Nature Force: How is electricity generated from solar energy?

The sun is the source of all energy either in the form of fossil fuels or wood. After all, these substances have made from the energy of the sun and have stored energy. However, the heat of the sun can be used directly in the form of solar energy. Solar cells and giant solar plants are used for generating electricity. it has been estimated that the solar energy reaching the Earth's surface in one year is double than we will ever receive from all the Earth resource of coal, oil, natural gas, and uranium together.  Solar Plant In China                                        How can we capture the heat energy of the sun? The easiest way to capture the heat energy of the sun is to heat water. In countries with a regular supply of abundant sunlight, the roofs of the houses have tanks with water that gets heated by the sunlight. 'Solar houses' can now be seen in various countries across the world. Solar collectors are placed on the roofs of these houses, whic

Our Environment- Which Animal Live In The Steppes & The Savannas

The steppes and the savannas are the great grasslands of the earth. Savanna grasslands lie between the tropical rainforest and the deserts in the northern as well as the southern hemisphere. Trees like the acacia and the water storing baobab grow in the savannas. In addition to these plants, gnus, giraffes and antelopes are found here. countless flamingos stand in the sea and one can see bald-headed vultures in the sky. In contrast, the steppe grasslands like the pampas of South America and prairies of North America are found in the middle of the continents. They are dry, devoid of trees, and cold in winter. Do Bison still exist in the prairie? Today there are around 4000,000 bison in the Northamerica steppes, but they had almost become extinct about 120 years ago. At that time the few remaining animals were transferred to the Yellowstone National Park in North America to protect them.  Bison look docile Bison are nomadic grazers and are usually peaceful, unconcerne

HUMAN BODY- WHAT KEEPS US HEALTHY

A lot of thing can keep us healthy: Sleep, Exercise, Fresh Air, Friends, Healthy Food. Eating healthy food means not eating too much and not eating the same thing always. Our food is composed of three components: fats, carbohydrates, and proteins. Carbohydrates like sugar and starch, are present in potatoes. We also need vitamins and minerals, such as salt or calcium, to stay healthy. We need to brush our teeth often and keep ourselves clean to keep away the bacteria and remain healthy. Why are vitamins necessary in diet? Vitamins assist the body in utilizing the nutrients. They are not suppliers of energy like fats or carbohydrates, but help the body in absorbing minerals such as calcium, magnesium, or sodium contained in salt and transporting them to required places. Vitamins also help in the correct functioning of enzymes that help convert food into components useful for the body. Since the body cannot synthesize vitamins, they need to be supplied from outside.

Difference Between Asteroids,Comets and Meteors?

Hello Everyone! This would be my first post as a blogger and I am very much thrilled to write something that I know well (I guess??). Eventually all my feature blogs will come from; reading books, blogs, newspaper, magazines, novels, papers etc. So some of you may find my information already read by or something like that. But I will try to give you some extra knowledge/information that you may find different. now a days there are so many ways to collect information, but someone can find it difficult to explore all the database. Here I will try my best to give you information that will benefit you in any aspect of life. One reason for taking this topic was, few days ago I and my child witness ( I don't know how many of you watch that??) natures magical phenomenon in sky: The Meteor Shower. My child was very frightened to see that because he thought that if there is shower/fire like event in the sky, so we all will be dead or get vanished like dinosaurs, a
