Why do you need a compass in geography?

The concept of "compass" to every person is known since childhood, while at the lessons of natural history (now - the surrounding world), primary school teachers are introduced to this subject. Further study of the device is already more detailed in the senior classes at the lessons of geography. Compass is a device that facilitates orientation on the terrain.

The school magnetic compass is a plastic box of round shape, in the center of which there is a pin made of steel, a magnetized arrow rotates on it. The whole construction is covered with glass, and under the arrow-pointer there is a brake lever, which prevents its mobility in the non-operating state.

Main functions

Few people know that the first compass was created in China, and in Europe it appeared in the XI-XII centuries. Prior to this orientation on the terrain occurred only by natural factors.

If you ask a person what a compass is for, then perhaps, in addition to the tasks of determining the sides of the world and orienting on the terrain, he can say nothing more.

Of course, the landmark is the main function of the compass.

Compass as a means of orientation

To help the compass correctly navigate the terrain, you must remember the conditions of its use.

1. It is necessary to remove the device from the lock, which does not allow its arrow to rotate freely.
2. The arrow should automatically show north. To do this, you must turn so that 0 and 360 are connected to the direction of the arrow that points to the north.
3. It is necessary, in accordance with the map of the locality, to choose the direction for movement, by calculating the angle at which you want to move.
4. After use, the compass must be secured again.

Profession and Compass

Will everyone be able to answer questions about why a compass is needed for a person and in which professions is he an indispensable assistant? If people still give answers to the first question, then the second one already has problems.

Such professions as geologist, pilot and sailor are inextricably linked with compass knowledge, since there are no special landmarks in the deserts, the sea and in the sky. Of course, I would like to note the fact that they use not the primitive compasses with which the school introduces us, but with the special ones created for their professions. There are several types:

• Electromagnetic - to use it you need high speeds.
• The compass of aviation.
• The gyrocompass is used in the control and navigation systems of large vessels. The peculiarity of this device is that it points to the geographical North Pole, and not to the magnetic pole.
• Electronic compass. Created by the principle of determining the exact coordinates through communication with satellite systems.
• The astronomical compass. Determines the position of the stars.

Which option to choose? It all depends on the conditions under which the device will be used.

Travel and Compass

When going on a trip, do not forget to bring everything you need with you. On the question of why a compass is needed for travel, the answer is trite and simple: to return home.

Tourist hikes also can not do without a compass. Why do I need a compass for a tourist? With this simple device you can feel confident in an unfamiliar area. Because a tourist can always choose the right direction of travel.

In the modern world there is a novelty for travel enthusiasts - these are devices with built-in GPS. The only condition: before you go on a trip, try it on a familiar area to know exactly what time period its work is calculated without recharging.

Additional functions in smartphones

In the development of modern technology, smartphones with built-in compass function appeared. Why do I need a compass in an iPhone? The phone has become an integral part of human life. In the literal sense of the word with the cellular people do not part neither day nor night. The modern phones include the functions of a diary, a clock, an alarm clock, and a calendar. A smartphone is the same phone, only it is more functional. We'll figure out what the clock, calendar and compass to man are for.

A simple set consisting of a compass, clock and calendar will help you get out of a difficult situation. The clock and calendar will be helpers, so as not to get lost in time in case you have to get out of an unfamiliar place for a long time. And the compass will orient on the terrain and help in choosing the right direction of movement.

A bit about geography

Geography is a natural science that studies the Earth. In the lessons of this discipline, students not only learn what the compass in geography is for, but also receive answers to questions about its structure, rules of application. And also learn how to correctly read and draw terrain maps using this device.

On the question of what a compass is for, you can respond boldly as follows.
It is necessary for every person to be in a difficult life situation, it was easy and easy to determine the direction of the right movement.
In order to help the compass in a difficult situation, it is important to remember the following rules:

• Do not use the appliance near metal objects or electromagnetic radiation.
• Deposits of minerals can provoke the deviation of the compass needle.
• The presence of magnetic storms distorts the Earth's magnetic field.
• Do not use the appliance near another compass.
• Using a technical tool, stop and try not to change the position of your body.

Conclusion

In conclusion, it should be said that every person needs to learn how to use the compass. The choice of devices is large enough. Everyone will be able to pick up the device in accordance with their financial capabilities. And let him become a real helper.
