The geological effects that were reported where ground fissures, uplift, subsidence, liquefaction, and landslides.. Deformation. The process of when a rock changes because of stress. Compression. -rocks push together (squeezing). Tension. -rocks pull away from each other (stretching). Rock layers bend when stress is placed on them. But when the stress is placed on rocks, they can reach their elastic limit and break. The Earths crust . The earths crust is in constant motion.. Volcanoes and earthquakes arise as sections of crust push . toghether. or pulled apart. Volcanoes and earthquakes are more common in certain parts of the world. By monitoring ground vibrations scientists can sometimes. Earthquake. – shaking and trebling that results from the movement of rock beneath Earth’s surface.. Plate movement causes earthquakes from stress and faults in Earth’s crust. When the rock breaks earthquakes happen. Comparing and contrasting earthquakes.

Earthquakes can cause intense vibration of the ground, soil liquefaction, and distortion of the ground. Earthquakes can happen almost anywhere but are most common along the boundaries of the tectonic plates. Earthquakes are primarily caused of movement of the tectonic plates. It lasts more than a few seconds.. Earth’s Dynamic Crust. Original Horizontality (law of superposition):. Assumption . that sedimentary/igneous rocks form in horizontal layers . Deformity.
