Question 1
0.5 / 0.5 pts
This lab practical require that you have watched the GPH 111 lecture on Earth as a Unique System (see
link with all the rest of the lecture). You will be asked to watch a video that relates to different aspects of
Earth's uniqueness that are discussed in the lecture. You will be given some background and then you
will have to answer a multiple-choice question linking the video to some aspect of Earth's uniqueness as
a planetary system.
In the GPH 111 lecture, Earth as a Unique System, you learned about many different aspects of the
planet Earth. Please watch (or even skim) this video of what happens to boiling water when it is
thrown off a balcony in Siberia in winter

Water in the gas phase can turn directly to solid water and releases 680 calories per gram.
Correct!
All of the other answers are correct, and hence this is the best answer.
The phase change of water from liquid to ice releases 80 calories per gram.
Earth hosts all three phases of water (liquid, gas, solid)
This video of boiling water thrown off a balconey in Siberia in winter
(https://www.youtube.com/watch?v=jKMNSvpB9dY) shows that the planet Earth hosts water as a gas, as
a liquid (that is boiling), and then as a solid. The solid ice involves two types of phase changes. The
liquid water changes to ice, and also the gaseous water changes to ice. When there is a phase change
to ice -- this requires energy. The slide in the lecture indicates that 80 cal/g are released when water
freezes and 680 calories are released when gas turns to a solid.
Question 2
0.5 / 0.5 pts
Earth's ozone layer in the stratosphere explains the faint sun hypothesis.
Earth's magnetosphere explains the faint sun hypothesis.
Correct!
Rock decay on Earth led to the absorption of carbon dioxide in the products of rock weathering. Put another way,
limestone and dolomite rocks contain carbonate. Calcium carbonate (CaCO3) and magnesium carbonate (MgCO3)
thus store carbon dioxide. Over very long periods of time, the slow decrease in carbon dioxide could have kept the
Earth from overheating as the sun gradually increased its output.
Earth's ozone layer in the ionosphere explains the faint sun hypothesis
Question: What aspect of Earth's system is illustrated in this video? Select the best answer.
In the GPH 111 lecture, Earth as a Unique System, you learned about many different aspects of the
planet Earth - including how Earth maintained its temperature favorable for life throughout its history.
