- Diurnal temperature ranges are minimal in sandy deserts.
- Clear skies and low humidity lead to low diurnal temperature ranges.
- Temperatures can exceed 50°C in some desert locations.
- Mean annual temperatures in hot deserts are typically below 20°C.
How does fog contribute to vegetation in coastal desert areas?
- Fog provides direct rainfall that supports plant life.
- Moisture from fog drip is adequate for supporting vegetation on coastal hills.
- Fog reduces soil temperature, promoting plant growth.
- Fog increases soil salinity, which benefits certain desert plants.
What is a common climatic phenomenon observed in the coastal regions of deserts like the Atacama and Kalahari?
- Frequent thunderstorms are a regular occurrence.
- Heavy snowfall is common during winter months.
- Mists and fog are frequently observed.
- High levels of rainfall are typical.
Which statement best describes the precipitation patterns in the Atacama Desert?
- The Atacama Desert receives regular and significant rainfall throughout the year.
- Some weather stations in the Atacama Desert have never recorded any rainfall.
- Rainfall is common in the Atacama Desert, especially during the summer months.
- The Atacama Desert experiences high levels of precipitation due to its proximity to the ocean.
Identify the correct statements regarding the climatic conditions in desert environments.
- Extremely high temperatures, exceeding 50°C, have been recorded in specific desert locations like Death Valley.
- Low diurnal and annual temperature ranges are a common feature of desert climates.

Which of the following factors contributes to the formation of deserts?
- Descending air in subtropical high-pressure belts.
- The leeward side of mountain ranges (rain shadow effect).
- Inland location away from oceanic moisture sources.
- The presence of warm ocean currents offshore.
Identify the primary atmospheric circulation pattern associated with the location of large hot deserts.
- The Hadley Cell dominates atmospheric circulation in tropical areas.
- Large hot deserts are typically found under the descending limb of the Hadley Cell.
- The ascending limb of the Hadley Cell, which brings rainfall, is characteristic of desert regions.
- The Ferrel Cell is the primary driver of desert formation in tropical latitudes.
റീഡിങ് ലെൻസിലൂടെ സൂര്യപ്രകാശം പേപ്പറിൽ പതിപ്പിച്ചാൽ ഉണ്ടാകുന്ന മാറ്റങ്ങളാണ് ചുവടെ നൽകിയിരിക്കുന്നത്. ഇതുമായി ബന്ധപ്പെട്ട ശരിയായ പ്രസ്താവനകൾ തിരഞ്ഞെടുക്കുക?
- പേപ്പറിൽ നിന്ന് ഒരു പ്രത്യേക അകലത്തിൽ ലെൻസ് പിടിക്കുമ്പോൾ, പ്രകാശഖണ്ഡത്തിന്റെ വലുപ്പം കുറയുന്നു.
- പേപ്പറിൽ നിന്ന് ഒരു പ്രത്യേക അകലത്തിൽ ലെൻസ് പിടിക്കുമ്പോൾ, പ്രകാശഖണ്ഡത്തിന്റെ വലിപ്പം കൂടുന്നു.
- ആ ഭാഗത്ത് പ്രകാശതീവ്രത കൂടുതലായിരിക്കും.
- അതേ അകലത്തിൽ ലെൻസ് കൂടുതൽ നേരം പിടിച്ചാൽ, കടലാസ് പുകയുകയും, തീ കത്തുകയും ചെയ്യുന്നു.
What role do cold ocean currents play in desert formation?
- Cold ocean currents cool the air above them, leading to suppression of rainfall.
- The Benguela Current is associated with the formation of the Kalahari Desert.
- The Humboldt Current contributes to the arid conditions of the Atacama Desert.
- Cold ocean currents increase humidity and promote heavy rainfall along coastlines.
How does the interior location of continents influence desert formation?
- Being far from oceans, continental interiors receive less moisture from maritime air masses.
- The Gobi Desert's formation is partly attributed to its inland location.
- Interior continental locations always guarantee lush vegetation due to the absence of coastal influences.
- Moisture from oceans can easily penetrate deep into the interior of large continents to sustain rainfall.
What is the 'rain shadow effect' and how does it contribute to desert formation?
- The rain shadow effect occurs when mountains block moisture-laden winds from reaching the leeward side.
- As winds rise over mountains, they cool and release precipitation on the windward side, leaving the leeward side dry.
- The Sonoran Desert in North America is an example of a desert formed primarily by the rain shadow effect.
- The rain shadow effect is caused by cold ocean currents.
Which of the following statements correctly describes the formation of hot deserts?
- Large hot deserts like the Sahara and Arabian deserts are found in the trade wind belt near sub-tropical high-pressure belts.
- These deserts are located under the ascending limb of the Hadley Cell, leading to increased condensation and precipitation.
- The descending limb of the Hadley Cell, which causes air to warm adiabatically and inhibits precipitation, is a key factor in their formation.
- Hot deserts are primarily formed due to extreme volcanic activity.
