Answer: Option [B]

The deflection of the winds to the right in the northern hemisphere is caused by rotation of the earth. The deflection of the wind to the right in the northern hemisphere and to Its left in the southern hemisphere is caused by the Rotation of the Earth. Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere. This deflection is called the Coriolis effect.

Answer: Option [C]

Atmospheric pressure exerted on earth is due to gravitational pull. The atmospheric pressure at the surface of the Earth is due to gravitational pull of the earth and is about 14.7 psi. That means that the weight of a column of air which has a cross section of 1 square inch and which stretches from the surface of the Earth to space is 14.7 pounds.

Answer: Option [D]

The correct answer is Tornado. A tornado is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud or, in rare cases, the base of a cumulus cloud. It has the highest wind velocity.

Answer: Option [C]

Ozone-hole in the atmosphere is largely caused by the presence of Chloro-floro-carbon. The ozone hole has developed because people have polluted the atmosphere with chemicals containing chlorine and bromine. The primary chemicals involved are chlorofluorocarbons (CFCs for short), halons, and carbon tetrachloride.

Answer: Option [D]

Speed of the wind is measured by anemometer. An anemometer is an instrument that measures wind speed. This type of anemometer has a spinning wheel. The stronger the wind blows, the faster the wheel rotates. The anemometer counts the number of rotations, which is used to calculate wind speed.
