What do you understand about Atmosphere? State the layers of atmosphere?
The Earth is surrounded by a layer of gas called the atmosphere. This thin blanket of air is an integral and important aspect of the planet. It provides us oxygen for breathing and protects us from the harmful effects of the Suns’ rays.
The atmosphere extends up to a height of about 1600 km. The atmosphere is divided into five layers based on composition, temperature and other properties. These layers are – troposphere, stratosphere, mesosphere, thermosphere and exosphere.
We are living in the troposphere. The atmosphere is composed mainly of two gases – Nitrogen and Oxygen which make up 99% of clean, dry air. Nitrogen is 78%, Oxygen 21% and other gases like carbon dioxide, argon and others comprise 1% by volume. The density of the atmosphere varies with height. It is maximum at the sea level and decrease rapidly as we go up.
Give the name of continents and describe them.
There are seven major continents. These continents are:
(i) Asia: Asia is the largest continent. It covers about one-third of the total land area of the Earth. The continent lies in the Eastern Hemisphere. The Tropic of Cancer passes through this continent. Asia is separated from Europe by the Ural Mountain on the west.
(ii) Africa: Africa is the second largest continent after Asia. The equator or 0° latitude runs almost through the middle of the continent. A large part of Africa lies in the Northern Hemisphere. It is only continent through which the Tropic of Cancer, the Equator and the Tropic of Capricorn pass. The Sahara Desert, the world’s largest hot desert, is located in Africa. World’s longest river the Nile, flows through Africa.
(iii) North America: North America is the third largest continent of the world. It is linked to South America by a very narrow strip of land called the Isthmus of Panama.
