|\ |\ |\ |\ |\
WITH ANSWERS |\
core - CORRECT ANSWERS ✔✔Center of the earth;
|\ |\ |\ |\ |\ |\ |\ |\
composed of iron and some nickel; solid inner core &
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
liquid outer core |\ |\
mantle - CORRECT ANSWERS ✔✔the layer of of earth
|\ |\ |\ |\ |\ |\ |\ |\ |\
outside the core; mostly solid and makes up about 70% of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
Earth's volume
|\ |\
crust - CORRECT ANSWERS ✔✔the rocky outer shell of the
|\ |\ |\ |\ |\ |\ |\ |\ |\
planet
|\
lithosphere - CORRECT ANSWERS ✔✔thin, upper part of |\ |\ |\ |\ |\ |\ |\ |\
the mantle and the outermost crust; the rock consists of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
cooler, brittle rock |\ |\
asthenosphere - CORRECT ANSWERS ✔✔below the |\ |\ |\ |\ |\ |\
lithosphere; contains malleable rock that can move over |\ |\ |\ |\ |\ |\ |\ |\
time
,igneous rock - CORRECT ANSWERS ✔✔molten magma
|\ |\ |\ |\ |\ |\ |\
that has cooled under Earth's surface; associated with
|\ |\ |\ |\ |\ |\ |\ |\
volcanic activity |\
sedimentary rock - CORRECT ANSWERS ✔✔created by |\ |\ |\ |\ |\ |\ |\
underwater sediments in the ocean compacted by |\ |\ |\ |\ |\ |\ |\
pressure as the sediment layer builds up|\ |\ |\ |\ |\ |\
metamorphic rock - CORRECT ANSWERS ✔✔formed when |\ |\ |\ |\ |\ |\ |\
either igneous or sedimentary rock is subject to extreme
|\ |\ |\ |\ |\ |\ |\ |\ |\
heat and pressure
|\ |\
gases in the atmosphere - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\
✔✔Nitrogen - 78% |\ |\

Argon - 0.9% |\ |\
Carbon dioxide - 0.038% |\ |\ |\
troposphere - CORRECT ANSWERS ✔✔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 ANSWERS ✔✔less dense and |\ |\ |\ |\ |\ |\ |\
temperature increases with height; absorbs much of the
|\ |\ |\ |\ |\ |\ |\ |\
ultraviolet energy from the sun|\ |\ |\ |\
mesosphere - CORRECT ANSWERS ✔✔temperature |\ |\ |\ |\ |\
decreases with height; most meteors burn up when
|\ |\ |\ |\ |\ |\ |\ |\
entering
thermosphere - CORRECT ANSWERS ✔✔extremely thin; |\ |\ |\ |\ |\ |\
an abundance of ions; temperature increases with height
|\ |\ |\ |\ |\ |\ |\
exosphere - CORRECT ANSWERS ✔✔outer most layer;
|\ |\ |\ |\ |\ |\ |\
very few particles

ozone layer - CORRECT ANSWERS ✔✔located in the lower
|\ |\ |\ |\ |\ |\ |\ |\ |\
part of the stratosphere; absorbs nearly 99% of the sun's
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ultraviolet light |\
ionosphere - CORRECT ANSWERS ✔✔Upper part of Earth's
|\ |\ |\ |\ |\ |\ |\
atmosphere
|\
-encompasses both mesosphere and thermosphere |\ |\ |\ |\
barometer - CORRECT ANSWERS ✔✔measure
|\ |\ |\ |\ |\
atmospheric pressure |\
, aurora/australis borealis - CORRECT ANSWERS ✔✔natural |\ |\ |\ |\ |\ |\
atmospheric light displays; result of Earth's photons |\ |\ |\ |\ |\ |\ |\
emitting light as they collide with solar wind particles and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
regain electrons
|\
hydrology - CORRECT ANSWERS ✔✔The study of all water
|\ |\ |\ |\ |\ |\ |\ |\
on Earth, including its movement and distribution.
|\ |\ |\ |\ |\ |\ |\
hydrosphere - CORRECT ANSWERS ✔✔all the water on |\ |\ |\ |\ |\ |\ |\ |\
Earth's surface, groundwater, and water in the
|\ |\ |\ |\ |\ |\ |\
atmosphere
waves - CORRECT ANSWERS ✔✔formed by winds on the
|\ |\ |\ |\ |\ |\ |\ |\ |\
surface of bodies of water
|\ |\ |\ |\
tectonic plates - CORRECT ANSWERS ✔✔plates in the
|\ |\ |\ |\ |\ |\ |\ |\
lithosphere that shift causing transformations to Earth's
|\ |\ |\ |\ |\ |\ |\
landscape
continental drift - CORRECT ANSWERS ✔✔the gradual |\ |\ |\ |\ |\ |\ |\
movement of the continents across the earth's surface
|\ |\ |\ |\ |\ |\ |\
Pangaea - CORRECT ANSWERS ✔✔supercontinent
