The 10 Different Types of Water

All I know about waterWater is a substance composed, because it is integrated by the union of atoms, two oxygen atoms are attached to a hydrogen atom, written H ² O. water is a great solvent because it can dissolve a large number of substances, including air and other gases.

The water is a liquid with not odor, taste or color. all living things depend from the water. The water is at 70% in our bodywater can be liquid, but it may be in solid form as ice and as a gas like vapor

water is the most abundant component of the earth's surface. water expands when it freezes.

Water formula Water is a chemical substance it chemical formula H2O.

. Its molecule contains one oxygen and two hydrogen atoms connected by covalent bonds.

Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state ,ice, and gaseous state water vapor.

Solid, liquid, and gas

Until the eighteenth century it was believed that water was an element, Cavendish was the English chemist who synthesized water from combustion air and hydrogen. However, the results of this experiment were not interpreted until years later, when Lavoisier proposed that the water was not an element but a compound consisting of oxygen and hydrogen, and the formula H2O.

Water is essential for the body. Therefore, the losses occurring via urine, feces, sweat and through the lungs or skin, have to recover through the water we drink and thanks to that contained in food and beverages.

Daily water needsDaily water needs

It is very important to consume enough water each day to the proper functioning of the processes of assimilation and, above all, for the disposal of cellular metabolism. We need about three liters of water a day at least, of which about half the food we get and the other half we get drinking.

To physical exercise.

When the ambient temperature is high

When we have fever.

When have diarrhea.

Do not delay in the shower

Turn off the water while brushing your teeth

Repair leaks and leaking faucets and pipes

Wash the dishes on a tray with water and not under the key

Adjust the water level in the washing machine

Wash car with bucket and sponge, not hose

Water the garden early morning or eveningnear

Do not play with water

How we can save water

Water is constantly moving. The sun heats the sea water, it makes the water evaporates and rises into the air.

This is called evaporation When raised, the water vapor cools and turns into water droplets.

These droplets fall as rain on the earth and glide through the mountains, streams and rivers, returning again to the sea.

Water cycle

Never a ship sails out of the bayBut carries my heart as a stowaway.~Roselle Mercier Montgomery, The Stowaway

I believe that water is the only drink for a wise man. ~Henry David Thoreau

The cure for anything is salt water - sweat, tears, or the sea. ~Isak Dinesen

Filthy water cannot be washed. ~African Proverb

We never know the worth of water till the well is dry. ~Thomas Fuller, Gnomologia, 1732

A lake carries you into recesses of feeling otherwise impenetrable. ~William Wordsworth

The sea pronounces something, over and over, in a hoarse whisper; I cannot quite make it out. ~Annie Dillard

The true peace of God begins at any spot a thousand miles from the nearest land. ~Joseph Conrad

Water Quotes

The specific contaminants leading to pollution in water include a wide spectrum of chemicals, pathogens, and physical or sensory changes such as elevated temperature and discoloration. While many of the chemicals and substances that are regulated may be naturally occurring (calcium, sodium, iron, manganese, etc.) the concentration is often the key in determining what is a natural component of water, and what is a contaminant. High concentrations of naturally-occurring substances can have negative impacts on aquatic flora and fauna.

Oxygen-depleting substances may be natural materials, such as plant matter (e.g. leaves and grass) as well as man-made chemicals. Other natural and anthropogenic substances may cause turbidity (cloudiness) which blocks light and disrupts plant growth, and clogs the gills of some fish species

Why we need to save waterWater is another important resource that we waste or polluteconstantly. One billion people lack access to improved water supply,and 2.400 billion lack adequate sanitation. Those without adequate water supplies and affordable are the poorest of society. To continue this scarcity in the near future, water may be source ofmany armed conflicts.

Water video in spanish

Filtered Water 6. Filtered Water. This water has passed through a fine strainer, called a filter. Some calcium and other solid substances are kept in the filter; there is no filter made which can prevent germs from passing through its fine meshes.

Soft Water 7. Soft Water. This water is soft in comparison with water which is harder.

Reverse Osmosis 8. Reverse Osmosis. This is a system of water purification which allows pre-filtered water to be forced through a semi-permeable membrane to separate impurities from our drinking water.

