During which step in the Can Crush Lab did water vapor force air from the can? The can was filled nearly to the top with water. The can was placed on the hot stove top burner for several minutes. The can was removed from the hot stove top burner. The can was placed upside-down in the water-filled pan. --------------------------------------… Question 2 (Multiple Choice Worth 2 points)As a barometer rises, what kind of weather can be expected? There will likely be no change in the weather. The weather will likely become clearer and drier. The weather will likely become cloudier and stormier. The weather will likely become warmer and more humid. --------------------------------------… Question 3 (Multiple Choice Worth 2 points)Water molecules evaporate from a lake near the equator and rise into the atmosphere, as shown in the diagram below. As the molecules travel away from the equator, which step in the water cycle is most likely to happen next? The molecules cool and eventually form clouds. The molecules freeze and eventually form ice crystals. The molecules heat up and eventually form water vapor. The molecules break apart and eventually form precipitation. --------------------------------------… Question 4 (Multiple Choice Worth 2 points)Which of the following correctly describes a way in which Earth’s atmosphere interacts with the geosphere? It contains gases that living organisms breathe. It contains gases that trap incoming solar radiation. It provides a medium for cycles that provide nutrients to living organisms. It provides a medium for water to move between Earth’s surface and the air. --------------------------------------… Question 5 (Multiple Choice Worth 2 points)What is the relationship between temperature and altitude in the troposphere? As altitude increases, temperature decreases. As altitude increases, temperature increases. As altitude increases, temperatures remain the same. As altitude increases, temperatures vary. --------------------------------------… Question 6 (Multiple Choice Worth 2 points)What is the relationship between atmospheric pressure and the density of gas particles in an area of increasing pressure? As air pressure in an area increases, the density of the gas particles in that area decreases. As air pressure in an area increases, the density of the gas particles in that area increases. As air pressure in an area increases, the density of the gas particles in that area remains constant. As air pressure in an area increases, the density of the gas particles in that area increases and decreases in an alternating pattern. --------------------------------------… Question 7 (Multiple Choice Worth 2 points)Which of the following is considered a drawback to using wind energy as a source of power? Wind energy is highly polluting. Wind energy is nonrenewable. Winds do not always blow consistently. Winds produce lesser quality energy than other sources. --------------------------------------… Question 8 (Multiple Choice Worth 2 points)Which of the following is not a measurement taken by a radiosonde? atmospheric pressure cloud height humidity temperature --------------------------------------…Question 9 (Essay Worth 5 points)Based on your observations from the Can Crush Lab, explain why a helium balloon that rises into the atmosphere will eventually burst. --------------------------------------…Question 10 (Essay Worth 5 points)Where on Earth’s surface might you be if you are experiencing the westerlies? Explain how air pressure, temperature, and the Coriolis effect influence the movement and direction of these winds.
