With its Aditya-L1, India may have proved the breadth and versatility of its space programme that has led to Isro being marked as a space collaborator for programmes with far bigger budgets like those of Nasa and others. (Image: PTI)

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.

Monsoonal havoc particularly in Himalayan regions reminds and invites the debate of vs vs . Policy makers and planners must ponder upon these concepts to unfold the truth of vulnerability and disaster.
These thoughts have long roots in Geography discipline (marginalized discipline). But the lesson and essence of these concepts have not been taken up seriously by the so called stakeholders of the environment.

A first-of-its-kind study suggests that isotope analysis could be used to pinpoint sources and sinks of atmospheric methyl chloride.
