Morriss P.T. Review
Study Guide for Exploring Plate Tectonics Unit Exam
| Question | Answer |
|---|---|
| Describe and draw a diagram of each type of earthquake wave created each time you moved the spring. | P-Waves: are primary waves, move faster, have a “push and pull”movement, compress and release movement. S-Waves: are secondary waves, move slower, “side to side”, perpendicular to direction of wave, snakelike movement. |
| Describe the relationship between earthquakes, volcanic eruptions, and tectonic plates. | Earthquakes and volcanic eruptions tend to happen along where the tectonic plate boundaries meet with each other. When plates collide or slide, they cause the earthquakes and volcanic eruptions to occur. |
| Draw and describe the composition of the four main layers of the earth. | See foldable in your notebook. Crust(rock), Mantle (Upper is solid, Lower is liquid), Core (Outer is liquid and inner is solid) |
| What is the magnitude of an earthquake? | The magnitude of an earthquake is the amount of energy released. |
| What is happening to the plates along the San Andreas Fault? | The plates are sliding against each other, it is a transform boundary that results in a strike-slip fault. |
| What landform is created when two continental plates collide? Give an example. | Mountain Ranges. For example, The Himalaya Range, |
| What is the intensity of an earthquake? | The intensity is the kind of damage done by an earthquake, such as buildings damaged and people harmed. |
| What are characteristics of old fault-lines? What forces are at work? (Think about what you did during Inquiry 7.1.) | Old fault-lines have smooth edges with very little frictional resistance taking place. When they slide against each other at transform boundary lines, there is very little earthquake activity. |
| What is the type of plate boundary that involves the plates moving apart and causes continental rift and the mid-Atlantic ridge to form? | A divergent boundary |
| What is the type of plate boundary that involves the plates colliding into each other and causes mountains, trenches, and volcanoes to form? | A convergent boundary |
| What is the type of plate boundary that involves plates sliding (grinding) past each other and causes strike-slip faults? | A transform boundary |
| This type of volcano is steep, pointed, and formed from sticky, slow moving lava flows and ash eruptions. This, along with rock fragments, build up the sides of the volcano. | A composite volcano |
| This type of volcano has broad, gentle slopes formed from runny lava flows. Less viscous(runny) lava flows tend to build enormous, low-angle volcanoes because it flows across the ground easily. | A shield volcano |
| What is the difference between magma and lava? | Magma is molten rock under the Earth’s surface and lava is molten rock on the Earth’s surface. |
| Frequent earthquakes, the emission of gas and heat, and molten rock appearing in and around the vent of a volcano are all signs of what? | That a volcano is about to erupt. |
| How do the speeds of earthquake waves compare to each other. | P-waves are faster and appear first on a seismograph, S-waves are slower and appear second on a seismograph. |
| This type of volcano tends to be explosive with thick magma and high gas pressure that shatters the rock into small pieces. These small pieces accumulate around the opening or the vent of the volcano, creating a bowl shape. | A cinder cone volcano |
| What are characteristics of new fault-lines? What forces are at work? (Think about what you did during Inquiry 7.1.) | New fault-lines have jagged, rough edges with a large amount of frictional resistance taking place. When they slide against each other at transform boundary lines, there is high earthquake activity of greater magnitude and intensity. |
| What are some destructive characteristics of volcanoes? | Ash fall causing suffocation and buildings to collapse, pyroclastic flow and lahar that destroy entire regions, causes change in temperature, tsunamis, and wipes out entire forests. |
| What are some constructive characteristics of volcanoes? | Geothermal energy source, hot springs, ash is used as fertilizer, creates new landscapes and islands, and provides natural resources such as obsidian, pumice, and wood. |
