How can wind be used to produce electricity?
Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind turns the propeller-like blades of a turbine around a rotor, which spins a generator, which creates electricity.

How should the wind come?
Because of the way Earth rotates, solar light rays heat some parts of Earth’s surface more than others. Air at hot spots rises and expands, leaving low pressure beneath it. Air at cold areas cools and falls, creating high pressure. When high-pressure air rushes into a low pressure area, that rush of air is WIND!

What is the biosphere made of?
The biosphere is made up of the parts of Earth where life exists—all ecosystems. The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet.
Is wind a oxygen?
Simply put, wind is the motion of air molecules. Air comprises molecules of nitrogen (about 78 percent by volume), oxygen (about 21 percent by volume), water vapor (between 1 and 4 percent by volume near the surface of the earth) and other trace elements….
Which is the domain where life exists?
According to this system, the tree of life consists of three domains: Archaea, Bacteria, and Eukarya. The first two are all prokaryotic microorganisms, or mostly single-celled organisms whose cells have no nucleus. All life that has a cell nucleus and eukaryotic membrane-bound organelles is included in Eukarya.
What is the biosphere example?
The biosphere is defined as the area of the planet where organisms live, including the ground and the air. An example of the biosphere is where live occurs on, above and below the surface of Earth. The part of the Earth and its atmosphere capable of supporting life.
Does biosphere mean life?
Biosphere, relatively thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. The biosphere is a global ecosystem composed of living organisms (biota) and the abiotic (nonliving) factors from which they derive energy and nutrients.

Why is the biosphere important?
The biosphere is defined as the zone where both living organisms and the products of their activities are found. So it plays an important role to maintain the ecosystems, that is the life of organisms and their mutual interactions. And biosphere is very important to regulate the climate.
What are the two major elements of biosphere?
Biosphere has three basic components. These are (A) abiotic (physical and inorganic) components; (B) biotic (organic) components and (C) energy components. Let us discuss about these three components in detail.
What is biosphere in a sentence?

How many kinds of winds are there?
What causes wind class 9th?
Ans: The uneven heating of the earth’s surface is the main cause for the winds. On being heated more the air raises up and hence low pressure is created. Hence, the air in high pressure occupy the low-pressure region causing the wind….
What is Biosphere very short answer?
The biosphere is a narrow zone of the earth where land, water, air interact with each other to support life. It is in this zone that life exists. There are several species of organisms that vary in size from microbes and bacteria to large mammals.
