Without understanding what it is, we often hear the phrase “down to the Moho”, meaning very very deep. The Mohorovicic Discontinuity, commonly called the “Moho” is recognized as the boundary zone between Earth's crust and the mantle.
This boundary marks a change in seismic-wave velocity from the crust to the uppermost mantle within the (lithospheric) plate. This boundary was discovered by Andrija Mohorovičić, a Croatian meteorologist-turned seismologist, after an earthquake in Croatia in 1909.

I knew some about the Moho. I thought this would be a review. But I learned a lot. Sometimes people are bewildered when science talks about poorly understood subjects. As a retired scientist, I look back and see that I have spent most of my career looking for science that is not finalized. That is where I could make the most contribution and find the most personal satisfaction. These last 40 years where so many people want to be researchers and publications have become required even at the community college level, I deliberately chose education as most in need of workers. So when I see exceptional contributions to education, such as this video, I try to make specific and lengthy comments. Thanks for the excellent video.

this is the best youtube channel, I love your videos. I'm a student of Geology and I hope to become a seismologist one day

Thanks a lot for taking the time to say that. It makes it worth doing it...for people like you!! (BTW, I was a geologist before animating seismology...which i didn't understand very well.)

It doesn't have enough subscribers. Too underrated. It needs a million of subscribers.

I thought this KZfaq Channel belongs to a group of Geologists.

@@aehighfmcolinchin No, professional scientists are too busy pursuing funding and tenure to contribute to education. That deficiency is severe in physics and math, but not so bad in geology. But don't be disappointed: less than 100 years ago there was virtually no funding and tenure was more . . . dependent on a person's social status. The world and its surface changes.

It's not really relevant but I still want to point something out. The region where Mohorovičić was born was called Croatia-Slavonia and it was part of the Habsburg Monarchy at that time. Also at 2:59 you use today's borders but it's 1919 we're talking, the borders were different.

You're right - that's not relevant in any way.

I thought for sure it was going to be named after a Hawaiian word.

the bible is amazing! already affirmed what came to be discovered only in the 20th century by this great name of seismology. read the Bible, it is also Science! Book of Job chapter 28.5
