We live on the planet Earth - the most beautiful in the solar system.Man using the means at hand and mind, far from able to step in its development, not only physically, but also to learn and explore the surrounding environment, built large cities with well-developed infrastructure and various equipment.So what helps people to build and maintain their way of life to create an artificial environment?It's no secret that the land - this is the part of the earth, on which man lives, using the resources necessary for their well being and development.
Let's see
Digging Deeper.So, the land - is the main habitat of people.It covers part of the land, and it is actively developing organisms, from bacteria, and ending with a variety of animals, as well as the man himself.The land area on Earth (including continents and islands) is 148,940,000 square kilometers, the rest of the place, more than 70 percent, occupy the sea, the oceans.
meaning of the word in all dictionaries of the world the word "land" the same - the opposite of the water.Man consists of flesh and bone in the same way as our planet is composed of land and water only at the cellular level.See how we are connected with nature.And certainly people living on Earth, there is not just.Maybe in time we still know all the secrets of our existence.
Land - a place on the Earth's surface, where for a long time people adapted to survive, learned to hunt large animals, and eventually mastered agriculture, growing a variety of crops (grains, vegetables and fruits).Therefore, the land - not just home to humans, but also "nurse."Do not be a surface on which trees and shrubs, live animals, people massively build their own home and hide them from the difficult climatic conditions, then all would be living in the aquatic environment.
But the sea and the land are inextricably linked.These are two powerful elements.Without them, life is impossible on Earth because we live on the land and eat, and with the help of liquid to quench thirst, to water their crops, prepare food and monitor their hygiene.The water is very salty seas, and use it for food can not be the same as using it to grow crops.So we use the liquid from the lake (Onega, Lake Baikal, Ladoga, and hundreds of others) and rivers.They are fresh water from nature.Earlier people used that liquid that falls from the sky, that is, rain and snow.
Many scientists are still arguing about the origin of water on Earth.Geologists put forward their version of it lies in the fact that once upon a time, millions of years ago, our planet was attacked huge comets and asteroids.They are, according to geologists, contain water.And in this way the deep oceans appeared on Earth.
In conclusion
Based on the foregoing, we can determine exactly what the land - it is the surface of the crust of the planet's surface and are not covered by oceans, seas, lakes and rivers.Any portion of the island or the mainland, which is not flooded with surface water of any water body would fall under this definition.
