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.
PLEASE NOTE: When you purchase this title, the accompanying PDF will be available in your Audible Library along with the audio.

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• Earth science is a dynamic field so that some information conveyed is clearly outdated, for example regarding electric cars that are described as being barely more than experimental;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!

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