World & Physical Geography MCQs

Notes:
Mount Erebus is the second highest volcano in Antarctic. It is the southernmost active volcano on the Earth. It is the sixth highest ultra-mountain on the continent.

Notes:
The Dasht-e Kavir desert also known as the Great salt Desert, is a large desert lying in the middle of the Iranian plateau. It is the Earth’s 24th largest desert.

Notes:
The position of the Earth when it is at the greatest distance from the sun is called the Aphelion. 
The closest point to the Sun in a planet’s orbit is called perihelion.

Notes:
Pool Malebo, also known as Lake Nkunda, is located on the border between Republic of Congo and the Democratic Republic of Congo. It was formerly known as Stanley Pool. Kinshasa, capital of the Democratic Republic of Congo and Brazzaville, capital of the Republic of Congo are on the opposite side of the river on the pool. Pool Malebo lies on the lower reaches of the Congo River.

Notes:
The boundary zone when two different type of air masses meet is called a Front. The process of its formation is known as frontogenesis.

Notes:
Cyclone is any low-pressure area with winds spiralling inwards.
Conditions Favourable for Tropical Cyclone Formation include:
Large sea surface with temperature higher than 27° C,
Presence of the Coriolis force enough to create a cyclonic vortex,
Small variations in the vertical wind speed,
A pre-existing weak low-pressure area or low-level-cyclonic circulation,
Upper divergence above the sea level system.

Notes:
According to Koeppen’s  climate classification system, most parts of the peninsular plateau barring Coromandel and Malabar coastal strips is characterized by Aw (Tropical Savannah) type of climate.

Notes:
Following factors lead to the cooling of the ocean:
Back radiation in the form of long wave radiation, from the sea surface.
Exchange of heat between the sea and the atmosphere if there is temperature difference.
Evaporation: Heat is lost in the form of latent heat of evaporation
The Convectional Currents present in the earth’s interior heat the waters at the depth very fast. Thus leading to the increase in the temperature of the oceans.

Notes:
Spring Tides – When the sun, the moon, and the earth are in a straight line, the height of the tide will be higher than normal. These are called as a spring tides.
They occur twice in a month-
one on the full moon and the other on the new moon.

Notes:
Ocean currents are influenced by two types of forces namely:
primary forces that initiate the movement of water – heating by solar energy, wind, gravity and Coriolis force.
secondary forces that influence the currents to flow – Temperature difference, Salinity difference.
