Igneous, Sedimentary and Metamorphic

Who better, than a pet rock, to guide you through the intricate field of Earth Sciences.  They come from the earth and have cousins all around the world. Let me introduce them.

igneous rock

Iggy – short for igneous is the youngest of the bunch. He was born in an explosion of great magnitude in the Pacific Northwest in 1980. He has cousins all around the world, but most of his first cousins are still on the slope of Mt. St. Helens in Washington. 







sedimentary rock

Sedim – short for sedimentary is very complex. She is mysterious about revealing her age. Her many layers tell the stories of different moments in her history which spans a great length of time. Some of her cousins have been known to gather at the base of Devil’s Tower.







metamorphic rockMorph – short for metamorphic, is very very old. But for most of his long life he was hidden in the depths of the earth. He helped to form one  of the largest mountain ranges in the United States, The Rocky Mountains, but didn’t see the light of day until much of what was causing the pressure on him, had eroded. his cousins go back for generations in the Appalachian mountains, which used to be very large, but are now just the remaining metamorphic rocks that formed their core.
