Climate, Weather, and Geography

Nimbus is the scientific term for rain clouds or clouds that produce precipitation. In meteorology, nimbus clouds (such as nimbostratus or cumulonimbus) are characterized by their dark appearance and ability to produce rain or snow. The other options (Rift water, Fog mid, Abattoir) are not meteorological terms related to rain clouds.

It is correct this is also known as terminus, it is where glacier first starts melting.

Desert sand has low specific heat capacity and cannot retain heat effectively, so it radiates heat back to the atmosphere very quickly after sunset. Plains have vegetation and soil that hold heat longer, keeping nights warmer. Clear desert skies allow rapid heat escape without cloud cover.

During winter in India, winds blow from land to water (specifically from the cold landmass of northern India toward the warmer Indian Ocean). This creates the dry northeast monsoon conditions when high pressure over the continent pushes air outward toward the relatively warmer oceanic regions.

During winter, southern India experiences the highest temperatures due to its proximity to the equator. The northern plains are much colder during winter months because they are farther from the equator and experience cold winds from the Himalayas.

A sudden fall in barometric pressure indicates approaching stormy weather. Low pressure systems are associated with storms, clouds, and precipitation, while high pressure systems bring fair weather. Rapidly dropping pressure signals an approaching low-pressure system or storm front.

El Nino causes unusual warming of Pacific waters near South America, leading to heavy rainfall there and drought conditions in Australia/SE Asia. This is a reversal of normal patterns. Option A correctly captures this inverse relationship.

Cyclones are called 'hurricanes' in North America. The same weather phenomenon is called 'typhoons' in the Northwest Pacific, and 'cyclones' in the Indian Ocean and South Pacific. 'Tornadoes' are a different phenomenon entirely.

Water expands when it freezes (unlike most materials). This expansion creates immense pressure inside pipes, causing them to burst. Pipes don't contract and break, nor does rust cause sudden bursting at night.

Storms are associated with low-pressure systems. When atmospheric pressure falls suddenly, it indicates the approach of a storm system. Rising pressure generally indicates fair weather, while falling pressure signals deteriorating weather conditions.

Snow’s albedo is highest.

Rotation of Earth causes wind to deflect towards left in the southern hemisphere.

The central Asian steppes run through Kazakhstan, Turkrnenistan, Uzbekistan and Mongolia. The climate here is harsh with dust storms, little to no rainfall and temperature ranging from – 4 to 50 degree Celsius.

The first statement is correct. One major factor affecting the distribution of the temperature of Earth is distribution of land and oceans. The moderating effect on temperature of the land due to proximity of the sea is called Maritime influence.

Planetary winds are large-scale atmospheric circulation patterns that blow across the Earth's surface. Trade winds are permanent planetary winds that blow from the subtropical high-pressure belts toward the equatorial low-pressure zone. While monsoons are also planetary (seasonal) winds, trade winds are the classic example cited in textbooks. Land and sea breezes and Chinook are local winds, not planetary.
