I think the drake equation is bullshit. It is based off completely guessed variables. Rather than twist ourselves into knots to explain a non-existent paradox let us just accept that life is rare.

Alone in our galaxy and alone in the Universe. Not merely alone in the sense of no other technological civilizations existing but no other living planet in the Universe, at all. The total of the L value for the Universe in this context is equivalent to the lifespan of technological civilization on the Earth and that's a very small number, alarmingly small.

Too short! It says "scientists were worried about a tsunami, but none really happened." Why? (Because the quake was entirely strike-slip, so none of the plate movement resulted in significant water displacement. How hard would have it been to include a statement to that effect?).

Well reasoned, but is it universal? Pun not intended. For our life on Earth, carbon based life. But maybe carbon life cab emerge also without plate tectonics or water, maybe rich minerals could envelop the planet by vulcanism or from comets. And in the end, maybe there is non-carbon intelligent life.

Well reasoned, informative.

This viedeo is so good they showed this to us in GERMANY

They say no one has ever photographed a tsunami wave traveling 500 MPH.. the satellite images of tonga show distortion from blue to white spreading out from the epicenter.

No plastic bag?

crazy to think that just 200 years ago the US was a completely different ecosystem. There used to be bison all the way down to Florida

Amazing video! Very clear. Thanks a lot

Excellent review!

Your in a great program at UTD. I attended UTD and loved my studies in the geoscience/geophysics department in the mid 1980s. Keep up the great work.

Good video

I love your explanation and your voice are so sweet ❤and Thank you for teaching me ❤❤🙏

thats not how i remember it

i just looked ito where i put my cool stones that i found when i was 4 and found a cool volcanic geode😂😊😅❤

hnn

Thank you ..Very informative ..we need more please❤❤

Did you say "kratogen" is a "German word". It took me a second but it's obviously a GREEK word. Genos = born, birth and Kratos = strong (famously Alexander is claimed to have left his empire to "Krateros", which was the name of one of his generals but also means "the strongest one").

Scientists have an interesting outlook compared to normal people. We’ve got a massive underwater volcano that recently produced a cataclysmic explosion and essentially sent seabed into orbit. “Let’s spend several days sailing back and forward directly over it.” Then once the work was complete… “let’s stay for a bit longer and do some fishing, have fun.” 😮

I found one. It was a fresh kill with blood that has turned to red crystal. Who can I sell this one of a kind?

Awesome video. I knew about the Baltimore mafic complex but only generally. I live in Catonsville, a mile west of Baltimore city limits. We have all kinds of amazing rocks here. Interestingly, I have a small stream in my back yard. At one end, you'll find big, chunky, igneous rocks including lots of gabbro. Well, it's pyroxene mixed with bits of clear quartz, so I think it's gabbro. At the other, you'll find clay, guessing weathered/dissolved feldspars, and gravels. Also, huge amounts of iron oxides, some sulfides (e.g., arsenopyrite, chalcopyrite), some manganese oxides (I believe), and other rocks that I'm not sure about (but take a great polish). If you look hard enough, you'll even find small amounts of gold and platinum group metals. Nothing economically interesting, but still fun.

thank you Dr. it was a great help to me

I have been subscribing to Black Earth Zeolite tincture...but recently have heard that the Master Peace brand...provides a better natural supplement. Any thoughts on this?

It moves as a toroidal shape kind of.

Finally, you have scratched a long itching questions - how did the continents form?? Itch soothed, bravo!

Dr. Manton was the best! Thanks for everything professor!

got 100% in the quiz thanks for the lecture !

Hi, please I need help in getting a PHD position in Marine Geosciences or it related in your University or any country. I am currently about rounding up my Masters program in Marine Geosciences in Israel. I have applied to schools upon school's but no positive response from the Professors. It's usually no funding I get as replies. Please help me

Very interesting! Thanks for posting. Isis Geologist - Brazil

Ah but I HAVE studied it.

I went over there

When I hear 2.6 million years ago is when I stop watching.

It's foolish to deny that there have been countless cycles (and "resets") of humans all down through the millenia

Not a single lake in Maryland is natural; they are all 100% man-made.

small vulcano?!?!? nah.

Do you guys ever have the air tested there?

Wait so its nothing to do with the molecule properties or anything like that? Its just because they are so small and sharp?

Great story ,cheers

I've lived here my whole life and never even knew about this. Pretty damn cool!

Lost me at 500 million years ago…

Many geologists see proof of plate tectonics even before 3.5 billion years. In the Greenland Isua belt in the slave craton in NOT (Canada). Three billion years old eclogite have been found with ophiolite showing colliding continents before the Proterozoic. I believe the traces are convincing for at least a partial plate tectonic regime in the Archean.

Very cool

I lived in those projects between 1994-1997 I remember a lot of people who were born there getting Lead Checks from the government at the time. I hope they are still getting them. And I hope there is nothing wrong with me for being a child playing in all that dirt back then.

Muchas gracias.

Please lose the ruinous obnoxious noise. I wanted to watch this.

I’m completely confused 😭😭

Thank you! Can you provide us with a link to the paper(s) about this?
