[Mission 2024] STATIC QUIZ, 13 December 2023 – Geography

Solution: c)

The term demographic trap is used by demographers “to describe the combination of high fertility (birth rates) and declining mortality (death rates) in developing countries, resulting in a period of high population growth rate (PGR).”

Solution: c)

Smog is basically derived from the merging of two words; smoke and fog. Smog is also used to describe the type of fog which has smoke or soot in it. Smog is a yellowish or blackish fog formed mainly by a mixture of pollutants in the atmosphere which consists of fine particles and ground-level ozone. Smog which occurs mainly because of air pollution can also be defined as a mixture of various gases with dust and water vapor.

Solution: b)

Statement 2 is incorrect.

While picking names for cyclones, countries need to follow some rules. If those guidelines are followed, the name is accepted by the panel on tropical cyclones (PTC) that finalises the selection. The guidelines are:

* The proposed name should be neutral to (a) politics and political figures (b) religious believes, (c) cultures and (d) gender

* Name should be chosen in such a way that it does not hurt the sentiments of any group of population over the globe

* It should not be very rude and cruel in nature

* It should be short, easy to pronounce and should not be offensive to any member

* The maximum length of the name will be eight letters

* The proposed name should be provided with its pronunciation and voice over

* The names of tropical cyclones over the north Indian Ocean will not be repeated. Once used, it will cease to be used again. Thus, the name should be new.

Some of the names picked by India were suggested by the general public. An IMD committee is formed to finalise the names before sending it to the PTC.

Solution: b)

Statement 2 is incorrect.

Temperatures must be above the historical average in an area for two or more days before the label “heat wave” is applied to a hot spell. But the definition can vary by region;

Heat waves begin when high pressure in the atmosphere moves in and pushes warm air toward the ground. That air warms up further as it is compressed, and we begin to feel a lot hotter.

The high-pressure system pressing down on the ground expands vertically, forcing other weather systems to change course. It even minimizes wind and cloud cover, making the air more stifling. This is also why a heat wave parks itself over an area for several days or longer.

Solution: b)

Statement 2 is incorrect.

The wet bulb temperature is usually lower than the dry bulb temperature, and the difference between the two increases dramatically as the air becomes dry.

The most worrying weather measurement is not the heat typically reported in forecasts but the wet-bulb temperature, which combines heat and humidity to indicate how much evaporation can be absorbed into the air. At wet-bulb temperatures above 35 degrees Celsius, we become unable to reduce our temperature via sweating and will suffer potentially fatal heatstroke after only a few hours, even with shade and water.
