Rainwater harvesting is the process of collecting rainwater from rooftops and directing it to an appropriate location and storing it for future use. Effective rainwater management depends on the collection of rainwater and harvesting of rainwater. Irrigation of field is watering of the fields so it cannot be included in the rainwater harvesting technique.

Though there were many theories that stated the existence of Antarctica, it was only in 1820 when the human first set foot in this place. The first landing was probably just when American Captain John Davis, a sailor, set foot on the ice.

• Antarctica is the southernmost continent of the earth. It is the coldest, driest and windiest continent in the world.
  
• It has very low temperature throughout the year. The average annual temperature is −57 °C and temperature as cold as −93.2 °C is also recorded in this region.
  
• That is the reason why it is composed mainly of ice with some exposed land.
  

• Antarctica is the southernmost continent of the earth. It is the coldest, driest and windiest continent in the world.
  
• It is the continent with the highest mean elevation in the world. It has an average elevation of 7,545 feet above sea level. The elevation of Antarctica at the South Pole is 9,300 feet. The tallest mountain peak in Antarctica is Mount Vinson, which lies at a height of 16,050 feet.
  

• Largest glacier in the world is Lambert glacier. It is located in the southern most region of the earth which is Antarctica.
  
• The glacier has been measured to be 8,200 feet (2,500 meters) deep at its centre
  
• Lambert glacier moves at a rate of 400 to 800 metres per year.
  

• Antarctica is the southernmost continent of the earth. It is the coldest, driest and windiest continent in the world.
  
• It has mostly katabatic winds which means a wind that carries high density air from a higher elevation down a slope under the force of gravity.
• Such winds are sometimes also called fall winds.
  

• Antarctica is the southernmost continent of the earth. It has animals like penguins, seals, whales and other species of plants and animals.
  
• Polar bears are native to Arctic Circle.
  

• Antarctica is the southernmost continent of the earth. It has animals like penguins, seals, whales and other number of species of plants and animals.
  
• The largest animal of Antarctica is a wingless animal known as Belgica Antarctica which is 13mm or 1.3 cm long.
  
• All the other, larger, animals in Antarctica are considered marine animals.
  

• Antarctica is the southernmost continent of the earth. It is the coldest, driest and windiest continent in the world.
  
• But it was not the case before a few million years ago. It used to be tropical. There is no proper explanation behind the cooling of Antarctica. But it is believed that reduction of carbon dioxide levels led ice to be in frozen state even during Antarctica summers.
