BioBeyond Unit 7: Finding the Cause (Test questions with complete answers)

Select all the factors below that contribute to Earth's ability to support liquid water. correct answers Distance from the Sun Atmosphere Albedo (How much light is reflected) As you learned in Our Blue Planet, there is one key factor that this simulation does not take into account. What major factor is missing? correct answers Atmospheric Composition Maximum Albedo correct answers 0.76 Minimum Albedo correct answers 0.1 Temperature of Earth (degrees C) correct answers -19.1 Temperature of Earth (degrees C) correct answers 2.7 While we can calculate the temperature of an asphalt-covered Earth, is this realistic? correct answers No, it's not feasible to pave the oceans because asphalt is heavy and would sink. Temperature of Earth (degrees C) correct answers -99.7 While we can calculate the temperature of a snow-covered Earth, do you think this is realistic? You will be scored on completion, not accuracy. correct answers Yes, shifts in Earth's climate could bring about a snow-covered Earth. Make a hypothesis - what will the eruption of Mt. Pinatubo and the aerosol it releases do to Earth's albedo and temperature? correct answers Make a hypothesis The aerosol increased albedo, increasing Earth's temperature Temperature of Earth after eruption (degrees C) correct answers -19.8 Degrees colder (C) correct answers 1.6 Was your hypothesis supported by the data? correct answers No it was not supported What trends did you notice about snow and ice in Then and Now? correct answers Levels of snow and ice are generally decreasing What is the most likely direct cause of the snow and ice loss you observed in Then and Now? correct answers Increasing temperature
