The formation of solar systems

The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth’s gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation‚ warming the surface through heat retention (greenhouse effect)‚ and reducing temperature extremes between day and night (the diurnal temperature variation).The common name given to the atmospheric gases used in breathing and photosynthesis is air. Dry air contains roughly (by volume) 78.09% nitrogen‚ 20.95% oxygen

Formation of the Philippine Islands The Indo-Australian plate is found south of the Eurasian and the Philippine Seaplates. It is generally oceanic‚ being submerged by Indian and Pacific Oceans‚ but it holds two gigantic land masses – the island continent of Australia and Indian subcontinent. Recent researches‚ however‚ show that these two land masses are moving independently of each other‚ thus‚ may actually be parts of separate plates. The Philippine Sea plate is found east of the Eurasian

1. Summarize advances over time in determining the age of the Earth‚ including the importance of the discovery or radioactivity. Herodotus counted layers of earth near the Nile River in 450 B.C.E. The Bible was used in the Middle Ages to compute the age of the Earth. The 18th and 19th centuries brought a more scientific look into determining the age of the Earth by studying the salinities of the oceans‚ the rates of sedimentation‚ and models of cooling of different materials in order to calculate

Next to water and air‚ soil is most essential to our very existence on the earth. Soils are the basis of support for most life‚ and a source of nutrients for marine life and fresh water. As a natural resource‚ soil is of immense value to man. In the agricultural orient the distribution and density of population have conformed to the persisting patterns of soil fertility and productivity. Soil is basically broken-down rock materials and consists of decomposed rock debris and decayed organic

Origin of Earth and Evoluation of the Environment MODULE - 1 Environment through Ages 1 ORIGIN OF EARTH AND EVOLUTION OF THE ENVIRONMENT We live on a beautiful planet called earth‚ along with a wide variety of plants‚ animals and other organisms. Our earth‚ however‚ is part of a vast universe. The universe is about 15 to 20 billion years old. The age of the earth is approximately 4 to 5 billion years‚ while human beings evolved only around 2 million years ago. In this lesson‚ you shall learn

Material: Realms of the Earth Astro-physicists and scientists believe that there could be quite a few planets in the Universe similar to our planet Earth. There is also a probable chance that some form of life prevails and sustains in one of such planet. However‚ so far as we presently know‚ the Earth is the only planet which supports life which makes it a very unique planet. It is therefore imperative (very important and necessary) for us to understand the spheres of the Earth as the spheres play a

Formation of Volcanic Islands When people think of volcanoes‚ most would imagine a deadly explosion of liquid hot magma that ruthlessly obliterates anything in plain view. If volcanoes demolish everything in sight then how did life become what it is today? Volcanoes are not just a source of destruction and mayhem‚ long before civilization‚ while the earth was still being developed its apocalyptic surface consisted of nothing but molten rock and volcanic eruptions were a common occurrence; it was

Investigation 4- Formation of Deserts 1. There are high-pressure and low-pressure belts on Earth because of the differences in area that include the location‚ the mountain ranges‚ and the coastal areas. It also has to do with the uneven warming of the sun because of the rotation of the earth on its axis. It also has to do with the air that is found around the equator‚ as it is uneven. This causes for heat to raise which in turn causes low pressure. Then‚ the air that moves out of these “lows‚” toward
