| Question | Answer |
|---|---|
| Rock that forms when magma or lava cools ex. granite,obsidian,pumice | Igneous |
| An igneous rock that has big crystals must have cooled? ex.granite | slow |
| Rock that is formed from rounded rock pieces cemented together. | conglomerate- which is a clasict sedimentary rock |
| Rock that is formed when other types of rock are subjected to an intense heat and pressure ex. marble and 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 |
| name sedimentary rocks that are well-sorted: | shale,sandstone |
| This sedimentary rock often contains fossils,and forms from the remains of marine (sea) organisms | limestone |
| metamorphic rock that is _____ have been exposed to tremendous pressure at tectonic plates boundaries, which cause its minerals to form layers or bands | foliated |
| The _______ is made up of the crust and rigid upper mantle. it's what tectonic plates are made of. (sounds like my main origin) | lithosphere |
| Name three pieces of evidence used to support the wagner's hypothesis of continental drift | -mountains -fossils -coast lines |
| you will find a seduction zone at what boundary? | convergent |
| The ring of fire--a mountain chain of active volcanoes and earthquakes-- is located around the ____ ocean. | pacific |
| The country of ice-land sits atop a_____plate boundry | divergent |
| True or False- sediment is thicker closer to the mid-ocean ridge | false |
| The sudden return of a deformed rock to undeformed shape is called? | elastic rebound |
| The____ is the location of a fault where the first motion of an earthquake begins | focus |
| earthquakes with a _____ focus usually cause the most damage | shallow |
| The instrument used to record seismic waves is called | seismograph |
| A tsunami can be caused my an earthquake whose epicenter is on the_____ floor | ocean |
| The measure of the strength of an earthquake is called____ and it is measured on the ______ scale | magnitude,Richter |
| The measure of how much damage an earthquake causes is called ______and it's measured on the__________________scale | intensity,modified mercali |
| bits of ash and rock that are ejected from a volcano during an explosive eruption are called __________ material | pyrocalastic |
| The resistance to flow of a fluid; the thickness or stickiness of a magma/ lava? | viscosity |
| volcano: Hawaiian islands | type of volcano- Sheild type of magma/lava- mafic origin of magma-Oceanic viscosity-Low type of eruption-quiet |
| mt.st.helens | type of volcano-composite type of magma/lava-felsic origin of magma-continental velocity- high type of eruption-explosive |
| The Hawaiian islands formed from a hot spot in the ocean floor,unlike japan which is considered an? | island mark |
| this type of lava flows easily and cools with a ropy appearance. Its is called? | pohoehoe |
| This type of lava is thicker than the previous one and cools with a rough texture. It is called? | aa |
