◉ Inner Planets. Answer: Mercury, Venus, Earth and Mars.
◉ Outer Planets. Answer: Jupiter, Saturn, Uranus and Neptune. Much
larger than the inner planets and have thick gaseous atmospheres.
Called Gas Giants.
◉ Lithosphere. Answer: Earth's rocky, outer surface made of the
crust and upper mantle.
◉ Igneous Rock. Answer: rocks formed by the cooling of molten rock
(either magma or lava). ie: granite.
◉ Sedimentary Rock. Answer: form when particles of other rocks or
the remains of animals/plants are cemented together. ie: flint and
sandstone.
◉ Metamorphic Rock. Answer: rock that forms from an existing rock
that is changed by heat, pressure, or chemical reactions. This
happens deep in the earth. ie: slate and marble.
,◉ Minerals. Answer: must be naturally occurring, inorganic (cannot
form from material that was once living), solid, crystal structure
(pattern that repeats), and definite chemical composition (must
always contain a certain element).
◉ Hydrosphere. Answer: all of the water on earth.
◉ Steps in the Water Cycle. Answer: 1. Evaporation 2. Condensation
(forms clouds) 3. Precipitation
◉ Water Distribution. Answer: three-fourths of the world is covered
by water with 97% of this water found in oceans. The remaining 3%
is freshwater.
◉ Atmosphere. Answer: a mixture of gases that surrounds a planet
or moon. Earth's atmosphere is made up of 78% nitrogen, 21%
oxygen and 1% other gases.
◉ Troposphere. Answer: the layer of the atmosphere that is closet to
earth. It's the smallest layer but contains almost all the mass. Where
weather occurs.
◉ Stratosphere. Answer: second layer of the atmosphere and
contains the ozone layer. Upper section is warmer than the lower
section of the stratosphere.
, ◉ Mesosphere. Answer: 3rd layer of the atmosphere. Protects earth
from meteoroids.
◉ Thermosphere. Answer: the outermost layer of Earth's
atmosphere. Receives the most direct solar rays.
◉ Occluded Front. Answer: a front where a warm air mass is caught
between two colder air masses and brings cool temperatures and
large amounts of rain and snow.
◉ Cumulonimbus Clouds. Answer: where thunderstorms are
formed.
◉ Sling Psychomotor. Answer: measures amount of relative
humidity.
◉ Barometer. Answer: an instrument used to measure atmospheric
pressure.
◉ Anemometer. Answer: measures wind speed.
◉ Wind Vane. Answer: measures wind direction.
