Darlene Garcia GEO 151 Prof. Denyse Lemaire WA1 Feb. 2010 1. What are the relationships among Earth’s mantle‚ crust‚ asthenosphere‚ and lithosphere? The core is divided into three major compositional layers. The crust on Earth’s surface‚ the rocky mantle beneath the crust and the metallic core which is the center of the Earth. While distinct and separate parts of Earth‚ they are all interconnected. The metallic inner core is solid‚ surrounded by a liquid (molten) outer core. Most of

Heat Stress in the Work Place! Eastern Kentucky University Heat Stress is the exposure to extreme heat or working in hot environments. Workers who are exposed to this may be at risk of heat stress. Heat Stress can result in occupational illnesses and injuries. “Heat stress can result in heat stroke‚ heat exhaustion‚ heat cramps‚ or heat rashes. Heat can also increase the risk of injuries in workers as it may result in sweaty palms‚ fogged-up safety glasses‚ and dizziness. Burns may

about different ways to help with weight loss. Weight can be a harmful factor in an individual’s life‚ it is not only about the body mass but weight often plays a role mentally and physically if it is abused. For example‚ being overweight can lead to obesity and low self-esteem. Losing weight can be a challenge‚ so many people look for the most effective way to lose weight through surgical procedures and weight lost programs. There are a variety of weight loss programs that offer extended support and

encompasses the degree of variations in organisms and/ or species within an ecosystem. The loss of biodeversity would be the diminishing of dfferent species within that ecosystem. For example‚ a lake may be the home to many types of fish. A change in the lake’s temperature or chemistry may affect a food source for a certain type of fish. This type of fish may die out and leave the lake with one less species in it. The loss of one fish or food source may impact other populations and furthe diminish species

Title: Specific Heat of Solids II. Object: To determine the specific heat capacity of solids by methods of mixtures. III. Theory: When to or more substances at different temperatures are mixed‚ heat will flow from the substance of higher temperature to the substance of lower temperature. The heat flow will continue until equilibrium in temperature is reached. From the Law of Conservation of Energy‚ whatever amount of heat is lost by the hot substance must be equal to the heat gained by the cold

project is on the surface tension of water and what affects the surface tension of water. The question that I am going to ask is how does temperature and salinity of water affect the surface tension of the water. My hypothesis is that the colder and the saltier that the water is‚ the stronger that the surface tension of the water will be. Some of the background research that I have done has explained to me that the surface tension of water is a property of a liquids surface that can cause it to

Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above
