Question : In what type of rainfall do winds move out of a high-pressure area, with wind direction clockwise in the northern hemisphere and anti-clockwise in the southern hemisphere?
Option 1: Orography
Option 2: Cyclones
Option 3: Anticyclone
Option 4: Convection
Correct Answer: Anticyclone
Solution : The correct answer is Anticyclone.
An anticyclone is a meteorological phenomenon characterised by a large-scale circulation of winds around a central area of high atmospheric pressure. In the Northern Hemisphere, the winds rotate clockwise, while in the Southern Hemisphere, they rotate anticlockwise when viewed from above, opposite to the rotation of a cyclone.

Question : Choose the incorrect statement related to monsoon.
Option 1: The southwest monsoon winds blow over the warm oceans, gather moisture and bring widespread rainfall over the mainland of India.
Option 2: The intensity and position of the high-pressure area, east of Madagascar, affect the Indian monsoon.
Option 3: The difference in pressure over Tahiti (Pacific Ocean), and Darwin in northern Australia (Indian Ocean) is computed to predict the intensity of the monsoons.
Option 4: The western cyclonic disturbances occur due to withdrawal or the retreat of the monsoon.
Question : Select the correct statement regarding the Indian monsoon.
Option 1: A monsoon is a seasonal shift in wind direction. It can cause very low rainfall during the summer and heavy rainfall in the winter
Option 2: A monsoon is a sudden temperature change. It can cause moderate rainfall during the summer and dry spells in the winter
Option 3: A monsoon is a seasonal shift in wind direction. It can cause heavy rainfall during the summer and dry spells in the winter
Option 4: A monsoon is a seasonal shift in wind direction. It can cause moderate rainfall during the summer and no rain in the winter
Question : The equator represents:
Option 1: line joining the north and south poles.
Option 2: imaginary line passing around the Earth midway between the Northern Hemisphere and Southern Hemisphere.
Option 3: line joining tropic of cancer and tropic of Capricorn.
Option 4: the axis of rotation of the Earth.
Question : Flat footed camels can walk easily in sandy deserts because:
Option 1: pressure on the sand is decreased by increasing the area of the surface in contact
Option 2: pressure on the sand is increased by increasing the area of surface in contact
Option 3: pressure on the sand is decreased by decreasing the area of the surface in contact
Option 4: pressure on the sand is increased by decreasing the area of the surface in contact
Question : Which of the following regions have long, cold winters with high winds and average temperatures below freezing for six to ten months of the year?
