ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans. The

depreciation and depletion play an integral part in a company ’s cash flow and profit or loss statements. Depreciation‚ according to investopedia is a method of allocating the cost of a tangible asset over its useful life. Depletion is very similar to depreciation with very subtle differences‚ the first one being what is depreciated verses depleted. All assets (except land) are depreciated but the assets with natural resources are depleted. The methods on how depreciation and depletion are calculated

California is in a drought and farmers believe our only option is to take water from under the ground. But‚ groundwater depletion is causing a lot of bad things to happen. It is making the layer of clay above collapse‚ when the clay collapses the dirt above gives way and sinks. This sinking causes sinkholes and is very dangerous. The sinking also damages pipes‚ buckles walls of irrigation canals‚ and cracks homes. Although the sinking is already a big enough threat the water in general could

Humans must take action to resolve them. This is because the world cannot exist without water. Every living thing depends on water and would not survive without it. Of all the water resource problems‚ one of the most important to solve would be the depletion of aquifer supplies. An aquifer is the body of sand that is able to store or produce large amounts of water. They can be anywhere from a few feet deep to a few hundred feet deep. From a bird’s eye view an aquifer can spread as far as a few hundred

Crust is the first and upper most layer of the Earth. There is Continental Crust which sits on top of Oceanic Crust. This layer is made frequently from granite rocks and is solid. Continental Crust is approximately 32km. Below the Continental Crust is Oceanic Crust. It is about 8km. This part of the Crust is made from basalt rocks. The Crust is most of lithosphere and is the coolest layer by far. Mantle is like silly putty consistency. It is the largest layer of Earth sitting under the Crust.

There are many different layers within the Earth. The core is at center of the Earth. The Earth’s core takes up sixteen percent of Earth’s volume‚ containing thirty-three percent of its Mass ..Pressure rises steadily inside the earth because of the weight of overlying rock. Therefore ‚the Pressure at the outer boundary of the core reaches 1.37 million atmospheres‚ 3.7 million Atmospheres. The core is made mostly of iron and nickel and possibly smaller amounts of lighter elements including sulfur

of depleted self control resources is known as ‘ego depletion’ and the purpose of this study was to see how our capacity to inhibit urges can be affected by ego depletion. This study was also done to test the effects of beliefs about self control on subsequent performance in self control tasks. Participants’ performance on the Stroop task and phonemic fluency task and subjective feelings of tiredness were assessed before and after an ego depletion task‚ one group was primed to believe that self control

BOUNDARY LAYER THEORY INTRODUCTION The concept of boundary layer was 1st introduced by L.Prandtl in 1904. Figure 7-1. Viscous flow around airfoil A structure having a shape that provides lift‚ propulsion‚ stability‚ or directional control in a flying object. Boundary layer is formed whenever there is a relative motion between the boundary and the fluid. Boundary layer thickness: 1.

1. Crust: The Earth’s surface is composed mostly of water‚ basalt and granite. Oceans cover about 70% of Earth’s surface. The Earth’s thin‚ rocky crust is composed of silicon‚ aluminum‚ calcium‚ sodium and potassium. The crust is divided into continental plates which drift slowly (only a few centimeters each year) atop the less rigid mantle. The crust is thinner under the oceans; this is where new crust is formed. Continental crust is about 25-90 km thick. 2. Mantle: Under the crust is the rocky
