Three Types of Rocks Igneous Sedimentary Metamorphic
{"Image DocumentName": "Three Types of Rocks Igneous Sedimentary Metamorphic", "Image ImageDescription": "Igneous is the most common rock type in earth s crust. It is solidified from magma extruded onto the surface from volcanic vents. Quick cooling of magma produces fine-grained rocks. Basalt. Slow cooling of magma produces coarse-grained rocks. Granite. Igneous rocks are composed of magma that solidifies directly into rock, either after being ejected above the surface of the earth or cooling underground. Most of the rocks in the Earth s crust are igneous (including most rocks in Seattle area soils).", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
