PLANETS

Mercury.

Is the innermost planet in the Solar System. It is also the smallest, and its orbit is the most eccentric (that is, the least perfectly circular) of the eight planets.

Venus.
Is the second planet from the sun in order of distance from the Sun, and the third in terms of size, from smallest to largest. It is named in honor of Venus, the Roman goddess of love. It is a rocky planet Earth type, often called the Earth's sister planet because both are similar in size, mass and composition, but totally different in thermal and atmospheric issues.

Earth.

Is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. It is also the largest of the Solar System's four terrestial planets. It is sometimes referred to as the world, the Blue Planet.

Earth formed 4.54 billion years ago, and life appared on its surface within one billion years. The planet is home to millions of species, including humans.

Mars.
Is the fourth planet from the Sun in the Solar System. Named after the Roman God of War, it is often described as the "Red Planet", as the iron oxide prevalent on its surface gives it a reddish appearance. Mars is a terrestial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth.

Jupiter.
Is the fifth planet from the Sun and the largest planet within the Solar System. It is a gas giant with mass one-thousandth that of the Sun but is two and a half times the mass of all the other planets in our Solar System combined. Jupiter is classified as a gas giant along with Saturn, Uranus and Neptune. Together, these four planets are sometimes referred to as the Jovian or outer planets.

Satrun.
Is the sixth planet from the Sun and the second largest planet in the Solar System, after Jupiter. Named after the Roman god Saturn, its astronomical symbol (♄) represents the god's sickle. Saturn is a gas giant with an average radius about nine times that of Earth. While only one-eighth the average density of Earth, with its largervolume Saturn is just over 95 times as massive as Earth.

Uranus.
Is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. It is named after the ancient Greek deity of the sky Uranus, the father of Cronus (Saturn) and grandfather of Zeus (Jupiter). Though it is visible to the naked eye like the five classical planets, it was never recognized as a planet by ancient observers because of its dimness and slow orbit.

Neptune.
Is the eighth and farthest planet from the Sun in the Solar System. It is the fourth-largest planet by diameter and the third largest by mass. Neptune is 17 times the mass of Earth and is somewhat more massive than its near-twin Uranus, which is 15 times the mass of Earth but not as dense. On average, Neptune orbits the Sun at a distance of 30.1 AU, approximately 30 times the Earth–Sun distance.

Earth SOS

Concept of Environment.
Environment, abiotic itemset (solar, soil, water and air) and biotic (living organisms) that make up the thin layer of the Earth called biosphere, livelihood and home living.

COMPONENTS OF ENVIRONMENT.
The air, which protects the earth from ultraviolet radiation and excess allows the existence of life is a gaseous mixture of nitrogen, oxygen, hydrogen, carbon dioxide, water vapor, other elements and compounds, and dust particles. Warmed by the sun and the Earth's radiant energy, air circulates around the planet and modifies the thermal differences. In regard to water, 97% is in the oceans, 2% is ice and the remaining 1% is fresh water from rivers, lakes, groundwater and atmospheric humidity and soil. Soil is the thin mantle of matter that sustains life on Earth. It is the product of the interaction of climate and bedrock or bedrock, as glacial moraines and sedimentary rocks, and vegetation. Of these depend living organisms, including humans. Plants use water, carbon dioxide and to convert sunlight carbohydrate feedstocks through photosynthesis; animal life, in turn, depends on plants in a sequence of links interconnected network known as trophic .

During its long history, the Earth has changed slowly. Continental drift (result of plate tectonics) separated land masses, oceans and land invaded withdrew from it, and rose and eroded mountains, depositing sediment along the coast (see Geology). Climates flared and cooled, and appeared and disappeared lifestyles changing environment. The latest major environmental events in Earth's history occurred in the Quaternary, during the Pleistocene (between 1.64 million and 10,000 years ago), also called glacial period. The subtropical climate disappeared and changed the face of the northern hemisphere. Large ice sheets advanced and retreated four times in North America and three in Europe, swinging the cold to temperate climate, influencing plant and animal life and, ultimately, leading to the climate we know today. Our was received, either the names of recent postglacial and Holocene. During this time the global environment has remained more or less stable.

Tips to protect our environment:

1.-If we take care of the planet, we will can live more.

2.-If we not throw garbage, we will have a most cleanest planet.

3.-If we walk more, so there will be no contamination.

4.-If there were no wars, the earth will be cleanest.

5.-If we do not waste water, we will have more in the future.

6.-If we campaign on pollution, all the people are interested in save the planet.

7.-We will be fine, if we take care the planet.

8.-We will clean the planet, if we can clean our home.

9.-If we help the animals, we will have more nature.

10.-If we reduce the use of factories, we will have more time ozone.

Water

Basics:

Water is the main and indispensable component of the human body. Human beings can not be without drinking more than five or six days without endangering his life. The human body is 75% water at birth and about 60% in adulthood. Approximately 60% of this water is in the interior of the cells (intracellular water). The rest (extracellular water) is flowing in the blood and bathes the tissues.

In combustion reactions occurring nutrients inside cells produce energy for small amounts of water. This formation of water is greater by oxidizing fats - 1 gr. of water per gr. fat - that starches -0.6 gr. per g. of starch. The water produced in cellular respiration is called metabolic water, and is essential for animals adapted to desert conditions. If camels can withstand months without drinking is because they use the water produced by burning stored fat in their humps. In humans, the production of metabolic water with a normal diet is as little as 0.3 liters per day.

As shown in the following figure, the body loses water through different channels. This water has to be recovered by offsetting losses with intake and avoiding dehydration.

Statements:

1.- If we do not waste water, everyone would not need water.
2.- If you see somone wasting water, go with him and tell him that we need to take care of the water.
3.- If someone drinks water with toxic waste, you risk dying.
4.- If the water ran out in the world, there would be no life.
5.- If you take care of the water, look after your life.
6.-If you pollute the water would be over nature.
