| Question | Answer |
|---|---|
| currently erupting, shows signs of erupting like new gas emissions, likely to erupt in the near future, or has erupted at any time during recorded history | active volcanoes |
| not expected to erupt ever again | extinct volcanoes |
| have not erupted for 10,000 years, but may erupt again | dormant volcanoes |
| the leftover radioactive material produced by nuclear research, medical treatment, and other nuclear technology | nuclear waste |
| a feature on the surface of the Earth ranging from the plains, plateau's, mountains, hills, valleys, etc. | landforms |
| liquid melted rock beneath the earth's surface and released during volcanic eruptions | magma |
| simplified representation of reality used to examine aspects of the natural world | model |
| 2,800-5,200 km below the earth's surface, liquid made of iron and nickel, temp: 2,800-5,200'C | outer core |
| 5,200 to 6,400 below the earth's surface, solid, made of iron and nickel, temp: over 6,000'C | inner core |
| 0-40 km on the earth's surface. Many kinds of rocks. Temp.: 0-700'C | crust |
| magma that has erupted onto the Earth's surface | lava |
| crust and upper layer of mantle, stone, first 100km below Earth's surface | lithosphere |
| 40-2,800km from the Earth's surface, next layer below the crust, upper part is solid, lower part is liquid . Made up of iron, magnesium and silicon compounds. Temp: 700-2,800'C | mantle |
| each part of the model has a size that is accurate relative to another part. 1cm=800km | scale |
| smallest and most common volcanoes | cinder cones |
| usually large, broad, fast moving, less-gassy magma | shield volcanoes |
| has explosive eruptions, result of more gassy magma | composite volcanoes |
| the periods of thousands, millions, and billions of years ago | geological time |
| scientists who use evidence from rocks and fossils to understand when events occurred in the history of life | paleontologist |
| cold blooded air breathing vertebrates with scales, that typically lay eggs | reptile |
| super continent that was in approximately 250 million years ago in which the current continents are connected | Pangea |
| 7 large landmasses on Earth | continent |
| Idea that the continents slowly moved away from each other or drifted apart. Pangea the super continent to current placement of continents | continental drift |
| water, gravity, and heat are responsible for this, moving rock and soil from one place to another | erosion |
| Change earth's surface by moving rock and soil particles from one area to another | deposition |
| a mass of ice on land | glacier |
| underground canals, caves, sinkholes, and a rough and bumpy ground surface form | karst topography |
| created by association with plate tectonics | landform |
| shaped by the action of water, gravity, and heat | landscape |
| calcium carbohydrate is the maine mineral broken down and dissolved in water | limestone |
| what keeps humans on the Earth, pulls things down to the Earth's surface. A force that affects all materials and causes them to be attracted to each other | gravity |
| attracted to each other, like magnets, stick together | Attractive |
| pushes things away, like when you put a magnet another magnet and they bush away from each other | repulsion |
| hot, molten material in the magnetic field with an effective distance, navigate for animals during migration ( invisible, 2 ends, north and south pole, attract and repeal, cause elements that have those features to have their own magnetic field ) | Earth's magnetic field |
| extends only a short distance from the magnetic core, depends on size and strength | effective distance |
| one side of this rock attracts a pole and the other side of this rock attracts the other pole | lodestone |
| responds to the Earth's magnetic field | Navigational compass |
| The Earth's surface is broken into large sections called plates, these plates extend down into the lithosphere | plates |
| a thoughtful, testable, explanation of all relevant observations | theory |
| quantitively used to measure the strength of an Earthquake at the point were rocks break, each increased of one on this scale is equal to 30-fold increase of released energy | Richter schale |
| contains a thin needle-like pen that records the movements detected within the Earth on a role of paper | seismograph |
| lines recorded on the paper that records the movements detected within the Earth | seismogram |
| created by colliding plates, what happens on this boundary depends on the type on lithosphere | convergent |
| plates that are spreading apart | divergent |
| process of one plate moving below another plate | subduction |
| two plates that are sliding past each other | transformation |
| within the Earth's mantle, occurs when there is a temperature difference within a subduction like magma, causing it to move in a curricular pattern | convection current |
| a subsea chasm extending along the crest of a mid-ocean ridge, locus of the magma upwellings that accompany seafloor spreading. | rift valley |
