The amount of energy needed to raise 1 gram of a substance by 1oC is known as ___ Answer: Specific Heat What energy transformations occur to create wind? Answer: Radiant thermal motion (KE) What does a barometer measure Answer: Air Pressure Where on Earth does air have the lowest air pressure and why? Answer: Equator because it is warm there, which means it has a great deal of KE to spread out. Which one has the highest specific heat; landmasses, oceans or the atmosphere? Answer: Oceans (takes longer to change water’s temp.) What does temperature measure? Answer: The amount of movement or kinetic energy of particles in an object. What does an anemometer measure? Answer: Wind Speed Use Diagram A: What is the Temperature, Wind Direction, & Cloud Cover in Bismark, ND T-17o , WD-20 mph NW CC- Total Cloud Cover This form of heat transfer occurs when fluids heat up and rise, then cool down and sink. Answer: Convection Describe 2 things about absolute zero Answer: 1. Zero Kelvin 2. All motion stops 3. No Kinetic Energy 4. –273oC 5. Lowest temperature possible. What is the greenhouse effect? Answer: Earth’s atmosphere traps heat in. Use Diagram D: Where is the hurricane? Answer: point 4 (Cloudy at stations B & C. Wind blowing counterclockwise around it.) This form of heat transfer occurs with light and other types of electromagnetic waves. Answer: Radiation This form of heat transfer moves heat energy through a metal bar. Answer: Conduction What causes the Coriolis effect? Answer: Spin of the Earth Underwater earthquakes, volcanic eruptions, landslides, underwater explosions, or the impact of meteorites can cause these HUGE waves. Answer: Tsunamis This type of front occurs when a warm air mass gets caught between 2 colder air masses Answer: Occluded front Which way does wind always blow? Answer: From high to low pressure What type of front has warm air that rises gradually over cold air and gently pushes cold air away Answer: Warm Front Use Diagram B: What weather conditions can be expected in Dallas TX Answer: Cloudy & Wet with possible storms. (Cold front coming in over Warm air mass – northward is a stationary front) What is the difference between Weather & Climate? Answer: Weather refers to atmospheric conditions at specific time, Climate is weather pattern over long time. What type of weather is associated with Low-pressure systems? What part of the water cycle creates clouds? Answer: condensation How do high-pressure systems form? Answer: Cloudy weather Answer: Cold air sinks Why does southern California remain relatively cool even in the summer? How does humidity compare in warm and cold fronts? Answer: A cool current flows by it keeping the temperature lower. Use Diagram B: What weather conditions can be expected in Helena, Mt? Answer: Clear & Sunny (high pressure) Answer: Warm fronts have more humidity (warmer temp = more KE to cause evaporation.) Use Diagram C: What type of front is represented over Texas? & how are air masses moving? Answer: Cold Front, incoming front is pushing warm air up and over it as it passes thru. What causes land and ocean breezes? Answer: water and land heat up at different rates, so cool high pressure air creates breeze as it blows to warm air What is the difference between a maritime & continental climate & why? Answer: Maritime has more stable temps & rainfall due to ocean. What happens when a cold front meets a humid warm front? Answer: Thunderstorms What direction does the Jet stream flow? Answer: West to East When is hurricane season and why is it then? Answer: June-November because that is when Atlantic Ocean is warmest. What are 2 characteristics of maritime tropical air masses? Answer: Warm and humid What type of pressure system is associated with a hurricane and why? What happens to the weather in South America when there is an El Niño & why? Answer: Low pressure caused by warm air & moisture rising to higher altitudes where it condenses into clouds Answer: Warmer temperatures & more rain due to ocean current flowing eastward instead of westward How does warm temperature affect the water cycle? Where and how do hurricanes form Answer: Warmer temps. Cause greater evaporation & more humidity in the air. Between Dallas & San Diego, which climate is more stable & why? Why does England have such a warm climate if it is so far North? Answer: San Diego because it has a cool ocean current that moderates its temperature Answer: The warm Gulf stream brings and releases heat to England from the equator. What 2 things cause deep currents? Answer: High salinity & low temperature causes denser water. What are 2 ways the ocean’s salinity increases? Answer: Evaporation & Freezing of water Answer: Warm ocean water in the tropics (along equator) rise to produce large storms. What causes most ocean waves? Answer: Wind What is upwelling? Answer: Process in which cold, nutrient rich water from the deep ocean rises to the surface What time of day does a land breeze occur & Why? Answer: Nightime because land will cool faster at night then land, cause high pressure over land pushing into low pressure at sea. Why do hurricanes fall apart? Answer: It moves over land or cold water so it is no longer fed the warm moist air from the tropical ocean. List 3 factors that control surface currents. Answer: Global winds Coriolis effect Continental deflection What is El Nino? Answer: Pacific Ocean Equatorial Currents flow east instead of west due to change in winds.
