World & Physical Geography MCQs

Notes:
A rough and barren landscape of relict and largely uneroded lava fields is called Malpais. Malpais in Spanish means ‘badland’. It is a characteristic of an arid environment.

Notes:
Tasmania is an island state of Australia. It lies to the south of the Australian mainland separated by the Bass Strait. It is the 26th-largest island in the world. It houses several national parks and World Heritage Sites.

Notes:
Banff National Park is Canada’s first national park. It houses Rocky Mountains peaks and turquoise glacial lakes. It is a part of the Canadian Rocky Mountain Parks UNESCO World Heritage Site. It can also be called Canada’s oldest national park, established in 1885. It houses the Valley of Ten Peaks. This national park has a subarctic climate with montane, subalpine and alpine ecoregions.

Notes:
The Thermosphere is located between 80 and 400 km above the mesopause. It contains electrically charged particles known as ions.It is therefore known as Ionosphere. The temperature here starts increasing with heights. Radio waves transmitted from the earth are reflected back to the earth by this layer.

Notes:
Lake Albert of Africa is located on the border between Uganda and the Democratic Republic of Congo. It is one of Africa’s Great Lakes. It is formerly known as Lake Mobutu Sese Seko. It is located in Albertine Rift, which is the western branch of East African Rift. The primary inflows of this lake are Victoria Nile and Semliki River.

Notes:
Frontal precipitation occurs when a front or boundary line is formed between two air masses of contrasting temperature. Along the fronts, the warm air rises above the denser cold air. The mid-latitude regions experiencing the convergence of warm tropical and cold polar air masses are important areas receiving frontal precipitation.

Notes:
Of all the major oceans in the world, the Atlantic Ocean is the saltiest. The high surface salinity in the Atlantic is maintained by two processes:
the Agulhas Leakage/Rings, which brings salty Indian Ocean waters into the South Atlantic and
“Atmospheric Bridge”, which evaporates subtropical Atlantic waters and exports it to the Pacific

Notes:
The Arctic Ocean is the smallest and shallowest of the world’s five major oceans. It is also known as the coldest of all the oceans. Its salinity is the lowest on average of the five major oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.

Notes:
Coral are made up of genetically identical organisms called polyps. These polyps have microscopic algae called zooxanthellae living within their tissues.
The corals and algae have a mutualistic relationship.

Notes:
Porosity – The volume of water which can be held within a soil is called its porosity. It is expressed as a ratio of volume of voids (pores) to the total volume of the material.
