Rift! Geologic Clues to What’s Tearing Africa Apart

East Africa is one of the most geologically intriguing places on the planet—a place where the African continent is literally ripping apart. Deep rift valleys, active volcanoes, and hot springs are dramatic evidence for the powerful forces deep within the earth that are slowly reshaping the continent. Join geochemist David Hilton on an adventure to the East African Rift Valley and learn how he and his colleagues utilize geologic samples to understand this dynamic region of our planet.

My love of geology, rocks, minerals and nature go back to my childhood days when being poor. I had to find something to do so anything nature, I gravitated to. Rocks were so fascinating to me. I could sit for hours and study their composition, shapes and textures even though I didn't know much of anything at that age. This is so fascinating and so informative and I thank you for its content.

Best video about East Africa tectonics. He is talking so everyone can understand.

Beautiful lecture(er). You can see the speech skills of this guy how he explains everything to the regular public with simple terms and great slides.

Wonderfully explained about Rift Valley of east Africa

I have watched this three times and every time I learn something new. Thanks UC TV

Loved this presentation ! Very informative and he kept me interested in a subject I had assumed, would put me to sleep. I look forward to following his work and hope he can get enough heat from magma to cook a hot dog to go with the local beer

I love this lecture. I particularly like hearing the description of our understanding of the structure of the earth and how we "think" it is run by mantle plumes. Obviously I am not here to promote any other theories, I simply enjoy hearing that we dont necessarily know for sure; it's just our best proposed theory.

Oh look the comment section is full of pseudoscience, what a

Very interesting. Thank you. Old Mother Earth. What a place. Full of surprises. Not sitting around on her duff interacting on Facebook.

[giridharmadhuranthakam]

Good study on the formation of rifts and creation of new oceans. Very informative.

[Mainneli]

It's happening now. Large cracks have appeared on the surface.
Thanks for the insights

I collect mantle xenoliths from all the world. I am mad about them. So beautiful...
Thanks for this beautiful lecture.

EXCELLENT PRESENTATION PRESENTOR! THANK YOU

[XDRONIN]

Very interesting lecture, one thing to note is that from the maps shown, this rift seems very close to where anthropologists place the origins of the human race in East Africa.

Explained very simple but scientific based style
