U3M3L2: Atmospheric and Oceanic Circulation

Wind is used as a _______________ source of energy. renewable. Wind is the movement of air from areas of _____ pressure to areas of _____ pressure. high; low. Cool air over the land moving towards lower pressure over the water at night is called ___________. land breeze. Cool air over the ocean moving towards lower pressure over the land during the day is called ___________. sea breeze. The only way that a sea breeze could occur at night is if the land stayed ________ than the water. warmer. Sun's energy warms Earth unevenly. These differences in temperature create differences in air pressure creating ________ and _________. global winds. Warm air rises and flows north and south, away from _____________. the equator. Cold air sinks and flows north and south, away from _____________. the poles. The transfer of thermal energy by the movement of particles within matter is called ____________. convection. Cold winds that blow from east to west near the North and South Pole are called___________. polar easterlies. Steady winds that flow from west to east between 30 degrees north and 60 degrees north and 30 degrees south and 60 degrees south are called___________.HINT: These winds blow across the US. prevailing westerlies. Steady winds that flow from east to west between 30 degrees north and south latitude are called___________. trade winds. The Coriolis effect causes moving air and water to appear to curve to the _______ in the Northern Hemisphere and to the ______ in the Southern Hemisphere. right; left. Which of these choices is densest and would sink to the bottom? Cold, salt water. Which of these choices is least dense and would float to the top? Warm, fresh water

Chapter Two - Atmospheric & Oceanic Circulation

What do the arrows on the image of Earth indicate: Coriolis effect. What causes the movement of wind and water to the right or left on Earth: Earth's rotation. Which does NOT affect the direction of currents: water depth. What happens when cold, salty water sinks: Density currents are produced. Where do the densest ocean currents usually form: in polar regions. What type of vertical circulation current brings deep, cold water to the ocean surface: upwelling. Look at the image. What is the name of the nighttime circulation shown: land breeze. What is the primary cause of global wind patterns on Earth: uneven heating of Earth's surface. Which is a narrow band of high winds located near the top of the troposphere: jet stream. In the picture,trade winds in the northern hemisphere are located between which latitudes: between 0° and 30°. The amount of energy an area receives depends largely on: the Sun's angle. How does thermal energy move between objects: . Which gas is NOT an efficient greenhouse gas: helium. How is energy transferred when objects are in contact: conduction. In the image,what type of heat transfer is represented by number 2: convection. In what form does most solar radiation reach Earth: visible light. Which statement best explains why different areas of the Earth have different amounts of heat energy: The Earth receives different amounts of solar energy in different regions.. What causes wind: air flowing from a high pressure area to a low pressure area. Heat from the surface is transferred underground by which process: conduction. The method of heat transfer that plays a central role in transferring heat energy within the atmosphere and the ocean is: convection. Convection currents, resulting from uneven heating of the Earth's surface, cause _______ to form: wind. The atmosphere flows in large convection currents. What happens during atmospheric convection: Warm air rises, and cool air sinks.. During the day, when the Sun is shining, the ground gets warm mainly as a result of..: radiated heat from the Sun being absorbed by the ground.. The trade winds are winds that blow toward the Equator. Which of these is the main cause of the trade winds: differences in air pressure. At night in coastal regions, land breezes often develop. Which of these best explains why they develop: The land cools down more quickly than the ocean.
