SC.6.E.7.3 – Air Temperature El Niño is a weather pattern in which the normally cool ocean currents of the tropical Pacific Ocean become warmer. How does this most likely affect weather along the West Coast of the United States? A. It does not affect weather in West Coast states. B. It makes summers colder C. It makes winters warmer D. It makes storms more predictable 1

SC.6.E.7.3 – Air Pressure An area of high pressure will most likely result in which type of weather? A. Snowy weather B. Stormy weather C. Cloudy weather D. Clear weather 2

SC.6.E.7.3 – Bodies of Water Cities along the coast tend to have warmer winters than inland cities. Which is most responsible for the moderate climate of coastal cities? A. The ocean cools more slowly than land. B. The water reflects more of the Sun’s light than the land. C. The dry coastal air cannot hold as much heat as inland air. D. Winds from the ocean push cold weather away from the coast. 3

SC.6.E.7.3 Predicting Weather 1. C 2. D 3. A Overall Summary: Both global and local patterns can influence the weather. Some factors include temperature, air pressure, wind direction and speed, humidity, and precipitation. Generally weather is a consequence of the movement of warm and cool air through convections currents. Hot air rises creating a low pressure area and cool air sinks creating a high pressure area. Discussion?

SC.6.E.7.6 – Weather and Climate Sally is looking out her window and sees a lot of thick dark grey clouds moving towards her. She realized that almost every day during the summer this happens around 3 o’clock in the afternoon. Which of the following best describes the phenomenon sally is observing? A. Climate because it covers the entire sky. B. Weather because it is only true for her area. C. Weather because it happens at the same time. D. Climate because it happens every day during the summer. 4

SC.6.E.7.6 – Properties of a Climate The western United States contains some desert climate areas just east of the Sierra-Nevada Mountains. These places, on average, receive very little rain throughout the year and the air is almost completely dry. Which of the following best explain why this is a description of a climate? A. It is based on long-term, averaged, observations. B. It is based on short-term, day-to-day, observations. C. It is based on the humidity of the air at specific times and dates. D. It is based on observations from the people who live in that area. 5

SC.6.E.7.6 – Weather and Climate Which of the following best describes the difference between weather and climate? A. Climate is short term and over a large area. Weather is long term and local. B. Climate is long term and over a large area. Weather is short term and local. C. Climate is long term and local. Weather is short term and over a large area. D. Climate is short term and local. Weather is long term and over a large area. 6

SC.6.E.7.6 Weather and Climate 4. B 5. A 6. B Overall Summary: Weather is short-term and happens over a relatively small area. The climate of an area is based on data such as daily weather, humidity, precipitation, air temperature, etc; it is averaged over a long period of time. Discussion?

SC.6.E.7.4 – Interactions among Earth’s Systems The sun evaporates ocean water which eventually turns into clouds. The clouds move over land and release the water as rain. The rain finally moves down rivers and streams back into the ocean. Which of the following interactions is NOT listed above? A. Hydrosphere to Atmosphere B. Geosphere to Hydrosphere C. Atmosphere to Geosphere D. Biosphere to Geosphere 7

SC.6.E.7.4 – Interactions among Earth’s Systems The interaction between the cryosphere and the hydrosphere have the ability to dramatically change our global climate. Which of the following events shows an interaction between the cryosphere and the hydrosphere. A. A large iceberg melting in the ocean. B. Evaporated water condensing to form clouds. C. Trees releasing oxygen into the environment. D. The Himalayan Mountains being pushed upward. 8

SC.6.E.7.4 – Interactions among Earth’s Systems Trees take in water, carbon dioxide, and nutrients in order to live and reproduce. Their roots help to hold soil in place and slow down erosion while their leaves can stop direct sunlight from reaching the ground. Of all these functions and uses, which shows an interaction between the geosphere and the biosphere? A. roots slowing down erosion B. leaves stopping direct sunlight C. trees taking in nutrients from water D. carbon dioxide being absorbed from the air 9

SC.6.E.7.4 Interactions among Earth’s Systems 7. D 8. A 9. A Overall Summary: All of Earth’s systems interact in some fashion. The hydrosphere includes all of the bodies of water on the surface. The geosphere is the land. The cryosphere is mainly at the poles. The biosphere includes areas where life exists. The atmosphere covers all the others. Discussion?

SC.6.E.7.9 – Atmosphere and Life Ozone is a pale blue gas at standard conditions. Ozone is one of the most toxic inorganic substances known, causing flexible materials, such as lung tissue, to become extremely brittle. Even though it is dangerous at ground level, ozone is important to life on Earth. Why is ozone important to life on Earth? A. Ozone made in laboratories cools refrigerators and air conditioners. B. Ozone in the troposphere destroys excess atmospheric carbon dioxide. C. Ozone in the atmosphere absorbs harmful ultraviolet radiation. D. Ozone in the atmosphere absorbs energy that is reradiated by Earth. 10

SC.6.E.7.9 – Atmosphere Composition Which layer of the atmosphere contains most of the weather and water vapor? A. stratosphere B. troposphere C. mesosphere D. ionosphere 11

SC.6.E.7.9 – Layers of the Atmosphere Which characteristic best defines one layer of the atmosphere from another? A. density B. composition C. temperature D. convection currents 12

SC.6.E.7.9 Properties of the Atmosphere 10. C 11. B 12. C Overall Summary: The atmosphere is a mixture of gases that surround Earth and protects life from harmful ultraviolet rays through the ozone layer. All other layers of the atmosphere are separated by temperature rather then density or composition. Generally the temperature decreases as altitude increases in the troposphere. All weather and water vapor are found in the troposphere. Discussion?
