Movie Lab Blog

The last few weeks in class we have watched movies during our lab.  My favorite was the one about all the tectonic plates and earthquakes and volcanoes.  The movie was very interesting and was the most entertaining of all the movies in my mind.  It was cool to see all of the volcanoes and learn about all the eruptions and quakes of the past.  I liked learning about how certain places live around the volcanoes and are able to thrive right next to giant volcanoes.  The earthquake in San Francisco was very interesting to learn about.

Pumice

Pumice is a volcanic rock that is a solid lava that has been ejected from a heated up and highly pressurized volcano.  It can be created by a mix of lava and water because the water cools and depressurizes to create this rock.  Pumice can float on water at first, and pumice is actually considered a glass.  This is because it has no crystal structure.  One of the main uses of pumice is in concrete.  It is also used to take off calluses and other dry or lose skin.  Pumice is very low in density.

El Capitan, Yosemite National Park, California

The rock formation is located in Yosemite National Park in California.  At its tallest, this rock is about 3,000 feet tall.  It is said that the formation was formed over many years of glaciation.

The rock type of El Capitan is mostly granite. Igneous rock forms the upper part of the rock formation.
Granite is usually a construction rock.
