| Question | Answer |
|---|---|
| Igneous rocks that have large crystals most likely | cooled slowly below ground. Ex. Granite |
| What is a conglomerate | Clastic sedimentary rock, Which means it formed from smaller (rounded) rock pieces cemented together. Ex. pudding stone |
| Name sedimentary rocks that are well sorted | Sandstone & Schale |
| A popular chain of active volcanoes and earthquakes is often called what? | Ring of Fire |
| The ring of fire if located around what? | The Pacific Ocean |
| The sudden return of a deformed rock to its unreformed shape is called what? | Elastic Rebound |
| Igneous Rock | forms when magma or lava cools. Ex. Granite, Basalt, Obsidian and pumice. |
| the __________ is made up of the crust and rigid upper mantle. | Lithosphere |
| A seismographs does what? | records seismic waves |
| This type of lava is thicker than the precious one and cools with a rough texture. What is it | aa |
| A tsunami can be caused by an earthquake whose epicenter is where? | The ocean floor |
| What are the tectonic plates made out of? | Lithosphere |
| Name 3 pieces of evidence that support the Wegener's Hypothesis of continental drift | 1. Mesosaurus fossils South America and Africa 2. Plant fossils in Antarctica that could not be there today 3. Mountain ranges that match in different continents |
| Would you find a subduction zone at which type of plate boundary | convergent |
| The country of Iceland sits atop a _______ boundary | Divergent |
| ___________ rock form when other types of rocks are subjected to intense heat and pressure. Ex. marble & slate | Metamorphic |
| ______ metamorphism is a change in the texture, structure or chemical composition of a rock due to change in temperature and pressure over a large area. | Regional |
| This sedimentary rock often contains fossils, and forms from the remains of marine (sea) organisms. | Limestone |
| Metamorphic rock that is ____ has been exposed to tremendous pressure at tectonic plate boundaries, which causes its minerals to form layers of bands. | Foliated |
| True or False: Sediment is thicker closer to the center of mid-ocean ridge. | False |
| The ____ is location on a fault where the first motion of an earthquake begins. | Focus |
| Earthquakes with a ____ focus usually cause the most damage. | Shallow |
| The measure of strength of an earthquake is called | Magnitude |
| The strength of an earthquake is measured by | Richter scale |
| The measure of how much damage an earthquake causes is called | Intensity |
| The measure of hoe much damage is made by an earthquake is measured by | Modified Mercalli |
| Bits of rock and ash that are ejected from a volcano during an explosive eruption are called | Pyroclastic material |
| The resistance to flow of a fluid; the thickness of stickiness of magma/lava | Fiscosity |
| The Hawaiian islands formed from a hot spot in the ocean floor, unlike Japan which is considered an | Island arc |
| This type of lava flows easily and cools with ropy apperance. It is called____ | Pahoe hoe |
