I am the force that will deform rock. I am the area in which a rock breaks. I am the stress that squeezes rock layers together. I am Stress that stretches rock layers apart. I am Stress that causes the rock layers to slide by each other. I am the fault that is caused by compression stress. I am the fault that is caused by tension stress. I am the fault that is caused by shear stress. I am energy that moves outward, in every direction, from the center of an earthquake. I am the type of seismic waves that move through the ground in a back and forth motion. I am A seismic wave that moves through the ground in an up and down motion. I am A type of seismic wave that moves on top of the ground in a rolling motion. I am the point on the earth’s surface directly above the earthquake center. I am the center point of an earthquake. I am an earthquake generated ocean wave. I am the area in which magma rises to the surface, cracks it and pushes plates apart. The magma flows out of the cracks and forms a volcano. I am the area in which plates collide and the more dense plate is forced to sink and melt. I am the volcanic zone that is caused by areas of the mantle that are warmer than other areas. I am the magma that forms dark colored rock when it cools. It has a low viscosity and does not erupt violently. I am the magma that forms light colored rock when it cools. It has a high viscosity and is very explosive. I am the ability of a substance to flow or the silica content of magma . I am a broad volcano with gently sloping sides, built by nonviolent eruptions of basaltic magma. I am a volcano that forms from volcanic material that is violently erupted and piles up into a steep sided cone mountain. I am a volcano that alternates between violent tephra eruptions and nonviolent lava eruptions. Most violently erupting type of volcano. I am hot melted rock above Earth's surface. I am an explosive eruption of hot gases, and tephra that causes huge amounts of destruction. I am lava and or other volcanic material that harden into volcanic ash, cinders, or bombs. I am a volcano that is erupting or has shown signs that it may erupt in the near future. I am a "sleeping" volcano that is in an active zone. This type of volcano can awaken at any time. I am a volcano that has very little chance of ever erupting again. ANSWERS: Who is stress? Who is a fault? Who is compression stress? Who is tension stress? Who is shear stress?
