| An upward fold is called a (n) _________. | anticline |
| The fastest moving seismic waves are ______. | P waves |
| The squeezing together of rocks by stress is called _______. | compression |
| All volcanic material is ________size. | different |
| Today people are ________killed by volcanic eruptions. | sometimes |
| There _____ a relationship between plate tectonics and volcanoes. | is |
| Magma is forced upward because its _____ than the surrounding rock. | less dense |
| A volcano _______ forms when a volcano's core erodes. | neck |
| Scientists who study earthquakes are called richters. | False, seismologists |
| The strength of earthquakes is measured according to scale called a seismograph. | False, richter |
| A great sea wave is called a tsunami. | True |
| The point on the Earth's surface directly above an earthquake point of origin is called the focus. | False, epicenter |
| An instrument that detects and measures seismic waves is called a seismograph. | True |
| Ship Rock, New Mexico is really a volcanic neck. | True |
| Mount St. Helens, Washington is a composite volcano. | True |
| Yosemite National Park in California is a cinder cone. | False, batholith |
| Kilauea, Hawaii is shield volcano. | True |
| Paricutin, Mexico is a cinder cone volcano. | True |
| The name of the scientist who proposed the Theory of Continental Drift is Alfred Wegener. | True |
| The topmost solid portion of the Earth is called the lithosphere. | True |
| A movement of material caused by differences in temperature is called radiation. | False, convection current |
| another name for a transform boundary is a transform fault. | True |
| Pangaea means "all land" | True |
| Dikes are formed when ______. | magma enters a vertical crack and hardens |
| A laccolith is created when ________. | magma in a sill pushes up to form a rock dome |
| A mountain that forms when layers of lava and ash erupt and build up is a ________. | volcano |
| Hot spots occur at ______. | locations not at plate boundaries |
| Kilauea in Hawaii is the worlds most ________volcano. | active |
| A deep crack that runs along the center of a mid-ocean ridge is called a | rift valley |
| The earth's magnetic pole have _______ themselves in the past. | reversed |
| Trenches are found mostly ________ continents. | close to |
| All plates contain _______ crust. | oceanic |
| Remains or traces of plant or animal life are called ______. | fossils |
| Where would the safest place to be during an earthquake inside or out? Why did you choose your answer? | outside, because there is less stuff to fall on you |
| Where are most volcanoes found and why? | Weak places in the crust (boundaries, hot spots) because this is where the magma can come up |
| How did similar fossils found is different help to support the theory of continental drift? | Similar Fossils were found in both places and they could not have traveled across the ocean, therefore continents must have been altogether. |
