Climate, Weather, and Geography

A blizzard is characterized by strong winds combined with falling or blowing snow that reduces visibility. The key features are the blinding nature of the snowfall and the presence of strong icy winds, which distinguishes it from regular snowstorms. Desert winds carry dust, not snow, and polar winds may pick up ice particles but do not necessarily involve falling snow.

Geostrophic winds occur when the pressure gradient force is balanced by the Coriolis force caused by Earth's rotation. This deflection due to rotation is the key characteristic that separates geostrophic winds from other wind types like trade winds or westerlies, which are named primarily by their location and general circulation patterns.

The Pampero is a well-documented cold, dry wind that affects Argentina and Uruguay, particularly during the winter months. It blows from the southwest and often brings rapid temperature drops and clear, cold conditions. This is distinct from low pressure areas or moisture-laden winds that bring rainfall.

The Mistral is a famous cold, dry wind that blows through the Rhone Valley in France and out into the Mediterranean. It is specifically known for being cold and dry, making option A correct. Warm winds like the Sirocco or hot dry winds would be classified differently.

The Southern Hemisphere's summer solstice occurs around December 22 when the South Pole is tilted most directly toward the Sun. This is opposite to the Northern Hemisphere, where summer solstice occurs on June 21. The solstices mark the longest and shortest days of the year in each hemisphere.

The Equator experiences minimal seasonal variation because day length and solar angle remain relatively constant year-round. Seasons become increasingly pronounced toward the poles, where day length and solar insolation vary dramatically. The Arctic Circle has extreme seasonal differences, 45°N has significant variation, and the Tropic of Cancer has moderate seasonal changes.

An avalanche (also called a snow slide or snow slip) is a rapid flow of snow down a sloping surface. Avalanches are typically triggered in a starting zone from a mechanical failure in the snowpack (slab avalanche) when the forces on the snow exceed its strength but sometimes only with gradually widening (loose snow avalanche).

A tornado is a type of storm. Rain is a type of precipitation. 

'Frequently' means often or at short intervals. So, it makes sense here according to the context of the sentence.

Water expands when it freezes, which exerts pressure on the pipes and causes them to burst.

The equatorial climate (also called tropical rainforest climate) is characterized by consistently high temperatures throughout the year and daily convectional rainfall. This occurs due to intense heating and rising warm moist air that condenses every afternoon, creating heavy but short rainfall events. The Mediterranean climate has wet winters/dry summers, continental climates have extreme seasonal variations, and temperate climates are more moderate than the consistently hot equatorial regions.

Isohels are lines on a map connecting points that receive equal duration of sunshine or mean daily sunshine hours. They are analogous to isotherms (temperature), isobars (pressure), and isohyets (rainfall).

Cotton plant is grown in black soil at places with warm climate.

Blizzards are severe snowstorms characterized by strong winds and low visibility. They are most common in polar and Antarctic regions due to extreme cold temperatures and high wind conditions. Equatorial regions are too hot, while tropical and temperate regions don't experience true blizzards.

Leonid Showers of the 55P/Tempel-Tuttle comet which hurtled towards Earth’s atmosphere were made up mostly of fire molecules.
