The earth is a huge sphere. The surface of which is made up of rock, soil and water. It is surrounded by air. The planet earth is only a tiny part of the universe, but it is the home of human beings and many other living things. Animals and plants live almost everywhere on the h..

The depletion of ozone layer poses a severe threat to mankind. Along with the above-mentioned gases, other pollutants such as methane (CH 4 ), carbon dioxide (CO 2 ) have caused a hole in the ozone layer. A hole or a decreased concentration of ozone in stratosphere results in t..

Example 19: The ozone in the ozone layer protects the earth from harmful ultraviolet radiation by trapping these radiations. This ozone layer has been thinning gradually and poses potential health hazards for the future. The thinning of ozone layer has been ..

In outward appearance, the earth is a nearly spherical ball with a radius of 6350 kilometers. Internally, the earth consists of three major layers..

During the formation of the Earth, cooling of gaseous mixtures took place and molten earth condensed to form different earth zones or layers. Each layer that formed on top of the other had a definite chemical composition and thus a distinct distrib..

In outward appearance, the earth is a nearly spherical ball with a radius of 6350 kilometers. Internally, the earth consists of three major layers. They are: Crust Mantle Co..

. The earth's earliest atmosphere may have contained hydrogen, helium, methane and ammonia, similar to the present atmosphere of Jupiter. Or it may have contained a large amount of carbon dioxide, as does the atmosphere of Venus. The earth's earliest atmosphere probably did not ..

Most elements are formed due to fusion of simple nuclei to give heavier nuclei i.e., nucleosynthesis or nuclear fusion reactions taking place in the stars. Atoms of these elements began to fall together about six billion years ago to form a system, presently called the solar system. A part of these..

The mean distance between Earth and the Moon is about 384,400 km. Identify the distance in scientific notation. => 3.844 × 10 7 or 38.44 × 10 4 or 3.844 × 10 5 or 3.844 × 10 6..

The Titius-bode law states that the distances of the planet from the sun follow a certain pattern when expressed in 'astronomical units' (A.U). [One AU is the distance of the Earth from the sun.] The pattern is: 0.7, 1.0, 1.6, ...... Identify the pattern and use it to find the d..
