What type of radiation does the Earth emit after being heated by the Sun? A. Visible light B. Shortwave radiation C. Ultraviolet radiation D. Longwave radiation Explanation: The Earth emits longwave radiation, also known as infrared radiation, after being heated by the Sun’s shortwave radiation. 2 / 202. What is an ideal condition for temperature inversion? A. Short summer night with cloudy skies B. Long winter night with clear skies and still air C. Short winter day with clear skies and windy conditions D. Long summer day with cloudy skies Explanation: A long winter night with clear skies and still air provides the ideal conditions for temperature inversion to occur. 3 / 203. What is the primary cause of the high annual range of temperature in the Siberian plains? A. Latitude B. Altitude C. Ocean currents D. Continentality Explanation: The Siberian plains experience a high annual range of temperature due to their location deep within the Eurasian continent, far from the moderating influence of oceans. 4 / 204. What does Planck’s law state about the energy radiated by a body? A. Hotter bodies radiate more energy at longer wavelengths. B. Hotter bodies radiate more energy at shorter wavelengths. C. Hotter bodies radiate less energy. D. The energy radiated by a body is independent of its temperature. Explanation: Planck’s law states that the amount and wavelength of radiation emitted by a body are directly related to its temperature. Hotter bodies emit more energy at shorter wavelengths. 5 / 205. What is the primary mechanism by which excess heat from the tropics is redistributed towards the poles? A. Convection B. Advection C. Conduction D. Radiation Explanation: Advection, the horizontal movement of air, plays a crucial role in redistributing heat from the tropics towards the poles, preventing excessive warming in the tropics and cooling in the polar regions. 6 / 206. What is the approximate percentage of incoming solar radiation that is reflected back to space before reaching the Earth’s surface? A. 14% B. 65% C. 35% D. 51% Explanation: Approximately 35% of the incoming solar radiation is reflected back to space by clouds, ice, and other reflective surfaces before it can reach the Earth’s surface. 7 / 207. What is the term for the reversal of the normal lapse rate? A. Advection B. Temperature inversion C. Albedo D. Convection Explanation: Temperature inversion occurs when the temperature increases with altitude instead of decreasing, reversing the normal lapse rate. 8 / 208. What is the primary way in which heat is transferred in the atmosphere? A. Conduction B. Radiation C. Convection D. Advection Explanation: Advection, the horizontal movement of air, is the most significant way in which heat is transferred within the atmosphere. 9 / 209. What is the term for the process by which the Earth-atmosphere system maintains a balance between incoming and outgoing energy? A. Insolation B. Temperature inversion C. Heat budget D. Albedo Explanation: The heat budget refers to the balance between incoming solar radiation and outgoing terrestrial radiation, which helps maintain a relatively stable temperature on Earth. 10 / 2010. What is the term for the rate at which temperature decreases with increasing altitude? A. Specific heat B. Normal lapse rate C. Temperature inversion D. Albedo Explanation: The normal lapse rate is the rate at which temperature decreases with increasing altitude in the troposphere. 11 / 2011. On which date is the Earth closest to the Sun? A. January 3rd B. September 23rd C. July 4th D. March 21st Explanation: The Earth is closest to the Sun on January 3rd, which is referred to as perihelion. 12 / 2012. Over which areas is temperature inversion normal throughout the year? A. Polar areas B. Subtropical regions C. Mid-latitude regions D. Equatorial regions Explanation: Temperature inversion is a common phenomenon in polar regions throughout the year due to the cold temperatures and stable atmospheric conditions. 13 / 2013. What is the term for the flow of cold air down slopes under the influence of gravity? A. Albedo B. Temperature inversion C. Convection D. Air drainage Explanation: Air drainage is the downward flow of cold, dense air along slopes due to gravity, often leading to temperature inversion in valleys and low-lying areas. 14 / 2014. What is the typical temperature profile observed during a temperature inversion? A. Temperature fluctuates randomly with altitude. B. Temperature remains constant with altitude. C. Temperature increases with altitude. D. Temperature decreases with altitude. Explanation: During a temperature inversion, the normal temperature profile is reversed, and temperature increases with altitude instead of decreasing. 15 / 2015. What is specific heat? A. The temperature of a substance. B. The heat required to change the state of a substance. C. The energy needed to raise the temperature of one gram of a substance by one degree Celsius. D. The energy radiated by a substance. Explanation: Specific heat is a measure of the amount of heat required to raise the temperature of a unit mass of a substance by one degree Celsius.16 / 2016. Which atmospheric gases are particularly effective at absorbing longwave radiation? A. Ozone and water vapor B. Nitrogen and oxygen C. Argon and helium D. Carbon dioxide and other greenhouse gases Explanation: Greenhouse gases, primarily carbon dioxide, are efficient at absorbing longwave radiation emitted by the Earth, contributing to the greenhouse effect. 17 / 2017. What phenomenon can surface inversion promote in the lower layers of the atmosphere? A. Instability B. Convection C. Advection D. Stability Explanation: Surface inversion can lead to stable atmospheric conditions in the lower layers, trapping pollutants and contributing to fog formation. 18 / 2018. What is the name of the local wind in India that is a result of the advection process? A. Chinook B. Loo C. Mistral D. Foehn Explanation: The ‘loo’ is a hot, dry wind that blows across the Indo-Gangetic Plain in summer and is caused by advection. 19 / 2019. What is the primary factor that influences the amount of insolation received at different latitudes? A. The Earth's albedo B. The Earth's rotation C. The Earth's tilt on its axis D. Distance from the Sun Explanation: The Earth’s tilt of 66.5 degrees with respect to its orbital plane plays a major role in determining the amount of insolation received at different latitudes. 20 / 2020. Why do slant rays of the Sun result in less energy received per unit area? A. They pass through less atmosphere. B. They cover a smaller area. C. They are less intense. D. They cover a larger area. Explanation: Slant rays spread the same amount of energy over a larger area, resulting in less energy received per unit area compared to vertical rays.
