5905 Science Praxis
core - CORRECT ANSWER-Center of the earth; composed of iron and some
nickel; solid inner core & liquid outer core
mantle - CORRECT ANSWER-the layer of of earth outside the core; mostly solid
and makes up about 70% of Earth's volume
crust - CORRECT ANSWER-the rocky outer shell of the planet
lithosphere - CORRECT ANSWER-thin, upper part of the mantle and the
outermost crust; the rock consists of cooler, brittle rock
asthenosphere - CORRECT ANSWER-below the lithosphere; contains malleable
rock that can move over time
igneous rock - CORRECT ANSWER-molten magma that has cooled under
Earth's surface; associated with volcanic activity
sedimentary rock - CORRECT ANSWER-created by underwater sediments in the
ocean compacted by pressure as the sediment layer builds up
metamorphic rock - CORRECT ANSWER-formed when either igneous or
sedimentary rock is subject to extreme heat and pressure
gases in the atmosphere - CORRECT ANSWER-Nitrogen - 78%
Oxygen - 21%
Argon - 0.9%
Carbon dioxide - 0.038%
troposphere - CORRECT ANSWER-near the surface of Earth; where weather
takes place and the location of almost all clouds; pressure and temperature
decrease with height in this layer
stratosphere - CORRECT ANSWER-less dense and temperature increases with
height; absorbs much of the ultraviolet energy from the sun
,mesosphere - CORRECT ANSWER-temperature decreases with height; most
meteors burn up when entering
thermosphere - CORRECT ANSWER-extremely thin; an abundance of ions;
temperature increases with height
exosphere - CORRECT ANSWER-outer most layer; very few particles
ozone layer - CORRECT ANSWER-located in the lower part of the stratosphere;
absorbs nearly 99% of the sun's ultraviolet light
ionosphere - CORRECT ANSWER-Upper part of Earth's atmosphere
-encompasses both mesosphere and thermosphere
aurora/australis borealis - CORRECT ANSWER-natural atmospheric light
displays; result of Earth's photons emitting light as they collide with solar wind
particles and regain electrons
hydrology - CORRECT ANSWER-The study of all water on Earth, including its
movement and distribution.
hydrosphere - CORRECT ANSWER-all the water on Earth's surface,
groundwater, and water in the atmosphere
waves - CORRECT ANSWER-formed by winds on the surface of bodies of water
tectonic plates - CORRECT ANSWER-plates in the lithosphere that shift causing
transformations to Earth's landscape
continental drift - CORRECT ANSWER-the gradual movement of the continents
across the earth's surface
Pangaea - CORRECT ANSWER-supercontinent
, earthquakes - CORRECT ANSWER-destructive releases of energy in Earth's
crust caused by seismic waves
fault - CORRECT ANSWER-a fracture between two plates
epicenter - CORRECT ANSWER-The location on the surface directly above the
focus of the earthquake
Seismometer (Seismograph) - CORRECT ANSWER-measures and records
earthquakes
tsunami - CORRECT ANSWER-a series of waves that have the potential to
devastate coastal regions with massive volumes of water and energy
volcanoes - CORRECT ANSWER-an opening in the Earth's crust through which
molten lava, ash, and gases are ejected; caused by the movement of tectonic
plates
mountain ranges - CORRECT ANSWER-plates consist of continental and
oceanic crust; as the plates collide, they push land masses together which can
cause the surface to be forced upwards
ocean trenches - CORRECT ANSWER-due to the sliding of one tectonic plate
underneath another as they move towards each other, or subduction
Ring of Fire - CORRECT ANSWER-home to about 90% of the world's
earthquakes
mineral - CORRECT ANSWER-a solid substance that has a specific chemical
composition and a crystal structure
rocks - CORRECT ANSWER-solid substances that may be made up of different
types of minerals
erosion - CORRECT ANSWER-the process that changes the surface of Earth by
wearing away rock and carrying away soil through agents of current
