How many tectonic plates does Earth have?

The Atlantic Ocean is getting wider every year Researchers have finally figured out why

Women in Science Day: Celebrating Southampton s female scientists

ACROSS the city, scores of scientists are making incredible discoveries and furthering our understanding of the world and all that s in it on a daily basis - but who are they? Well as today marks Women in Science day, we wanted to celebrate those who are making a difference in their fields, and who are also breaking the gender stigmatisms of the past. Set up by the United National back in 2015, February 11 marks the day in which we recognise the critical role women and girls play in science and technology. Here, we profile just some of those making a difference here in Southampton, and ask what motives them to do what they do:

Atlantic Ocean is widening due to geologic forces under Earth s crust

The tectonic plates under the Americas, Europe, and Africa are being pushed apart as the Atlantic Ocean widens year by year. New research reveals what s pushing the plates apart: Material from deep within the Earth is bursting upward at an undersea ridge in the middle of the Atlantic.  The Atlantic Ocean grows 1.5 inches wider every year. That s because the tectonic plates undergirding the Americas are separating from those beneath Europe and Africa. But precisely how and why that is happening has been a mystery to scientists, since the geological forces that typically push plates apart aren t prevalent in the Atlantic.
