Final exam

Topographic Map shows what topographic maps characterize and show areas of the Earth's shape by displaying contour lines and symbols.
3 types of landforms Mountain, hill and plateau
Rocky mountains- high or low, relief and elevation- Both high relief and high elevation
Contour interval the interval between contour lines on a map, or the altitude the interval represents
Streak a long thin stripe or band that is a different color from its background or surroundings
gemstone a mineral or stone suitable for use in jewelry after cutting and polishing
crystal a solid containing an internal pattern of atoms, molecules, or ions that is regular, repeated, and geometrically arranged
alloy a substance that is a mixture of two or more metals, or of a metal with a nonmetallic material
cleavage the splitting of minerals or rocks along natural planes of weakness determined by their internal crystal lattice.
Compound a substance formed by the chemical combination of elements in fixed proportions
Size of crystals magma cooling fast or slow
Hardest mineral diamond
the 5 characteristics a substance mush have to be a mineral Naturally occurring, solid,forms by inorganic processes, crystal structure, definite chemical composition
Igneous rocks rocks formed under conditions of intense heat or produced by solidification of volcanic magma on or below the earth's surface
Most abundant intrusive rock granite
Geologist describe rock's texture coarse or fine grained
Metamorphic rock relating to or involving a change in physical form appearence or character
Rock cycle the phases a rock goes through
Order of Earth's layer inner core, outer core, mantle, and crust
Alfred Wegner's hupothesis of continental drift There was once a super contitnent called pangea
Subduction to be carried under the edge of an adjoining continental or oceanic plate causing tension int he Earth's crust that can produce earthquakes or volcanic eruptions
Theory of Plate tectonics The continents are always moving
Where do you find most mid-ocean ridges in the Pacific Ocean
P wave a type of seismic wave that compresses and expands the ground
S wave a type of seismic wave in which the shaking is perpendicular to the direction of the wave
Seismograph an instrument that detects the presence of an earthquake and measures and records its magnitude
stress a force that acts on rock to change its shape or volume
Where do volcanic belts form Arund earth's boundarys
Viscosity of magma depends on what 2 things Temperature and pressure
Cinder cone volcano material that build aroung the vent in a steep cone shaped hill or small mountain
Compsoite volcano are tall cone-shaped mountains in which layers of lava alternate with layer of ash
Shield volcanos such lava flows slowly build a wide gently sloping mountain
Lava plateaus The thin runny lava floods the area and travels far before cooling and solidifying, after millions of years repeated floods of lava can form high level plateaus
Active volcano can erupt at any time
extinct never will erupt again
dormant volcano sleeping but can become active
concentration the removal of water from something usually a liquid to make it thicker or stronger
potential energy the energy that a body or system has stored because of its position in a electrical magnetic or gravitational field, or because of its configuration
kinetic energy the energy that a body or systen has becaus of its motion
hardness the test to tell you how hard a rock is
ph scale measures how acidic or basic a substance is
Steps in water treatment screening,pumping,and aerating
Salinity of water how much salt is in the water
What happens to temperature as you descend through the water column it gets colder and colder
wavelength in physics the distance between two points on adjacent waves that have the same phase
trough narrow channel, gully, or gutter in which liquid passes especially one under the eaves of a roof for catching rainwater
neap tide , a tide that shows the least range between high and low and occurs twice a month between the first and third quarters of the moon
spring tide a tide that occurs near the time of the new moon and full moon and has a greater than adverage ranger
longshore drift the gradual movement of material along a coast caused by the action of waves having a component of motion parallel to the coaste
size of wave is affected by 3 thing wind,tempurature,and moon cycle
Wave near shore when a wave gets o shore it reseeds and then comes back bigger
What need for algae to grow in thee ocean water shallow water and a lot of sun
Trench a long narrow valley on an ocean or seafloor
Benthos the animals and plants that live on or in the sediment at the bottom of a sea, lake, or deep river
Nekton An orgamism such as a fish that lives in water and can actively swim against currents as opposed to microorganisms that are simply carried along
Intertidal zone occurring within or forming the area between the high and low tide levels in a coastal zone
Hydrothermanl vent small hill like object that shoot out super hot gasses located at the bottom of the ocean nearing a volcanoe
kelp forests grow deep under the wate and grow up towards the sun.
Characteristics of twilight and midnight zone the twilight zone has little light but the midnight zone has no light at all.
fluorescence the emission of electromanetic radiation especially light by an object or substance exposed to radiation or bombarding particles
bioluminescence the generaltion and emission of light by organisms such as fireflies some bacteria and fungi and many animals that live in the ocean
chemiluminescence emission of light as a result of a chemical reaction without producing heat
Order of planets Mercury, Venus, Earth, Mars, Jupitor, Saturn, Uranus, Neptune and Pluto
CORE The central or most important part of the sun
Radiation zone energy emitted from a source in the form of rays or waves
convection zone a layer of a star across which energy is transported outward mainly by convection currents
Sunspot any of the relatively cool dark patches that appear in cycles on the Sun's surface into interplanetary space
Solar flares a brief sudden eruption of high energy hydrogen gas from the surface of the sun associated with sunspots
solar winds the flow of high-speed ionized particles from the Sun's surface into interplanetary space
meteors a mass of rock from space that burns up after entering Earth's atmosphere
Meteoroids a mass of rock in space often a remnant of a comet that becomes a meteor when it enters the Earth's atmosphere and a meteorite when it falls to Earth
Meteorites a piece of rock that has reached Earth from outer space
Comet an astronomical object that is composed of a mass of ice and dust and has a long luminous tail produce by vaporization when its orbit passes clise to the sun.
Stars are made of what and array of different gasses
Spiral galaxy a galaxy consisting of an older central nucleus of stars from which extend two spiral arms of gas dust and newer stars
Barrel spiral galaxies close to a spiral but this one has a ling line through it
Elliptical galaxy a galaxy with an overall elliptical or spherical shape and no arms or internal structure
Irregular galaxy a galaxy that has none of the same characteristics of other galaxies
