Concept: 

• Every region has a different house.
• The type of house depends on the climatic conditions in the region. 
• Houses are built specially to suit the needs of the people.​

Explanation:

Igloo:

• The Eskimos make their houses out of ice called an igloo.
• Since the air between the ice walls prevents the inside heat from escaping.
• Snow is believed to be a good insulator of heat and traps it.
• Igloos are temporary winter homes mainly found in Canada.
• Eskimos are the people living in the Arctic and subarctic regions of the US, Russia, Canada, and Greenland.
• In India, tourists can experience igloos in Manali in the winter season.

Thus, the house made of snow is known as Igloo.

Rain Basera:

• Rain Basera or common shelter (sometimes called as the Night shelter) is a place created by the Government or NGOs for the homeless.
• It is a place where the homeless find shelter.

Green house:

• A greenhouse looks like a small glasshouse and is used for growing plants, especially during winter.
• In a greenhouse, the glass panel lets the light in but does not allow heat to escape.
• Therefore, the greenhouse warms up, very much like inside a car that has been parked in the sun for a few hours. 
• The term ‘Greenhouse effect’ has been derived from a phenomenon that occurs in a greenhouse.
