Describe three major causes or climate change 80) Define "climate." Answer: Weather, especially temperature and precipitation, averaged over a period of years. 81) Indicate the approximate date or dates at which the noonday sun is seen directly overhead at the following latitudes: 23.5°S ___________________________ 0° ___________________________ 23.5°N ___________________________ Answer: Dec. 21; Mar 21 and Sept. 22; June 21. 82) Describe the greenhouse effect in terms of radiant energy exchanges. Answer: Shortwave energy from the sun passes through the atmosphere, is absorbed by Earth's surface, and is re-radiated as longwave energy, which is absorbed by the atmosphere, thus warming it. 83) On an average annual basis the tropics receive more radiation from the sun than they send back as longwave radiation, and high-latitude areas send out more longwave radiation than they receive as shortwave radiation from the sun. How is this possible? Answer: Excess heat absorbed in the tropics is advected in the atmosphere and ocean currents to high latitudes where it is radiated to space. 84) Why do hurricanes develop mostly over ocean areas, and usually in late summer and early autumn? Answer: They develop over ocean areas because they depend on latent heat as a major source of energy; latent heat is most plentiful in late summer and early autumn when the ocean is warmest. 85) Explain how precipitation is usually measured. Answer: It is usually measured by collecting rain or snow in a cylindrical container that is marked in millimeters or hundredths of an inch. Snowfall is normally recorded as the amount of liquid water. 86) In climate classification and mapping, what is the advantage of defining climate types based on vegetation? Answer: Vegetation is influenced by climate, so differences in vegetation can be used as indicators of climate type where weather data are lacking. Global Sci LO: 7. Demonstrate the ability to make connections across Geography. 87) D climates occur exclusively in the ________ Hemisphere. Answer: Northern Topic/Section: Earth's Climate Regions Learning Outcome: 12. Describe the major climate types 88) Consider a Mediterranean climate in the Northern Hemisphere. In what months does the rainy season occur? Why does rainfall occur mostly at this time of year and not at other times? Answer: The rainy season is in the winter (December-February) because during this season the mid-latitude low dominates, while in the summer the subtropical high dominates this climate. Topic/Section: Earth's Climate Regions Learning Outcome: 12. Describe the major climate types 89) During what months of the year does the rainy season occur in a seasonally humid tropical climate in the Southern Hemisphere? Answer: During the high-sun period: December-February. Topic/Section: Earth's Climate Regions Learning Outcome: 12. Describe the major climate types 90) In the Köppen climate classification, humid climates are grouped according to temperature, but dry climates are identified by a combination of temperature and precipitation information. Why are both types of data needed to identify dry climates? Answer: Because dry climates are defined in terms of the amount of moisture needed to support vegetation, which is higher in warm climates than in cool climates. Topic/Section: Earth's Climate Regions Learning Outcome: 12. Describe the major climate types 91) What causes the precipitation shifts of seasonally humid tropical climates? Answer: When the ITCZ moves from one hemisphere to the next it brings maximum precipitation with it. Topic/Section: Earth's Climate Regions 92) Identify two different geologic processes that may cause climatic change. Answer: Plate tectonics changes the distribution of land and water, influencing circulation. Volcanic eruptions eject dust and sulfur oxides into the atmosphere, causing temporary cooling. Change Learning Outcome: 13. Describe three major causes or climate change 93) Discuss the role of latent heat exchange in energy movements at the global scale. Answer: Latent heat exchange is when water changes state and is a key component of the precipitation process and involves the transfer of tremendous energy from low latitudes to high latitudes causing the development of major weather systems and hurricanes. 94) Describe the mechanisms that cause precipitation. Answer: The mechanisms that cause precipitation are condensation, the conversion of water vapor to a liquid state, and rising air through convection, orographic uplift or frontal uplift. Global Sci LO: 1. Demonstrate an understanding of the principals of scientific inquiry. 95) Describe the weather you would experience with the passage of a mid-latitude cyclone. Answer: During a mid-latitude cyclone you would encounter significant changes in temperature and precipitation and would experience shifting winds. 96) Describe the five major categories of the Köppen Climate Classification. Answer: Climate A - Tropical, climates that are warm all year; Climate B - Dry Climates; Climate C - Midlatitude Climates with warm summers and cool winters; Climate D - Midlatitude Climates with warm summers and cold winters; Climate E - Polar Climates 97) What two weather conditions contribute to climate classifications? What role does vegetation play in classifying climates? Answer: The two summary weather conditions that contribute to climate classification are precipitation and temperature. Precipitation helps to determine wet or dry climates where temperature is used to determine hot or cold climates. Vegetation was used by Köppen to provide more meaning to climate classifications than arbitrary temperature and precipitation levels. Learning Outcome: 12. Describe the major climate types 98) Explain global warming, its causes, and its consequences. Answer: Global warming is the result of the Earth's temperature increasing during the 20th century by approximately 1 degree Celsius. This increase in global temperature is due to increases in greenhouse gases such as CO2 that enhance the greenhouse effect. The effects of global warming are a reduction in the size of glaciers and the polar ice sheets and consequently a rise in sea level. Change Learning Outcome: 13. Describe three major causes or climate change
