Planet Earth has been called the “Blue Planet” due to the abundant water on its surface. Here on Earth, we take liquid water for granted; after all, our bodies are mostly made of water. However, liquid water is a rare commodity in our solar system.
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.
Antarctica and Australia. South America is mostly in the Southern Hemisphere, though the equator cuts through its northern tip.
A continent is one of Earth’s seven main divisions of land. The continents are, from largest to smallest: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
The four major domains of the earth are : – Lithosphere, Hydrosphere, Atmosphere and Biosphere.
The huge water bodies are called the ocean basins.
A continent is any of several large landmasses. Generally identified by convention rather than any strict criteria, up to seven geographical regions are commonly regarded as continents.
The solid portion of the earth is called the Lithosphere.
The Biosphere is the narrow zone where we find land, water and air together, which contains all forms of life.
where oxygen, nitrogen, carbondioxide and other gases are found. Water covers a very big area of the earth’s surface and this area is called the Hydrosphere.
