Chapter 5 Major Domains of the Earth
- In earth, there are three components of environment: Lithosphere, Atmosphere and Hydrosphere.
- Solid portion of the earth is lithosphere, water portion of the earth is hydrosphere and air portion of the earth is known as atmosphere.
- The narrow zone of contact between air, water and land is called biosphere.
- The large landmasses are continents and large water bodies are oceans.
- There are seven continents on earth: Asia, America, Africa, North America, South America, Australia and Antarctica.
- Research stations of India in Antarctica are Maitri and Dakshin gangotri.
- More than 71% of Earth’s surface is covered with water and 29% with land.
- There are five oceans on the Earth: Pacific Ocean, Indian Ocean, Arctic Ocean, Antarctic Ocean and Atlantic Ocean.
- Mariana Trench in Pacific Ocean is the deepest point on Earth.
- Indian Ocean is the only Ocean which is named after a country ‘India’.
- 78% of Nitrogen is present in atmosphere, 21% oxygen and 1% other gases like CO2, argon, vapours etc.
- The largest continent is Asia and smallest is Australia. The largest Ocean is Pacific ocean and smallest is Arctic ocean.
- Increase in the amount of CO2 increases global temperature and this is called as global warming.
