What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

I was shocked about "electric rocks" but it seems to be just a fancy word for "metallic minerals".

The article also says

Geiger determined that natural mineral deposits on the ocean floor, called polymetallic nodules, contained elements including cobalt, nickel, copper, lithium, and manganese—all of which are critical components of batteries.

I think I have seen some video about an Australian entrepreneur who wanted to "harvest" those things off the seafloor, to great concern of environmentalists.

I guess it was unexpected that rocks can create a functional battery, and not have been drained after all this time.
