  1. What makes up plates? • The term “plate” in geological terms means large slab of rock. • The term “tectonic” is part of the Greek root word for “to build” • Earths lithosphere is made up of individual plates which are small and large pieces of solid rock • The broken apart pieces slide assed each other on top of Earths fluid mantle which create different late boundaries and form the earths landscape

  2. Types of Volcanoes • Cinder Cone Volcano: steep sided cones made up of basaltic fragments. They're small volcanoes, usually only about a mile across and up to around a thousand feet high. • Composite Volcano: consist of layers of solid lava flows mixed with layers of sand- or gravel-like volcanic rock called cinders or volcanic ash. tens of miles across and ten thousand or more feet in height, they have moderately steep sides and sometimes have small craters in their summits. • Shield Volcano: can be hundreds of miles across and many tens of thousands of feet high, have low slopes and consist almost entirely of frozen lavas. They almost always have large craters at their summits.

  3. Volcano formations • Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. As This continues over time, it will build bigger and bigger. • Composite volcanos are develop from repeated explosive and nonexplosive eruptions of lava fragments and lava that build up layer by layer. • Shield volcanos are form from nonexplosiveeruptions of flowing lava. • Cinder cone volcanos are formed by  build from lava that is blown violently into the air and breaks into fragments.

  4. Earthquakes • Earthquakes are a sudden and violent shaking of the ground • They are a result of movements within the earth's crust or volcanic action. These movements are caused by the plates squeezing or stretching passed each other, and huge rocks form at their edges and the rocks shift with great force, causing an earthquake. • Scientist use the Richter Scale to measure the intensity of an earthquake. The Richter Scale originated in the 1930s and was invented by Dr. Charles Richter, the numbers on the Richter scale range from 0 to 9.
