less dense than the cooler rocks above. The hot rocks rise and the cooler rocks sink because of gravity. Convection currents are thought to be the driving mechanism of plate movement. Convection currents cause convergent and divergent movements. When the rising part of the convection current rises it causes the upper mantle to move upward and in a lateral direction. This causes the mantle to split and new material to rise creating new ocean crust. The downward motion of the convection current pulls the mantle crust downward at convergent boundaries. When part of the mantle crust is uplifted the weight of the lifted part, pushes the sinking mantle down, causing motion in the tectonic plates.

In civilized societies, there are continuous prizing of thinness than ever before. Occasionally, almost everyone is watchful of their weight. Individuals with an eating disorder take extreme measures to concern where they ultimately shift their mode of eating, this abnormal eating pattern threatens their lives and their well-being. According to Reel (2013), eating disorders are continually misapprehended as all about food and eating. However, there is more to that as the dysfunction bears from emotion concealing a flawed relationship with food, physical exercise and oneself. Persons with eating disorders convey fault-finding, poor self- esteem and intense body discontent. This can lead to extreme distress of gaining weight,

If a ship happens to pass right over this large bubble in the water, the bubble bursts, and since methane gas causes water to lose its buoyancy, it sucks the ships right in the depths of the ocean. http://www.bermuda-attractions.com/bermuda2_0000a1.htm
Out of all mental illnesses found throughout the world, eating disorders have the highest mortality rate. Anorexia nervosa is one of the more common eating disorders found in society, along with bulimia nervosa. Despite having many definitions, anorexia nervosa is simply defined as the refusal to maintain a normal body weight (Michel, 2003). Anorexia nervosa is derived from two Latin words meaning “nervous inability to eat” (Frey, 2002). Although anorexics, those suffering from anorexia, have this “nervous inability to eat,” it does not mean that they do not have an appetite—anorexics literally starve themselves. They feel that they cannot trust or believe their perceptions of hunger and satiation (Abraham, 2008). Anorexics lose at least 15 percent of normal weight for height (Michel, 2003). This amount of weight loss is significant enough to cause malnutrition with impairment of normal bodily functions and rational thinking (Lucas, 2004). Anorexics have an unrealistic view of their bodies—they believe that they are overweight, even if the mirror and friends or family say otherwise. They often weigh themselves because they possess an irrational fear of gaining weight or becoming obese (Abraham, 2008). Many anorexics derive their own self-esteem and self-worth from body weight, size, and shape (“Body Image and Disordered Eating,” 2000). Obsession with becoming increasingly thinner and limiting food intake compromises the health of individuals suffering from anorexia. No matter the amount of weight they lose or how much their health is in jeopardy, anorexics will never be satisfied with their body and will continue to lose more weight.

The crust is the consequence of exploded mantle material originating from below the plate, cooled and in most cases, chemically changed by the seawater. These explosions occur typically at mid-ocean ridges.
A rift valley is formed on a divergent plate boundary. Divergence of plates happens because of slab pull (plates being pulled apart due to asthenospheric convection). When two plates are pulled apart, a ridge forms, and low-silica magma comes from inside the Earth to make a new crust (this is called plate formation). Rifts can occur at any location, of any elevation and on both types of plates. Rifts usually form vast valleys around the World (a commonly used example is the African Rift Valley, and it is still currently active). There are often large, incredibly deep lakes found in rift valleys (the deepest lake in the world, Lake Baikal is part of an active rift valley). Rift valleys have mostly shallow earthquakes, not devastating at all. Cracks in the valley with lava flowing out of them can also be found (volcanic fissures), along with cinder cone volcanoes. In Garibaldi Provincial Park, in British Columbia there is a cinder cone volcano, with cinder flats surrounding it, similar volcanoes can be found in rift
