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. 0.5 / 0.5 pts Question 1 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 time lapses in the Namib Desert (http://links.asu.edu/111LP_UniqueNamib) . Focus on how the shadows change during the day. Focus on how the stars rotate at night. Question: What aspect of Earth's system causes these shadow changes and star rotation that is discussed in the presentation? Earth's ozone layer Earth's magnetosphere
Earth's 24-hour rotation Correct! Correct! Correct! Correct! Earth's particular gravitty Towards the start of the Earth as a unique system presentation and also in the discussion about the Coriolis Effect, the nature of Earth's rotation in 24 hours was emphasized as being important. Our planet's 24-hour rotation produces the shadow movement and star movement seen in the video (https://www.youtube.com/watch?v=61UMtYTlDJs) . If our planet's rotation was much slower or much faster, the planet would not be as habitable. There would be issues related to storm movement and storm intensity (or lack thereof). 0.5 / 0.5 pts Question 2 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 (http://links.asu.edu/111LP_UniqueSiberiaBoiling) . Question: What aspect of Earth's system is illustrated in this video? Select the best answer. All of the other answers are correct, and hence this is the best answer. Correct! Correct! Correct! Correct! Earth hosts all three phases of water (liquid, gas, solid) The phase change of water from liquid to ice releases 80 calories per gram.
Water in the gas phase can turn directly to solid water and releases 680 calories per gram. 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. 0.5 / 0.5 pts Question 3 In the GPH 111 lecture, Earth as a Unique System, you learned about many different aspects of the planet that are unique in our solar system. Please watch (or even skim) this video of stormscapes (http://links.asu.edu/111LP_UniqueStormscapes) -- focusing on the clouds. Question: What unique aspect of Earth's system is displyed in this stunning video? Earth's liquid water Correct! Correct! Correct! Correct! Earth's ozone layer Earth's particular gravitty Earth's magnetosphere

Towards the start of the Earth as a unique system presentation, the nature of Earth's liquid water was emphasized. While other bodies in the solar system contain solid water, the fact that Earth is dominated by liquid water (clouds, oceans, lakes, rivers, groundwater) is a critical aspect of our planet's habitability. Liquid water facilitates the biochemical reactions that allow life. 0.5 / 0.5 pts Question 4 In the GPH 111 lecture, Earth as a Unique System, you learned about many different aspects of the planet that are unique in our solar system. Please watch (or even skim) this ultra-high definition video (http://links.asu.edu/111LP_UniqueAuroraISS) of Aurora (northern and southern lights) as seen from the International Space Station. QUESTION: What aspect of Earth uniqueness generates the Aurora (northern or southern lights) effect? Earth's ozone layer in the troposphere Earth's ozone layer in the stratosphere Earth's particular gravitty Earth's magnetosphere Correct! Correct! Correct! Correct!
Towards the middle of the Earth as a unique system presentation, the magnetosphere was emphasized as a key reason for our planet's habitability. The magnetosphere protects Earth from incoming solar radiation. In the case of the auroras (northern and southern lights), highly charged particles emitted from the sun (typically by solar flares) are able to make it through the magnetosphere at the poles. These charged particles then collide with the upper atmosphere and these collisions result in light bursts or photons. Quiz Score: 2 out of 2
