What is a large body of air with little horizontal variation in temperature and moisture called? A. Front B. Air mass C. Anticyclone D. Cyclone Explanation: An air mass is a large volume of air with relatively uniform temperature and humidity. 2 / 202. What initiates large and slow-moving currents in the ocean? A. Ocean temperature differences B. Salinity differences C. Earth's rotation D. Large-scale winds of the atmosphere Explanation: The general circulation of the atmosphere, driven by large-scale winds, sets in motion the major ocean currents. 3 / 203. What is the boundary zone between two different air masses called? A. Anticyclone B. Cyclone C. Air mass D. Front Explanation: The transition zone between two distinct air masses is called a front. 4 / 204. What is the wind called that blows from the valley upslope during the day in mountainous regions? A. Valley breeze B. Anabatic wind C. Katabatic wind D. Mountain wind Explanation: In mountainous areas, the valley breeze blows upslope during the day as the slopes heat up and air rises. 5 / 205. What are the winds called that blow from the subtropical high towards the equator? A. Easterlies B. Westerlies C. Geostrophic winds D. Polar easterlies Explanation: The winds blowing from the subtropical high towards the equator are called easterlies. 6 / 206. What is the most pronounced effect of the shifting of pressure and wind belts? A. Monsoons B. Tornadoes C. Local winds D. El Niño Explanation: The shifting of pressure and wind belts causes the most noticeable effect in the monsoon patterns, particularly in Southeast Asia. 7 / 207. What is the pattern of movement of planetary winds called? A. Seasonal winds B. General circulation of the atmosphere C. Local winds D. Ocean currents Explanation: The overall pattern of planetary wind movement is referred to as the general circulation of the atmosphere. 8 / 208. What is the cell in the tropics called in the general circulation model? A. Ferrel Cell B. Hadley Cell C. Convection Cell D. Polar Cell Explanation: The Hadley Cell is the circulation cell in the tropics where air rises at the equator and descends around 30° N and S. 9 / 209. What is a tornado over the sea called? A. Water spout B. Cyclone C. Hurricane D. Typhoon Explanation: When a tornado forms over water, it is referred to as a water spout. 10 / 2010. What is the wind known as when isobars are straight and there is no friction? A. Cyclonic wind B. Geostrophic wind C. Anticyclonic wind D. Trade wind Explanation: When isobars are straight and friction is absent, the pressure gradient force is balanced by the Coriolis force, resulting in wind blowing parallel to the isobars, known as geostrophic wind. 11 / 2011. What type of front is formed when cold air moves towards warm air? A. Cold front B. Occluded front C. Stationary front D. Warm front Explanation: A cold front occurs when a cold air mass advances into a region occupied by warmer air. 12 / 2012. What is the region of calm with subsiding air in the center of a tropical cyclone called? A. Rain band B. Eye C. Eye wall D. Spiral band Explanation: The central point of a tropical cyclone, characterized by calm conditions and low pressure, is known as the eye. 13 / 2013. What type of wind blows from the sea to the land during the day? A. Sea breeze B. Land breeze C. Mountain wind D. Valley breeze Explanation: During the day, land heats up faster than the sea, creating a pressure gradient that causes wind to blow from the sea towards the land, known as sea breeze. 14 / 2014. What is the place called where a tropical cyclone crosses the coast? A. Storm surge B. Eye C. Landfall D. Recurvature Explanation: The point on the coast where a tropical cyclone makes its first landfall is referred to as landfall. 15 / 2015. What is the combined phenomenon of Southern Oscillation and El Niño called? A. ENSO B. Pacific Decadal Oscillation C. North Atlantic Oscillation D. La Niña Explanation: The coupled interaction between the atmosphere and ocean in the tropical Pacific, involving El Niño and the Southern Oscillation, is known as ENSO. 16 / 2016. What is the phenomenon known as El Niño? A. Appearance of warm water off the coast of Peru B. Cooling of the Pacific Ocean C. Heavy rainfall in Australia D. Drought in South America Explanation: El Niño is characterized by the unusual warming of surface waters in the central and eastern tropical Pacific Ocean. 17 / 2017. What generally happens over a low-pressure area? A. Air converges and rises B. No significant air movement C. Air diverges and sinks D. Wind blows parallel to isobars Explanation: In a low-pressure system, air converges towards the center and rises due to lower pressure. 18 / 2018. What is the name of the cell found in the middle latitudes? A. Hadley Cell B. Polar Cell C. Convection Cell D. Ferrel Cell Explanation: The Ferrel Cell is the circulation cell in the middle latitudes characterized by sinking cold air from the poles and rising warm air from the subtropical high. 19 / 2019. What are the winds called that blow from the poles towards the middle latitudes? A. Easterlies B. Polar easterlies C. Geostrophic winds D. Westerlies Explanation: The winds blowing from the poles towards the middle latitudes are called polar easterlies. 20 / 2020. What are weather systems developing in the mid and high latitudes called? A. Monsoons B. Tornadoes C. Extra-tropical cyclones D. Tropical cyclones Explanation: Weather systems forming outside the tropics, in the middle and high latitudes, are known as extra-tropical cyclones.
