A new ocean is forming in Africa along a 35-mile crack that opened up in Ethiopia in 2005. The crack, which has been expanding ever since, is a result of three tectonic plates pulling away from each other.
It’s thought that Africa’s new ocean will take at least 5 million to 10 million years to form, but the Afar region’s fortuitous location at the boundaries of the Nubian, Somali and Arabian plates makes it a unique laboratory to study elaborate tectonic processes.
There are still some big unknowns, including what is causing the continent to rift apart. Some think that a massive plume of superheated rocks rising from the mantle beneath East Africa could be driving the region’s continental rift.
Each plate boundary in the Afar region is spreading at different speeds, but the combined forces of these separating plates is creating what’s known as a mid-ocean ridge system, where eventually a new ocean will form.
The three plates are separating at different speeds. The Arabian plate is moving away from Africa at a rate of about 1 inch per year, while the two African plates are separating even slower, between half an inch to 0.2 inches per year.

Please watch this. It isn’t just a story of resilience & recovery. It’s also a reminder of the opposite —how easy it is for us to damage entire ecosystems, of which we are a part, with the human-caused loss of species. It affects everything. HT @MikeHudema
The Halifax Road Hammers’ women’s team defended their Cabot Trail Relay title this weekend. And they broke the all-time women’s course record, finishing in 19hrs:18min:7sec.
Hey @TILTHRCE here’s a leveled up classroom chromebook hack- add a basket on bottom to hold powerbars and charging cords, only plug part is exposed! Less cord mess and easy to plug chrome books back in!
Just picked up my goodies from my Pets in the Classroom grant!
Teachers in pre-primary to grade 9 can apply for a grant to get a classroom pet!

Reporter @SyperekMurphy was at a park in Halifax yesterday, talking to a man living in a tent, when Junasia Johnson-David and Teirah Slawter handed the man a bagged lunch. The teens used their pocket money to buy food for 60 people. "Just something to do on a hot day."
