These days, a key competence is the ability to critically evaluate ChatGPT outputs. I used this image of a bird's-foot delta generated by ChatGPT to assess students' understanding of the different types of delta. The ChatGPT drawing contains obvious errors, but also a major pitfall. Can you spot it?

What is the most effective way to teach earth science students? We asked our recent graduates (n=96) @eth-eaps.bsky.social @ethzurich.bsky.social.

A clear plea for field teaching and project work!

There were probably even two simultaneous mass movements!

#Geology #Educators: Here's a great example of #RelativeDating from a rockfall deposit near Flüelapass, Davos, Switzerland. I spotted this rockfall deposit two weeks ago (Nov 10th), and the rockfall must have happened sometimes after the first major snowfall at the beginning of October 2024.

Let's kick off this account with a nice geological picture from the Earth Science Collection @eth-eaps.bsky.social @ethzurich.bsky.social. Stay tuned for more!
