Climate, Weather, and Geography

2,194 Questions

Climate, weather, and geography examine temperature variations, wind patterns, atmospheric hazards, and global climate zones. This hub addresses climographs, thunderstorm triggers, and regional climate descriptors. These concepts are essential for UPSC, SSC, and RRB general studies and geography exams.

  1. Cold fronts move at slower rate than warm fronts and therefore cannot overtake the warm fronts.

  2. Cold fronts normally move faster than warm fronts and therefore frequently overtake the warm fronts.

  3. Cold fronts move at slower rate and eventually they are overtaken by the warm fronts.

Which one of the following conditions does not favour the formation of a tropical cyclone?

  1. Temperature above $27°$C

  2. Significant vertical wind difference

  3. High humidity levels

  4. Divergence in the upper atmosphere
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Tropical cyclones require low vertical wind shear to develop. High vertical wind shear disrupts the storm's structure and prevents the vertical alignment necessary for intensification.

Multiple choice physics temperature and heat modes of heat transfer - conduction conduction heat and modes of heat transfer

Sea and land breezes are caused because of :

  1. convection

  2. cyclones

  3. rains

  4. conduction
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

All wind is caused by a pressure gradient. In the case of land or sea breeze, the pressure gradient is due to the different heating and cooling rates of the area.

Lake or sea breeze and land breeze are on a comparatively small scale when viewing meteorological events. This is important to note because large scale heating and small scale heating work differently. In the case of small scale heating, the increase in heat causes an increase in volume which in turn lowers the pressure in that area.
In the morning the land heats up much faster than the water. This eventually results in a pressure gradient with a lower pressure on the land due to the quicker heating. Air moves from the water to the land in the form of a sea breeze.

After sunset, the land cools much quicker than the water. As a result, the volume of the air over the water is higher and the pressure decreases. Ar then moves over the water as a land breeze.

Multiple choice evs interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

Xeric environment is characterised by

  1. Precipitation

  2. Low atmospheric humidity

  3. Extremes of temperature

  4. High rate of vapourisation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Xeric environment means dry conditions or low atmospheric humidity and lack of precipitation. Also the temperature variations depend on several other variables like altitude, latitude and hemisphere. High rates of vapourisation is not a characteristic of environment but a consequence of low atmospheric humidity.

Multiple choice evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

Which one of the following is the region of cold temperature? 

  1. Mesosphere

  2. Thermosphere

  3. Ionosphere

  4. Exosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A. Mesosphere is the layer just above the stratosphere and extends from 50-85 km. Temperature is about -90° C in this region.
B. Thermosphere is the layer above the mesosphere. Ultraviolet radiations can penetrate this layer and causes photodissociation of molecules. Temperature increases in this region.
C. Ionosphere is the region of upper atmosphere of Earth that extends from 60-1000 km. Ionization by solar radiation occurs in this region.
D. Exosphere is the outermost layer of Earth's which hardly contains air.
Hence,the region of cold temperature is Mesophere.
So, the correct answer is 'Mesophere'.
Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

High concentration of greenhouse gases has resulted in maximum rise of atmospheric temperature in 

  1. Tropic region

  2. Middle latitude

  3. Polar region

  4. Temperate region
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Increases in the level of greenhouse gases has led to considerable heating of earth leading to global warming. During the past century, the temperature of earth has increased by $ 0.6  $, most of it during the last three decades. Rise in temperature is slight in tropics, moderate in middle latitudes and maximum in polar regions. It will led to melting of polar ice caps as well as of other places like the Himalayan snow caps.
So, the correct answer is 'Polar region'.
Multiple choice biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

Which of the following is incorrect match?

  1. Polar bear - Eurythermal

  2. Archaebacteria - Hydrothermal vents

  3. Cyanobacteria - Thrive in Antarctic water

  4. Desert lizards - Body temperature fairly constant
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Polar bears are stenothermal because they can tolerate only a narrow range of temperature and are restricted to specific regions only. On the other hand, eurythermal animals can tolerate a wide range of temperature variations and thus have a wider distribution on earth.
  • Archaea are microorganisms that define the limits of life on Earth. They were originally discovered and described in extreme environments, such as hydrothermal vents and terrestrial hot springs. 
  • Cyanobacteria can be found in almost every terrestrial and aquatic habitat—oceans, freshwater, damp soil, temporarily moistened rocks in deserts, bare rock, and soil, and even Antarctic habitats, some of the driest and coldest ecosystems on the Earth.
  • Ectotherms like desert lizards do not use metabolic heat to maintain their body temperature but manage to keep their body temperature fairly constant by behavioural means. They bask in the sun and absorb heat when their body temperature drops below the comfort zone but move in to shade when the ambient temperature starts increasing.
  • So the incorrectly matched option is A.
Multiple choice geography africa - the central continent cocoa cultivation in ghana study of africa africa - location, political divisions and physical features

What type of climate is suitable for the cultivation of cacao trees?

  1. Warm and dry

  2. Warm and wet

  3. Cold

  4. Cold and wet
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Most of the world's cocoa is grown in a narrow belt 10 degrees either side of the Equator because cocoa trees grow well in humid tropical climates with regular rains and a short dry season.

Multiple choice chemistry planet earth acid deposition air and air pollution natural resources- air, water and land

 A thick fog-like layer in the atmosphere, especially during winters it is called:

  1. smoke

  2. smog

  3. dust

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Smog is a thick fog-like layer in the atmosphere, especially during winters, made up of fog and smoke. 


Sulphur dioxide is mainly produced by burning fuels such as coal. It causes respiratory problems, including permanent lung damage.

Hence, the correct option is $\text{B}$
