Explanation Text Global Warming
As we know now, global warming which is happening right now has a very big impact on natural conditions, animals and humans. Well, do you know how global warming which has a particularly serious impact on life happens? To know the process of how this phenomenon occurs, see the following explanation.
The process starts when sunlight shines the earth where most of the heat is absorbed by the earth and a half of it is reflected back onto the air (atmosphere). Sunshine returning to the air is trapped by gases in the atmosphere such as carbon dioxide, sulfur dioxide, methane, water vapor, and so on. This event is known as the greenhouse effect.
Solar radiation on the earth's atmosphere makes ozone layer get thinner and makes the sunlight which shines the Earth become hotter. The greenhouse effect also causes the sunlight which is reflected back onto space is reflected back into the earth. This phenomenon causes the earth continuously getting hotter. This condition is known as global warming.

Respiratory System
Do you know how your body gets oxygen from the air and removes carbon dioxide from your body? Right! It’s because of the respiratory system. Do you know how it works? The following explanation is written to help you understand the process clearly.
The first phase of respiration is breathing in or inhalation. This process brings air from outside the body into the lungs. From the lungs, the oxygen moves through blood vessels to the heart which then pumps the oxygen-rich blood to all parts of the body. Oxygen then moves from the blood-stream into the cells, which completes the first phase of respiration. In the cells, oxygen is used in a separate energy-producing process which produces carbon dioxide as a byproduct.
The second phase of respiration begins when the carbon dioxide moves from the cells to the bloodstream which carries carbon dioxide to the heart. Then, it pumps the carbon dioxide-laden blood to the lungs. In the lungs, breathing out or exhalation removes carbon dioxide from the body, thus completing the respiration cycle.

How a Kite is Flying – Example Of Explanation Text:
A kite is an object which is made from a light material stretched over a frame. Due to its light material a kite will lift off the ground and fly when it is tilted into the wind.
A kite is uses wind to make it fly because it is heavier than air. When wind travels over the surface of the kite, it is split into two streams of air. One stream of the air goes over the kite while the second stream goes under the kite.
The upper stream creates an area of low pressure above the kite. The lower stream hits the kite at a shallow angle and creates an area of high pressure.
The high pressure area has a pushing effect while the low pressure area has a pulling effect. The combination of push and pull can creates enough force to lift the kite into the air.
Kites have been known for thousand of years. They are used for military or scientific purposes. Todays kites are much used for leisure and competition.