De-ionized Water 9. De-ionized Water. A process of exchanging "hard" ions for "soft."

Distilled Water 10. Distilled Water. This is water that has first been turned into steam so that all of its impurities are left behind.

Hard Water 1. Hard Water. This is saturated with calcium, iron, magnesium, and many other inorganic minerals. All water in lakes, rivers, on the ground, in deep wells, is classified as hard water.

Boiled Water 2. Boiled Water. Boiling helps remove some of the germs, but concentrates the inorganic minerals.

Raw Water 3. Raw Water. This has not been boiled. Raw water may be hard (as calcium hardened water) or soft as rain water. It contains millions of germs and viruses.

Rain Water 4. Rain Water. This has been condensed from the clouds.

Snow Water 5. Snow Water. This is frozen rain. Freezing does not eliminate any germs.

10 Ways to Conserve Soil

Evolution in earth

The soil structure can be established according to two different criteria. According to their chemical composition, the planet can be divided into crust, mantle and core physical properties as defined lithosphere, asthenosphere, mesosphere and the nucleus.

Soil Internal Structure

2,890–5,150 1,790–3,160 Outer core

5,150–6,360 3,160–3,954 Inner core

Soil as a complex system supports the growth of plants. Its ability to do this is not only dependent on the adequate supply of nutrients, but also upon the adequate supply of water and air. This requires sufficient pore spaces to allow plant (root) growth but at the same time provide substantial water for storage and aeration for plant respiration.

Soil texture is the classification of soil that is based on the relative proportion of the various of ultimate soil particles (i.e. sand, silt and clay). The soil texture classes include: clay, sandy clay, silty clay, clay loam, silty clay loam, sandy clay loam, loam, silt loam, silt, sandy loam, loamy sand, and sand.

Soil properties

Soil pollution is a result of many activities and experiments done by mankind and some of the leading soil pollution causes are discussed below

•Industrial wastes, such as harmful gases and chemicals, agricultural pesticides, fertilizers and insecticides are the most important causes of soil pollution.

•Ignorance towards soil management and related systems.

•Unfavorable and harmful irrigation practices.

•Improper septic system and management and maintenance of the same.

•Leakages from sanitary sewage.

•Acid rains, when fumes released from industries get mixed with rains.

•Fuel leakages from automobiles, that get washed away due to rain and seep into the nearby soil.

•Unhealthy waste management techniques, which are characterized by release of sewage into the large dumping

•grounds and nearby streams or rivers.

Contamination of soil

Soil natural resource G.O

Sand, silt, and clay are the basic types of soil. Most soils are made up of a combination of the three.

The texture of the soil, how it looks and feels, depends upon the amount of each one in that particular soil.

The type of soil varies from place to place on our planet and can even vary from one place to another in your own backyard.

Raindrop Splash and Sheet Erosion. The first step in the erosion process begins as raindrops impact the soil surface. Raindrops typically fall with a velocity of 20-30 feet per second. The energy of these impacts are sufficient to displace soil particles as high as two feet vertically. In addition, the impact of a rainfall on a bare soil can compact the upper layer of soil, creating a hard crust that inhibits plant establishment.

Soil Erosion Process

Soil pH: The contamination of soil by addition of acidic or basic pollutants and acid rains has an adverse effect on the pH of soil.

Water the soil: We water plants, we water the crops, but do we water the soil? If the answer is negative, it is high time we adopt the method of watering soil as a measure of conserving soil.

Salinity management: The salinity of soil that is caused by the excessive accumulation of salts, has a negative effect on the metabolism of the crops in soil.

Soil organisms: Organisms like earthworms and others benefiting the soil should be promoted.

Indigenous Crops: Planting of native crops is known to be beneficial for soil conservation.

Plant trees: We all know that the roots of trees firmly hold on to the soil.

Terraces: Terracing is one of the very good methods of soil conservation.

No-till farming: When soil is prepared for farming by ploughing it, the process is known as tiling. No-till farming is a way of growing crops without disturbing it through tillage.

Contour ploughing: This practice of farming across the slopes takes into account the slope gradient and the elevation of soil across the slope. Crop rotation: Some pathogens tend to build up in soil if the same crops are cultivated consecutively.
