Altitude ... This term is probably known to every schoolchild.We often meet it in the newspapers, on websites, in popular scientific journals, as well as watching documentaries.
now try to give him a more precise definition.
Section 1. Altitude.General information
This term should be understood altitude or absolute mark, t. E. A coordinate in three-dimensional space, which shows the altitude in relation to sea level is a particular object.
Two other indicators of the geographic location of the object are the longitude and latitude.
Here, for example, Moscow.The altitude of the city is very different: the maximum is 255 meters (close to Art. M. "Teply Stan") and the minimum - 114.2 m - is near Besedinskih bridges, precisely where the river leaves the city of Moscow.
general, if operated purely physical measurements, the height above sea level, is nothing but the vertical distance, in fact, of the individual subject to the average level of the sea surface, which should not be disturbed by any tides or unrest.
This value can be either positive or negative.Well, everything is relatively simple: what is above the sea, becomes "plus" sign, and below, respectively, the "minus".
By the way, not to mention the fact that an increase in its value a decrease in atmospheric pressure.
If we talk about our country, the highest point of land in Russia is considered to be 5642-meter Mount Elbrus, but the lowest can be called the Caspian Sea to the absolute height of about 28 m.
Section 2. Altitude.The highest point on the planet
Well, of course, is Mount Everest - a well-known mountain, located in the central part of the mountain range of the Himalayas, just on the border of the two South Asian countries, Nepal and Tibet.
To date, its height is 8848 meters.The words "at present" is not accidental.According to scientists, the Earth's surface is still developing, so this peak, although it is imperceptible, is growing every year.
If you delve into history, almost immediately, you can find information about that first brave conquerors Chomolungma were Edmund Hillary (New Zealand) and Tenzing Norgay (Nepal).Its really a heroic climb they made May 28, 1953.Since then, Everest has become a kind of Mecca for hundreds and thousands of rock climbers, mountaineers and other daring adventurers.
Section 3. Altitude.The lowest place on the planet
In this case, a bit more complicated.The fact is that such points in the world just two: one of them - the Dead Sea - located on the land, and the second is called the Mariana Trench, and is deep under the water of the Pacific Ocean.
dwell on each of these in more detail.
Thus, the Dead Sea is known, can be found on the border of three countries: Israel, Palestine and Jordan.It is not only the most saline body of water on the planet, but the lowest portion of the land.
Now the water level in it is 427 meters, but it is not the limit, t. To. He annually, according to experts, falling by an average of 1 meter.
Altitude ... Moscow, as mentioned above, is in the range of 114 to 255 m. For us, it is, in principle, the norm.Considering the fact that the Russian capital is hardly very hilly, you feel the difference almost impossible.
And now let's take up a globe or map of the physical earth's surface: somewhere deep down in the Pacific Ocean near the island of Guam, you can see a note that says "Mariana Trench".So, he goes under water to a depth of a little more than 11 km.
