Faces of Earth - Building the Planet

Prepare to witness the explosion that formed planet Earth, and travel back in time to explore the evolution of the Earth we know today. We'll see new technologies that allow today's geoscientists to strip back layers of the Earth, to see what previously could only be imagined. This is episode 1 of the 4 part Faces of Earth series.

Every aspect of earth science is fascinating, that’s why I became a geologist. I was hooked from the first introductory course I took to meet a science requirement! It’s a wonderfully fulfilling career, I hope college students consider it!

[JulieReizner]

Used in my geology courses at Northern Kentucky University.  Thank you!!
2 min: geological imaging
8 min: 4.5 Ga - formation of Earth, magnetic field, layers of the Earth
17 min: 3 Ga - abiogenesis, cyanobacteria, banded iron formations
24 min: 2 Ga - rise of complex life, extinction events
31 min: coal and oil formation and exploration, gas trap model

Amazing presentation of uniqueness of Earth in this Solar System and Universe. It's formation and beginning of life in early Earth environment reflected by the present glimpses of rocks formations. Thanks for sharing.

Some really good science in here. But there's also some speculation regarding the nature of early earth and the origin of life. I'd appreciate it if there were a clear line drawn between what we know and what we must speculate about.

I'm wishing Brian Forester was my history teacher while growing up, I would of like to have learned lots of this stuff while younger, but hey...never to late to learn

Error. RADAR does not use sound.RAdio Detection And Ranging. It uses radio signals. SONAR uses sound. SOund Navigation And Ranging used by marine mammals for navigation and prey location, destroyers in locating submarines, and submarines for depth below the keel and other functions.

[SadieMorgan]

yes Geology rocks and so does Science.... love them both <3

[nickrider]

Love geology, it affects us all and piecing together evidence of past events and climates is hugely fascinating 🙂

[slappyusa]

at 36:03 they state that Radar uses sound, that is sonar. Radar uses radio waves which are light waves but not in the visible spectrum. Radar = RAdio Detection And Ranging

[granskare]

is this the old U-2? sorry, when I saw it take off, I knew it went with the U2. Later, I was very disappointed that the bit about the U-2 did not carry on...what happened?

[travyoso]

doing this for school, i wish my teacher sent videos with transcripts

[soosistvan]

Nagyon szép, lebilincselő témájú ez a film! Reklámblokkok nélkül meg nagyon élvezetes is nézni!

[brooklynct]

at 36:00, the narrator compares LIDAR to RADAR, but incorrectly attributes sound to RADAR instead of radio waves. Colossal mistake.

Normally I hate animations, because they tend to be cheesy and poorly done. The animations for this video, however, were IMO beautifully done.

[karenjones]

If only this kind of effort and these kind of technologies were applied to renewables we would have had them years ago.

[robertmccabe]

A quick question.if the earth’s magnetic field stops the solar wind from stripping away our atmosphere, why has this not happened on Venus which is much closer to the sun? Being a much closer, it receives much more intense solar winds and other sun generated fields than earth?

36:02 - radar does not use sound, that would be sonar. Radar uses radio waves.

[ezr]

It would be nice to have two versions of these shows, one with no music and sound affects and the movie noise version so children can stay entertained

[cowboygeologist]

As a retired Geologist, and former electronics tech before that, this is a fascinating video. BTW, Nevada is pronounced just like you spell it. NevADa, not Nev-ODD-a.

DON'T forget to add the electrical scarring, and petrified wood of the grand canyon. As well as the electrical scarring of the sphynx.
