Select all the factors below that contribute to Earth's ability to support liquid water. correct
answerDistance 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 answerAtmospheric Composition
Maximum Albedo correct answer0.76
Minimum Albedo correct answer0.1
Temperature of Earth (degrees C) correct answer-19.1
Temperature of Earth (degrees C) correct answer2.7
While we can calculate the temperature of an asphalt-covered Earth, is this realistic? correct answerNo,
it's not feasible to pave the oceans because asphalt is heavy and would sink.
Temperature of Earth (degrees C) correct answer-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 answerYes, 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 answerMake a hypothesis
The aerosol increased albedo, increasing Earth's temperature
Temperature of Earth after eruption (degrees C) correct answer-19.8
Degrees colder (C) correct answer1.6
Was your hypothesis supported by the data? correct answerNo it was not supported
What trends did you notice about snow and ice in Then and Now? correct answerLevels 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
answerIncreasing temperature
What will happen to Earth's albedo from the loss of snow and ice? correct answerEarth's albedo will
decrease
If all else is constant, what should the change in Earth's albedo mean for the global average
temperature? correct answerThe global average temperature will increase
You've now investigated several scenarios regarding Earth's albedo. Is it likely, then, that a change in
Earth's albedo is causing the temperature increase? correct answerNo. Earth's albedo is decreasing
because snow and ice are melting, but it is the temperature increase causing the melt, not the other way
around.
Perihelion Temperature (degrees C) correct answer-15.6
Aphelion Temperature (degrees C) correct answer-20.7
