We live on planet Earth - the most beautiful planet in the solar system. Man, using improvised means and mind, was able to take a long step in his development, not only physically, but also, having mastered and studied the environment, he built large cities with a well-developed infrastructure and various equipment. So what helps people to build and maintain a habitual way of life in the created artificial environment? It is no secret to anyone that land is exactly that part of the Earth on which a person lives, using the resources necessary for his prosperous existence and development.
Let's figure it out
Dig deeper. So, land is the main habitat of people. It covers part of the earth, and living organisms are actively developing on it, ranging from bacteria to various animals, as well as man himself. The land area on planet Earth (including continents and islands) is 148,940,000 square kilometers, the rest, more than 70 percent, is occupied by seas and oceans.
Meaning of the word
In all dictionaries of the world the meaning of the word"land" is the same - the opposite of water. Man is made of flesh and blood just like our planet is made of land and water, only at the cellular level. See how we are connected with nature. And for sure, people living on Earth did not appear just like that. Maybe in time we will learn all the secrets of our existence.
Land is that place on the surface of the Earth where a very long time ago a person adapted to survive, learned to hunt large animals, and eventually mastered agriculture, growing various crops (grain, vegetables and fruits). Therefore, land is not only a home for a person, but also a “nurse”. If there were no surface on which trees and shrubs grow, animals live, people massively build their own dwellings and hide in them from difficult climatic conditions, then everyone would live in the aquatic environment.
But sea and land are inextricably linked. These are two powerful elements. Without them, life on planet Earth is impossible, because on land we live and eat, and with the help of liquid we quench our thirst, water our crops, cook food and monitor our hygiene. In the seas, the water is very s alty, and it is impossible to use it for food, just like growing crops with it. Therefore, we use liquid from lakes (Onega, Baikal, Ladoga and hundreds of others) and rivers. They have natural fresh water. Previously, people used the liquid that falls from the sky, that is, rain and snow.
Many scientists are still arguing about the origin of water onplanet Earth. Geologists have put forward their version, it lies in the fact that once upon a time, millions of years ago, our planet was attacked by huge comets and asteroids. They, according to geologists, contained water. And that is how deep oceans appeared on Earth.
In conclusion
Based on the above, we can accurately determine that land is the surface of the earth's crust or part of the planet's surface that is not covered by oceans, seas, lakes and rivers. Any area of the mainland or island, the surface of which is not flooded with the water of any body of water, falls under this definition.
