World & Physical Geography MCQs

Notes:
Copernicus proposed Helio-centric model. According to this model, sun stands at the center of the universe, and Moon, the Earth, and remaining planets revolve around the sun.

Notes:
Planetary or permanent winds blow from high pressure belts to low pressure belts in the same direction throughout the year. They never change the direction. They blow over vast area of continents and oceans. They are easterly and westerlies and polar easterlies.

Notes:
Some Important Local Winds: 
1- Chinook- Hot, dry wind in Rockies, also called `snow eater`.
2- Foehn- Hot, dry wind in the Alps
3- Khamsin- Hot, dry wind in Egypt.
4- Sirocco- Hot, moist wind from Sahara to Mediterranean Sea
5- Solano- Hot, moist wind from Sahara towards Iberian Peninsula
6- Harmattan- Hot, dry wind blowing outwards from the interior of W.Africa, also called Guinea Doctor.
7- Bora- Cold, dry wind blowing outwards from Hungary to the north of Italy (near Adriatic Sea).
8- Mistral- Very cold wind, which blows from the Alps over France
9- Punas- Cold, dry wind blowing down towards the western side of Andes.
10- Blizzard- Very cold winds in Tundra region
11- Purga- Cold wind in Russian tundra
12- Levanter- Cold wind in Spain
13- Norwester- Hot wind in New Zealand
14- Santa Ana- Hot wind in S. California in USA.
Kikuyu,  is most populous ethnic group or tribe of Kenya

Notes:
The city with the summer season from December to March, the Coordinated Time being 2 hours ahead of Greenwich Mean Time, and famous beaches with Heaviside’s dolphins as an attraction that are endemic to the region is likely to be Durban, South Africa. Durban is located on the east coast of South Africa and is known for its warm subtropical climate, long sandy beaches, and vibrant cultural heritage. Heaviside’s dolphins are a small species of dolphin that are found only along the coast of South Africa and Namibia and are a popular attraction for tourists visiting Durban.

Notes:
Mean elevation is 7516 ft and it is the continent with highest mean elevation.

Notes:
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub- surface layers. Organisms living in this zone are called benthos. They generally live in close relationship with the substrate bottom; many suchorganisms are permanently attached to the bottom.

Notes:
The Kuroshio is a north-flowing warm ocean current on the west side of the North Pacific Ocean. It is similar to the Gulf Stream in the North Atlantic Ocean.

Notes:
Moving to equator results in less disturbance for wildlife in that area. Much of the biodiversity around the equator is in the rainforest. As stated before, geographic isolation drove speciation around the equator, increasing the overall uniqueness and amount of species.

Notes:
Nuclear fusion is the source of Sun’s energy. At the core where temperature and pressure are very high hydrogen atoms fuse into helium atom and release energy in the form of Gama rays.

Notes:
The main chemicals in air pollution that create acid rain are sulfur dioxide (SO2) and nitrogen (NOx). Acid rain usually forms high in the clouds where sulfur dioxide and nitrogen oxides react with water, oxygen, and oxidants. this mixture forms a mild solution of sulfuric acid and nitric acid.
