Atmosphere. Essay

1505 words - 6 pages

Our air holds a mixture of many gases, liquid droplets and solid particles, but 99% of our air is made up of nitrogen and oxygen. The life process of all plants and animals depend on nitrogen and carbon dioxide. Plants produce oxygen by photosynthesis. The key to photosynthesis is the ability of chlorophyll, the green pigment in plants, to convert sunlight into chemical energy.In measuring the temperature of the atmosphere we find that there are four levels where the temperature varies greatly. These levels are troposphere, which because of gravity is held closest to the surface of the earth and rises to about ten miles. The atmospheric conditions of the lower troposphere are referred to collectively as weather. As you near the top of the troposphere the temperature decreases to as much as -60 degrees F.The stratosphere covers about the next forty miles and as you go higher into the stratosphere the temperature again rises. Above the stratosphere, from about thirty miles to fifty miles is the mesosphere here the temperature again falls, dropping to as little as -140 degrees F.Above the mesosphere the temperature of the thermosphere varies considerably with solar activity. The thin atmosphere is heated intensely by the suns rays and can reach temperatures to over 1800 degrees F. Ozonosphere and Ionosphere are also divisions in the atmosphere.Within the ozonosphere lies the ozone layer. Ozone is formed by the dissociation of molecular oxygen and the combining of atomic oxygen with molecular oxygen. This is accomplished with the appropriate ultraviolet (UV) radiation and oxygen at an optimum altitude of about twenty miles.The ionosphere is made up of electrically charged ions and electrons that are trapped in the earth's magnetic field. These form ionic layers in the upper region of the atmosphere. The ionosphere provides global radio communication via the reflection of waves from the ionic layers. The ions and electrons that are trapped, coupled with solar disturbances combine at the earth's poles to create the northern lights (aurora borealis) or southern lights (aurora australis).The sun is the most important source of energy on the earth's surface. Its energy spreads through space in the form of radiation and because of the tilt on the earth's axis we only catch a small portion of this radiation. But the earth's rotation around the sun is what causes our season. Incoming solar radiation or insulation fluctuates, but is fairly constant and the earth gets an average of 50% or less at the surface depending on atmospheric conditions.One third of the insulation is returned to space as a result of reflection from the clouds, scattering of particles in the atmosphere and reflection from ground surface such as water and ice. This is known as albedo.The color of our sky is caused by the scattering of molecular particles affected by wavelengths of incident light. The troposphere derives most of its energy from the earth. It absorbs it in the form of...

Volcanic Eruptions and the Atmosphere

1314 words - 6 pages In what ways do the volcanic gases from volcanic eruptions develop the atmosphere? When a volcano erupts, a plethora of debris and other hazards flows out from the mouth of the volcano. Of this debris, one of the most perilous threats is not only the lava but also any gases that are a product of the eruption. In fact, these gases that are released during, after, and sometimes before an eruption are one of the main culprits as to why volcanos

Amazing Atmosphere of the Earth

603 words - 2 pages The Earth’s atmosphere is divided up into the Troposphere, Stratosphere, Mesosphere and the Thermosphere. The Earth’s ozone layer is located in the lower stratosphere, which begins about 6 to 10 miles above the Earth’s surface and expands up to about 30 miles. The ozone layer shields all life on earth and protects it from the dangerous radiation of the sun. UV Radiation The ozone layer acts as a safeguard against the harmful radiation of the sun

The structure and composition of the atmosphere

528 words - 2 pages The Earth is surrounded by a blanket of air, which we call the atmosphere. It reaches over 560 kilometers (348 miles) from the surface of the Earth, so we are only able to see what occurs fairly close to the ground. Life on Earth is supported by the atmosphere, solar energy, and our planet's magnetic fields. The atmosphere absorbs the energy from the Sun, recycles water and other chemicals, and works with the electrical and magnetic forces to
