What is the approximate temperature in the subtropical continental region of Asia along 30°N latitude in July? A. 20°C B. More than 30°C C. 10°C D. Less than 10°C Explanation: The subtropical continental region of Asia along 30°N latitude experiences hot temperatures in July, exceeding 30°C. 2 / 202. In which hemisphere is the deviation from the general trend of isotherms more pronounced in January? A. Southern Hemisphere B. Both hemispheres equally C. Northern Hemisphere D. Neither hemisphere Explanation: The deviation of isotherms from the general trend is more pronounced in the Northern Hemisphere in January due to the larger landmass. 3 / 203. What is the term for the incoming solar radiation received by the Earth? A. Terrestrial radiation B. Insolation C. Convection D. Albedo Explanation: Insolation is the term used to describe the incoming solar radiation that reaches the Earth. 4 / 204. What is the process of vertical heating of the atmosphere called? A. Convection B. Advection C. Conduction D. Terrestrial radiation Explanation: Convection is the process of heat transfer through the vertical movement of air currents. 5 / 205. What is the position of the Earth called when it is farthest from the Sun? A. Aphelion B. Perihelion C. Solstice D. Equinox Explanation: The Earth is at its aphelion when it is farthest from the Sun during its orbit. 6 / 206. What is the approximate temperature along 40°S latitude in July? A. 20°C B. More than 30°C C. Less than 10°C D. 10°C Explanation: The temperature along 40°S latitude in July is around 10°C. 7 / 207. In which hemisphere are isotherms more parallel to latitudes, indicating a more gradual temperature variation? A. Neither hemisphere B. Both hemispheres equally C. Southern Hemisphere D. Northern Hemisphere Explanation: The isotherms in the Southern Hemisphere are more parallel to latitudes due to the moderating influence of the larger ocean area. 8 / 208. What is the approximate range of insolation received at the Earth’s surface from the tropics to the poles? A. 0 – 320 Watt/m^2 B. 100 – 300 Watt/m^2 C. 0 – 100 Watt/m^2 D. 50 – 200 Watt/m^2 Explanation: The maximum insolation is received in the tropics (around 320 Watt/m^2) and decreases towards the poles, where it is close to 0 Watt/m^2. 9 / 209. What is the approximate mean monthly temperature for January in the Eurasian continental interior? A. -18°C to -48°C B. 2°C to 10°C C. 10°C to 20°C D. 20°C to 30°C Explanation: The Eurasian continental interior experiences very cold temperatures in January, with the mean monthly temperature ranging from -18°C to -48°C. 10 / 2010. What is the primary reason for the maintenance of a constant temperature on Earth? A. The variation in insolation B. The Earth's albedo C. The process of convection D. The heat budget of the planet Explanation: The Earth maintains a constant temperature because the amount of heat received from the Sun is balanced by the amount of heat radiated back into space. 11 / 2011. What is the term for lines joining places having equal temperature? A. Contours B. Isobars C. Isotherms D. Albedo lines Explanation: Isotherms are lines on a map that connect points with the same temperature. 12 / 2012. Which of the following factors has the LEAST influence on the variation in insolation? A. Length of the day B. Rotation of the Earth C. Angle of inclination of the Sun's rays D. Configuration of land Explanation: While the configuration of land does have some influence on insolation, it is less significant compared to the other factors listed. 13 / 2013. What is the primary reason for the higher temperature in the Northern Atlantic Ocean in January? A. Latitude B. Warm ocean currents C. Continentality D. Altitude Explanation: The presence of warm ocean currents like the Gulf Stream and North Atlantic Drift contributes to the warmer temperatures in the Northern Atlantic Ocean in January. 14 / 2014. What is the highest range of temperature observed on Earth? A. More than 60°C B. 40°C C. Less than 10°C D. 30°C Explanation: The highest range of temperature is found in the north-eastern part of the Eurasian continent, exceeding 60°C. 15 / 2015. What process adds color to the sky? A. Convection B. Advection C. Scattering D. Conduction Explanation: The scattering of sunlight by small particles in the atmosphere is responsible for the blue color of the sky and the red color of sunsets. 16 / 2016. Which regions on Earth have a surplus of net radiation balance? A. The tropics B. The poles C. The mid-latitudes D. The subtropics Explanation: The regions between 40 degrees north and south latitudes have a surplus of net radiation balance. 17 / 2017. How does the atmosphere primarily get heated? A. Directly by short wave solar radiation B. By reflection of solar radiation C. By long wave terrestrial radiation D. By absorption of short wave solar radiation Explanation: The atmosphere is primarily heated indirectly by the long wave radiation emitted by the Earth after it has been heated by insolation. 18 / 2018. What percentage of incoming solar radiation is absorbed by the Earth’s surface? A. 51% B. 35% C. 65% D. 14% Explanation: Out of the 100% of incoming solar radiation, approximately 51% is absorbed by the Earth’s surface. 19 / 2019. What is the term for the amount of solar radiation reflected back to space by the Earth? A. Albedo B. Terrestrial radiation C. Heat budget D. Insolation Explanation: Albedo is the fraction of solar radiation that is reflected back into space by the Earth. 20 / 2020. Where is the least range of temperature found on Earth? A. Between 80°N and 80°S B. Between 20°N and 15°S C. Between 40°N and 40°S D. Between 60°N and 60°S Explanation: The least range of temperature, approximately 3°C, is found between 20°N and 15°S latitudes.
