Matthew Agius from the University of Malta’s Department of Physics will tomorrow deliver a presentation entitled ‘Our Cracking Earth’ at St James Cavalier, Valletta at 7pm.

The Earth’s outer shell is cracked and consists of slowly moving tectonic plates that converge to create mountains, and move apart to create oceans.

In order to answer fundamental questions such as how a tectonic plate forms, thickens and ages, a team of scientists conduced a seismic experiment along the mid-Atlantic Ridge during 2016 and 2017.

They placed specialised instruments beneath the ocean across the ridge and mapped never-seen-before high-resolution bathymetry of the ocean sea floor, revealing underwater kilometres-high mountains and deep abysses.

Agius was involved in the experiment.

The presentation, organised by Malta Café Scientifique, will be delivered tomorrow at 7pm at Studio B, 

St James Cavalier, Valletta. Admission is free. For further information, visit http://bit.ly/MCSmay2018 .
