There are very many substances that make up the planet that we live in. Many of these things are very essential resources while others can be quite dangerous if mishandled in any way. Water is one of the most profound materials on the planet. It is not only found in the numerous water bodies but also underneath the earth crust this element flows freely. The methods of protection from electromagnetic fields are numerous.
Many of the substances on the earth are both visible and tangible in nature, this however is not so for air. Air is basically a mixture of several gases that float around in space due to their weightlessness. They are also colorless and hence invisible to the naked human eye. When in motion air is referred to as wind. Wind can be harnessed using mills to source out energy that can be used in numerous ways.
Other important things in nature include the plants. These grow about randomly in nature and have numerous importances as well. The most important thing about these plants is that they create food for the humans and many other living creatures that depend on vegetables as food. This food is created during a process commonly known as photosynthesis. Here plants make use of the chlorophyll in their lives to make food reserves.
In the beginning the earth was simply one big rock or at least scientists claim so. This rock was subjected to the numerous corrosive forces in nature and it gradually broke down. This process went on for so long until there were finally fine textured pieces of rocks and these were called soils. Due to the difference in texture and other qualities as well the soils come in various kinds including clay, loamy, sandy soils and others.
Within the crust of this earth are also numerous other vital materials to the survival of man. These include the various kinds of rocks that are considered quite valuable in society. Many of these are metal ores and can be refined to get metallic elements such as iron, silver, gold, copper and numerous other precious substances. There is also a particular kind of rock known as lodestone. This is a very unique kind of stone.
When talking about nature, there are numerous other intangible things that cannot be left out. These include the various forces in nature that make the world the complete place that it is. Gravity is one of those forces. The gravitation force of pull tends to return all things from the earth to the earth. This force has numerous application in nature.
These magnets have widely been used in the creation of direction mechanisms. This works due to the fact that the earth is the biggest natural magnet and any other magnet in the force field of the earth will align its diatoms in an opposite polarity to that of the earth. This theory helps navigators to use compass needs to situate the magnetic north and south while at sea.
Hospitals also use electromagnetism to diagnose patients. They are also used in the removal of metallic objects out of the human body especially after the occurrence of accidents. These magnetic radiations can however be very harmful if the person is exposed to them for a very long time. There are protective gears that have been designed to cater for this.
