Geology Rocks

The fascinating, awe inspiring, beer drinking world influenced by the earth's oldest science. This blog is about all things geology. Landmarks, minerals, sedimentary deposition, pretty pictures, and humor all fall into this category.

If you ever have questions dealing with your labs or you homeworks, ask. I will be able to find you the answer if I don't know it off the top of my head.

Also, send me links and I will give you credit.

Pahoehoe Lava, Hawaii
Photograph by Steve and Donna O’Meara, Volcano Watch International/National Geographic
Pahoehoe lava flows on Kilauea volcano in Hawaii Volcanoes National Park. Unlike aa (pronounced “ah ah”) lava, pahoehoe flows relatively slowly, allowing an insulating skin to form that keeps the temperature close to 2,190°F (about 1,200°C). Aa lava, on the other hand, moves faster and doesn’t have time to develop a skin, resulting in a cooler flow with a more angular texture.
