Introduction About The Earth:
Earth offers many natural resources that help us to live. Earth is a special place. It has many physical features, such as mountains, beaches, plains, deserts, islands, peninsulas, oceans and rivers. The weather can vary each day and from place to place.
Types Of Vegetation:
There are different types of soil and vegetation (plants). Many animals roam around Earth. All of these things make up our natural environment. The natural environment provides many natural resources for people. Natural resources are always found in or on Earth. The basic natural resources are water, air, soil, minerals, animals and plants.
The air around us is a mixture of gases, mainly nitrogen and oxygen, but containing much smaller amounts of water vapor, argon, and carbon dioxide, and very small amounts of other gases.
Water is essential for all living things, plants and animals. All organisms need water to maintain life processes. Some organisms live in water, some others breed only in water. Though the amounts of water required are different for different organisms, none can do entirely without it.Humans cannot live without food and water. One third of Earth’s surface is desert which supports very few people.
Mountains are areas higher than the surrounding areas which were formed due to the tectonic movements, earthquakes, volcanic eruptions and even due to the erosion of the surrounding areas caused due to wind, water and ice.
Valleys are flat areas between hills and mountains and are caused due to the actions of glaciers and rivers over millions of years.
The desert is a dry piece of land with little or no vegetation due to lack of adequate rainfall. They are found mainly in rain shadow areas.
A natural elevation of the earth’s surface, typically rounded and smaller than a mountain.
