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 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.

Correct! Correct! Water in the gas phase can turn directly to solid water and releases 680 calories per gram. 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. 0 / 0.5 pts Question 2 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 particular gravitty

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. 0 / 0.5 pts Question 3 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 (http://links.asu.edu/111LP_UniqueLayer) about one special aspect of our planet's system. Question: What aspect of Earth's system is illustrated in this video? Select the best answer. Earth's magnetosphere ou Answered ou Answered Earth's ozone layer in the ionosphere Earth's ozone layer in the stratosphere orrect Answer orrect Answer Earth's ozone layer in the troposphere

The discussion of Earth's ozone layer in the stratosphere is towards the end of the lecture, and it is also explained in the video. 0.5 / 0.5 pts Question 4 The topic of drifts in the rotational axis of Earth is one of many topics that just cannot be squeezed into the GPH 111 Earth as a Unique System lecture. There's just so much special about Earth. There's a pool of questions where students are given questions randomly ... and you have lucked out. You get to read a bit about very recent changes in the rotational axis of Earth. There's a popular story written up nicely by a journalist (https://canvas.asu.edu/courses/172892/files/77690546?wrap=1) , and there's a nerdy research article written up poorly by scientist (https://canvas.asu.edu/courses/172892/files/77690549?wrap=1) . Pick one and give the best answer to this question. Why has the rotational axis of the Earth changed in the last few decades? there have been no recent changes to Earth's axis of rotation; it is all just disinformation from scientists changes in the location of humans moving to urban centers changes to plate tectonic major earthquakes changes in the location of water on Earth Correct! Correct!

However, at the most basic level, the location of water has changed due to glacial melting, and its very possible that this has been due to human activities. Please do not lose any sleep at night over this! Quiz Score: 1 out of 2
