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.
The various rocks and soils in nature are also very important resources in the eco-system. These soils come in quite a number of samples such as loamy soils, sandy soils and clay soils. The clay soils are majorly used for pottery works. The sandy soils on the other hand are very essential in building and construction works as they are used as binding agents together with the cement.
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.
Finally is a force known as magnetism. This force basically originates from the earth and rotates around the earth from one pole to the other. Other naturally occurring magnets in nature are the lodestone rocks. These rocks posses all the qualities of a magnet as well. They attract other magnetic substances towards them.
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.
