À propos de cet audio

How the Earth Works takes you on an astonishing journey through time and space. In 48 lectures, you will look at what went into making our planet - from the big bang, to the formation of the solar system, to the subsequent evolution of Earth.

You will travel to the center of our planet and out again, charting the geologic forces that churn beneath our feet to push the continents and seafloor around like froth on the surface of soup. Earthquakes, volcanic eruptions, and tsunamis are byproducts of our planet’s ceaseless activity, and you will focus on specific examples of each to learn why and when they occur. Volcanic activity has produced the atmosphere as a side effect, and you will learn how this sea of air functions at the global scale. Earth’s surface is mostly water, and you will explore the cycling of this vital substance throughout the planet, along with its role in climate, erosion, plate tectonics, and biology.

Not only are humans at the mercy of our planet’s natural forces, but we ourselves have also become agents of change. We are altering the Earth’s land, water, and air faster than any other geologic process. This will be another theme of your journey: how humans have transformed watersheds, leveled mountains, changed the balance of gases in the atmosphere, and caused the extinction of enough species to hasten the end of the 65-million-year-old Cenozoic era. It is vitally important that we understand the nature of our geologic powers if we are to have any hope of controlling them.

very informative

The most amazing class. So much new information that puts life in perspective. Loved it, loved it, loved it. Our Earth is one of a kind and I can't wait to explore it more. The only thing, it's affected my attitude towards religion - in a way that I suddenly find myself much more educated and open minded. It's a change, but a very welcome one. I'll never be able to go back - but neither do I want to. Amazing course. Thank you.

Changed my worldview

I've literally listened to probably over two hundred of the great courses stretching back to when they were the teaching company - This is my first review. This is easily in the top ten. I was in the geology club in high school (nerd alert) so I did not go into this uninformed on the subject, but I can say that after listening to this course I now understand the big picture - how everything works together - and have gained so much insight into what genuinely makes Earth special from this course that I am actually seeing the world differently. This is a 48 lecture course - the longest offered by the Great Courses - and so in depth on such a range of subjects that I cannot recommend it enough. A+

The “lectures” continually refer to props and examples that we can’t see. Oftentimes you can use your imagination but in others it is quite difficult. The professor does a very good job of tying together geology and biology and chemistry to make a coherent story of how the earth was formed and uses many practical examples to make his points. For the most part he keeps it to science and stays away from contention. Quite good.

Not really complete

Un problème est survenu. Veuillez réessayer dans quelques minutes.

This 48-lecture series shows that geology can be enthralling … and that it deals with much more than rocks.

In fact, from the start, the discussion of Earth’s processes integrates many scientific disciplines such as physics, chemistry, biology, meteorology and astronomy.

The lecturer’s enthusiasm is contagious, and his talks are clearly well groomed, with frequent touches of humour. Many listeners will appreciate that as a scientist he unashamedly uses the metric system.

Nothing is perfect, however, and some shortcomings must be pointed out:

• Earth science is a dynamic field so that some information conveyed is clearly outdated, for example regarding electric cars that are described as being barely more than experimental;
• the lectures, in audio format, are the soundtrack of a video; this has no impact on many but a significant one on others;
• some topics are drawn out and repetitions do occur; many may judge that a 36-lecture format would have been preferable.

Dated but Still Fascinating!

I don’t know whether the lecturer influenced or was influenced by politicians like Al Gore or John Kerry. Almost all of the climate predictions made by these individuals were absolutely wrong. The damage done to young minds as a result of these beliefs is immeasurable and leads the reader to question the accuracy of the other material provided in this course.

Informative - until the anthropogenic climate catastrophicism in the last chapters.

So much wonderful, interesting information, but I couldn't get past the first few chapters because of all the 'ums' from the narrator. Very disappointing, because I love this stuff, but I began to anticipate when the next 'um' would come, and couldn't listen to the material.

Too many ums

By chapter 16 it had become as evolved as it was going to be, took on variations of different subjects all going nowhere that the previous chapter(s) had not covered. Started out with a big bang but then cooled and lost its pace and message.

Unfortunately never evolved

The presenter says "umm" and "uhh" every few words, it is maddening! I gave up after a couple topics, because I couldn't take it anymore. I was very disappointed, because I love everything science.

ummm
