Types of Volcanoes

There are three main types of volcanoes:

Composite – Also called “stratovolcanoes”, these are generally composed of lava flows, mudflow deposits, lava domes, and pyroclastic deposits. They can be active for long periods and erupt periodically. One famous example is Mount St. Helens in Washington State, which erupted back in 1980 and destroyed forests and towns.

Cinder Cone – The most common type of volcano in the world, this type is likely the first picture you imagined as a child. True to their name, cinder cone volcanoes are steep and composed primarily of dark cinders. Parícutin Volcano is one of the few volcanoes scientists have been able to study the lifespan of, as it appeared in 1943 and went dormant in 1952.

Shield – These volcanoes are broad, gently sloping with a wide base (similar to its namesake). Some of the most famous examples lie in Hawaii: Mauna Loa and Kīlauea. In fact, these two volcanoes are a couple of the most active ones on the planet!

Week 5

  What did you do in lab today?  Ted came in and answered any questions we had for the test.  We gave our presentation first.   Crater:  A round hole on the ground made by a rock from space hitting a planet or moon.   Comet:  A space rock made of ice and dust that grows a tail when it gets near the Sun.   Meteorites:  Space rocks that fall to Earth and land on the ground.   Meteors:  A streak of light in the sky caused by a space rock burning up in Earth’s air.     What is the difference between a meteor and meteorite?        Ann Hodges only lady to survive a meteorite hitting her       Galaxies      Galaxies are made up of planets, stars and lots of gas held up by gravity     240 million years to orbit the milky way once     Large galaxies can cannibalize smaller ones      Galaxies can collide    Black Holes    Objects...
