Plate Tectonics, Volcano and Earthquake Webquest

Standard:S8.D.1.1.2Describe natural processes that change Earth’s surface (e.g., landslides, volcanic eruptions,earthquakes, mountain building, new land being formed, weathering, erosion, sedimentation, soil formation).

Objective:Learn and explore basic background information of Plate Tectonics, Volcanoes, and Earthquakes.

Instructions:Go to each of the websites indicated below. Answer the questions or complete the requested responses about each of those sites. Make sure your explanations to the answers as complete as possible.

Plate Tectonics

c.Click “Next”. Fill in the gaps to learn how Earthquakesform.

i.Earthquakes developintheof the earth. The inner part of the earth containsmassive . Some of this energyescapesthrough and other volcanic activity, but the bulk ofitis within the earth’s inner part, contained in thecrust.

ii.The earth’s outer crust is held in place likeacompleted, with roughedgesandlines.Theenergystoredherecausesthepiecestoslide,glide,knockandmove around each piece. These pieces best describe what wecall‘ ’.

iii.After a period of time, the built up energy and movementcauseshugein the plates, and thereismassive on the fault lines. This intense pressure resulting from energy build up causes the fault lines give way, and plates move over, against or apart from each other.

iv.Thereisanat this point. In theformof(like water ripples) the escapingenergyradiates from the fault in alldirections.

The seismic waves shake the earthastheythrough it. When the waves reach the earth’s surface, theyshakethe and anything on it, tearingdown houses andstructures.
