5905 Science Praxis EXAM fully solved & updated (latest version verified for
accuracy) (Questions + Answers) Solved 100- Correct!!
core - (ANSWER)Center of the earth; composed of iron and some nickel; solid inner core & liquid outer
core
mantle - (ANSWER)the layer of of earth outside the core; mostly solid and makes up about 70% of
Earth's volume
crust - (ANSWER)the rocky outer shell of the planet
lithosphere - (ANSWER)thin, upper part of the mantle and the outermost crust; the rock consists of
cooler, brittle rock
asthenosphere - (ANSWER)below the lithosphere; contains malleable rock that can move over time
igneous rock - (ANSWER)molten magma that has cooled under Earth's surface; associated with volcanic
activity
sedimentary rock - (ANSWER)created by underwater sediments in the ocean compacted by pressure as
the sediment layer builds up
metamorphic rock - (ANSWER)formed when either igneous or sedimentary rock is subject to extreme
heat and pressure
gases in the atmosphere - (ANSWER)Nitrogen - 78%
Oxygen - 21%
Argon - 0.9%
Carbon dioxide - 0.038%
,5905 Science Praxis EXAM fully solved & updated (latest version verified for
accuracy) (Questions + Answers) Solved 100- Correct!!
troposphere - (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 - (ANSWER)less dense and temperature increases with height; absorbs much of the
ultraviolet energy from the sun
mesosphere - (ANSWER)temperature decreases with height; most meteors burn up when entering
thermosphere - (ANSWER)extremely thin; an abundance of ions; temperature increases with height
exosphere - (ANSWER)outer most layer; very few particles
ozone layer - (ANSWER)located in the lower part of the stratosphere; absorbs nearly 99% of the sun's
ultraviolet light
ionosphere - (ANSWER)Upper part of Earth's atmosphere
-encompasses both mesosphere and thermosphere
barometer - (ANSWER)measure atmospheric pressure
aurora/australis borealis - (ANSWER)natural atmospheric light displays; result of Earth's photons
emitting light as they collide with solar wind particles and regain electrons
hydrology - (ANSWER)The study of all water on Earth, including its movement and distribution.

accuracy) (Questions + Answers) Solved 100- Correct!!
hydrosphere - (ANSWER)all the water on Earth's surface, groundwater, and water in the atmosphere
waves - (ANSWER)formed by winds on the surface of bodies of water
tectonic plates - (ANSWER)plates in the lithosphere that shift causing transformations to Earth's
landscape
continental drift - (ANSWER)the gradual movement of the continents across the earth's surface
Pangaea - (ANSWER)supercontinent
earthquakes - (ANSWER)destructive releases of energy in Earth's crust caused by seismic waves
fault - (ANSWER)a fracture between two plates
epicenter - (ANSWER)The location on the surface directly above the focus of the earthquake
Seismometer (Seismograph) - (ANSWER)measures and records earthquakes
tsunami - (ANSWER)a series of waves that have the potential to devastate coastal regions with massive
volumes of water and energy
volcanoes - (ANSWER)an opening in the Earth's crust through which molten lava, ash, and gases are
ejected; caused by the movement of tectonic plates
