Magma Chamber- the chamber below the volcano in which magma is stored Crater- Central vent of volcano; funnel-shaped pit Magma- lava that has not come to the earth s surface yet Caldera- When a magma chamber empties and the roof collapses, causing ground to sink Vent- opening in the side of a volcano in which lava can seep out 2) Shield Volcano- Built of layers of lava from non-explosive eruptions - Spreads over wide area - Over time, volcano will have gentle sloping - Can be very big Cinder Cone Volcano- Small cones made up of pyroclastic material Forms steeper slopes with narrow base Erupt for short period of time, often in clusters Erode quickly because lava doesn t fuse together
Composite Volcano- Most common type of volcano - Form with both explosive and non-explosive eruptions - Forms alternating layers of lava and pyroclastic material - Broad base and steeper sides toward the summit 3) Strike-slip fault- slide past horizontally - When released, causes moderate, shallow earthquakes Reverse Faults- slid past vertically When released, causes strong, deep earthquakes
Normal Faults- Pull apart from each other - When released, causes weak, shallow earthquakes 4) P Waves (Primary waves)- can travel through solid material - Fastest waves, arriving first to scene of destruction S Waves (Secondary)- can t travel through solid material, only liquid Second fastest wave, arriving second to scene
Surface Waves- Moves ground up and down in circular, forward motions - Normally come after the secondary and primary waves - Most destructive type of waves 5) Seismographs- instruments located at or near the surface of the Earth that recode seismic waves Seismogram- Tracing of the earthquake motion created by seismograph Epicenter- The point on the Earth s surface directly above an earthquake s starting point Focus- The point inside the Earth where an earthquake s epicenter and its focus Seismic Gap- Areas along a fault where relatively few earthquakes have occurred Shadow Zone- Area on the Earth s surface where no direct seismic waves from a particular earthquake can be detected.

Mesosphere- Below asthenosphere
-
Extends as far down as the earth s core
Outer Core- Liquid layer of the core of earth Surrounds inner core
Inner Core- Solid, dense center of our planet About 6,378 km below earth s surface 18) Corona- Outer most layer of the sun extending out to 10-12 times the diameter of the sun - Gas so thin that it s only visible during a total eclipse Chromosphere- Thin region below the Corona, only 3,000 km thick Deep red, like Corona, but only visible during total eclipse
Photosphere- Visible surface of the sun Gases are thick enough to be seen at all times Only about 600 km thick
Convective Zone- region about 200,000 km thick where gases circulate in the convection currents Hot gases rise while cooler sinks towards interior
Radiative Zone- Very dense zone about 300,000 km thick Atoms are so closely packed that is takes light millions of years to get through
Core- Center of the sun - Sun s energy is produced here - About 200,000 km in diameter - About 15,000,000 C Solar Flares- A large explosion on the Sun s atmosphere that can release as much as 6 x 1025 joules of energy Solar Prominences- Large eruptions of luminous hydrogen gas that rises thousand s of km about the Chromosphere Sun Spots- Cooler, dark spots on the sun Oceanography- the study of the ocean and its features Astronomy- The study of space and the stars, planets, other galaxies, and even new space travel Meteorology- The study of weather on the earth s atmosphere, with wind, tornados and even hurricanes Geology- The study of earth and all its features from earthquakes to volcanoes to even little cracks in the ground 1.

23) Continental Shelf- Begins at the shoreline and slopes gently towards open sea, normally reaching 200 m deep. Continental Slope- Begins at the edge of the shelf, and continues down to the flattest part of the ocean floor for about 200m to 4000m. Continental Rise- Base of the continental slope, made up of large piles of sediment, the boundary between the continental margin and the deep-ocean basin. Abyssal Plain- Broad, flat portion of the deep-ocean basin ranging from a depth of 4,000m. Mid-ocean Ridge- mountain chains formed where tectonic plates pull apart, this also creates cracks in the ocean floor called the rift zone. Seamounts- Individual Mountains of volcanic material that rise up from the earth s crust 24) Plankton- organisms that float at or near the ocean s surface, most are microscopic. Also divided into 2 sections; Zooplankton and Phytoplankton Benthos- organism that live on or at the ocean floor, which most are bottom feeders. Nekton- Free-swimming organisms of the ocean, most abundant in surface waters 25) Troposphere- the area in which we live in, containing most of the worlds life, clouds, water vapor, and weather, even most of our pollution too. Stratosphere- layer above the Troposphere, very thin air with little moisture, extremely cold, about 60 C, and also contains most of the world s ozone layer Mesosphere- the coldest layer, also containing the jet stream as well Thermosphere- the upper most layer of our atmosphere, with temperatures reaching 1,700 C 26) Radiation- The transfer of energy as electromagnetic waves. Conduction- The transfer of thermal energy from one material to another by contact. Convection- The transfer of thermal energy by the circulation or movement of a liquid or gas. 27) Cumulus Clouds- puffy white clouds that have flat bottoms, normally located in the middle of our atmosphere Stratus Clouds- Forms in layers, often cover large areas, covering the sun. normally located near earth s surface Cirrus Clouds- Thin, feathery clouds found high about earth s surface. Form mostly when winds are strong 28) Cold Fronts- A cold air mass meets and displaces the warm air mass, or pushing the warm air mass up. - Brings cooler weather and thunderstorms, heavy rain, or snow Warm Fronts- A warm air mass meets a cold mass and overtakes it. Brings drizzly weather but usually clear afterwards
Occluded Fronts- A faster moving cold air mass overtakes a slower moving warm air mass, which forces the warm air up. Brings cool temperatures and large amounts of rain
Stationary Fronts- A cold air mass meets a warm air mass and little horizontal movement Brings same weather as a warm front. Isobars- lines that connect points of equal air pressure Refracting Telescopes- Uses 2 lenses to focus the light into a focal point Reflecting Telescope- Uses 2 mirrors and a lens to focus all the light into on point Greenhouse effect- the gases in the atmosphere trap thermal energy Topographic Map- A map that shows surface features, or topography, of the Earth.
