6th Grade Science Standards 6-4 _______ 1 The picture labeled "Cloud A" shows cirrus clouds. These are often seen in the sky as white, feather-like bands. How are cirrus clouds different than the ones seen in "Cloud B" and "Cloud C" pictures? a. b. c. d. _______ 2 3 Cirrus clouds float very low in the sky. Cirrus clouds do not make rain. Cirrus clouds are darker than other clouds. Cirrus clouds are thicker than other clouds. Cloud C in the pictures above is a stratus cloud. The term "Stratus" is a Latin word that describes the cloud.

These ultraviolet rays are unable to pass through which atmospheric layer? a. b. c. d. _______ 5 The term thermosphere has the root word "therm". Why is this appropriate? a. b. c. d. _______ 6 the Troposphere the Mesosphere the Thermosphere the Stratosphere the air temperature decreases in the Thermosphere the air temperature increases in the Thermosphere the air pressure decreases in the Thermosphere the air pressure increases in the Thermosphere As you move further away from the earth's surface, the pressure of the air decreases. Why is this the case? a. b. the air temperature decreases Earth's pull of gravity decreases c. d. _______ 7 The two most common gases found throughout all of the above layers are: a. b. c. d. _______ 8 9 carbon dioxide and water vapor hydrogen and helium nitrogen and oxygen argon and sulfur dioxide The climate in different regions of the earth is partly determined by convection currents. Which of the following is a general rule that describes the role of convection when it comes to weather? a. b. c. d. _______ the amount of sunlight decreases the amount of gas in the air decreases melting snow turns to water freezing rain turns to snow hot air rises hot water evaporates Areas of the earth are divided into different convection regions based on their what? a. b. c. d. _______ 10 Which of the following terms describes the convection regions closest to the equator (Regions C and D)? a. b. c. d. _______ 11 b. c. d. 12 continental temperate polar tropical The diagram above shows the convection regions of the earth. Which of the following describes how convection current can have an impact on a smaller scale? a. _______ precipitation elevations longitudes latitude convection currents can result in a constant breeze near bodies of water convection currents can influence the direction of ocean currents convection currents help the oceans regulate the temperature on the land convection currents create global wind belts The station model above gives two conflicting readings. What are they? a. b. c. it says that it is snowing, but the temperature is above freezing it says that the sun is shining, but it is an overcast day it says that it is windy, but the wind is not blowing in any d. _______ 13 A sample station model is shown above. Meteorologists use this to determine which of the following? a. b. c. d. _______ 14 15 the average weather conditions over time at a specific observation area the past weather conditions over a given amount of time at a specific observation area the predicted weather conditions for a given amount of time at a specific observation area the current weather conditions at a specific observation area The number 57 on the left of the station model (shown by Letter B) provides information about what? a. b. c. d. _______ direction it says that it is raining, but there are no clouds in the sky wind speed amount of precipitation air pressure temperature Which symbol provides information about the wind speed at the area where the station model is located? a. b. c. d. Letter B Letter C Letter A Letter D _______ 16 Which of the following is shown by the diagram above? a. b. c. d. _______ 17 Letter A is pointing to a fast-moving ribbon of air that is circling the globe. This is knows as a: a. b. c. d. _______ 18 19 heat wave. jet stream. polar wind. gulf stream. The trade winds shown by Letter C are known by which of the following terms? a. b. c. d. _______ wind tunnels seasonal winds wind advisories global winds polar winds easterly winds westerly winds jet streams Prevailing "westerlies" in the temperate region are shown by: a. b. c. d. _______ 20 A meteorologist who is looking at the above map might be concerned that: a. b. c. d. _______ 21 22 the Eastern part of the United States is going to be struck by a hurricane. the Western part of the United States is going to see flooding in certain areas. the Eastern part of the United States is going to suffer from a drought. the Western part of the United States is going to have heavy snow storms. According to the map, the most likely areas of heavy precipitation are: a. b. c. d. _______ Letter B Letter D Letter C Letter A nowhere--there is no precipitation anywhere in the country. across the entire country. in the Eastern United States. in the Western United States. According to the map, which type of weather situation is more likely in the Western part of the United States than in the Eastern part? a. b. c. d. heavy precipitation low visibility high pressure systems low pressure systems _______ 23 Arrow A shows that precipitation is falling from a cloud to the ground. If the air temperature is below zero degrees Celsius in all layers of the atmosphere, the most likely form of this precipitation will be: a. b. c. d. _______ 24 In the water cycle shown above, Arrow B represents "runoff". Where will this running water eventually go? a. b. c. d. _______ 25 freezing rain. hail. snow. sleet. into extremely dry areas into a larger body of water into areas of high elevation it will be absorbed into nonporous materials like pavement and concrete When the water vapor rises into the atmosphere (Arrow C), it starts to cool and transform back into a liquid. The result is the formation of a cloud. The process of water vapor turning into a liquid is known as: a. b. c. filtration evaporation condensation d. _______ 26 Arrow C in the picture above is an example ground water turning into water vapor. If this water vapor had been released by plants, then it would be an example of what? a. b. c. d. _______ 27 28 29 a hollow object that allows air to easily pass through a vibrating object that makes noise as it blows in the wind a metallic object that expands as the temperature rises a flat object that rotates when it pushes against air The psychrometer is used to measure humidity. It does this by recording: a. b. c. d. _______ evaporation transpiration condensation filtration The weather vane shown above is used to monitor wind direction. What is the best definition for "vane"? a. b. c. d. _______ transpiration the changing pressure of the air. the amount of water vapor in the air. the elevation of clouds in the atmosphere. the rate at which water flows through air. A weather vane is only used to show the direction that the wind is blowing.
