what is Atmospheric layer
The atmosphere is comprised of layers based on temperature. These
layers are the troposphere, stratosphere, mesosphere and thermosphere.
what is Thermosphere
fourth layer; coldest layer in the Earth's atmosphere directly above the
mesosphere and below the exosphere
what is Weather front
a boundary in between two masses of air of different densities, and is the
main cause of significant weather.
what is evaporation
water getting heated up
is gold a rock or a mineral
it is a mineral
what is Ozone layer
region of Earth's stratosphere that absorbs most of the Sun's ultraviolet
radiation.
what is Global wind
winds that are created by both the spin of the Earth (Coriolis effect) and the
differences in temperature between the equator and the polar areas
what is tornado
violently spinning, funnel-shaped columns of air that stretch from the dark
thunderclouds they form in all the way to the ground
what is condensation
water vapor forming clouds
what is the three types of rocks
sedimentary, metamorphic,and igneous
what is Troposphere
: lowest layer of the atmosphere of Earth
what is local wind
winds that are generated by changes in air pressure and temperatures locally
what is Hurricane
strong storms that start in the ocean and have winds of at least 74 miles an
hour
what is transportation
getting water from plants
how is metamorphic rock formed
when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors.
what is Mesosphere
third layer; coldest layer of the atmosphere, directly above the
stratosphere and directly below the thermosphere
what is Coriolis effect
a force that affects a moving object over a rotating body
what is thunderstorm
a storm with lightning and thunder. Its produced by a cumulonimbus
cloud, usually producing gusty winds, heavy rain and sometimes hail
what is precipitation
when clouds cant hold no more water it rains which causes precipitation
how is sedimentary rock formed
from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth's surface
what is Stratosphere
second layer; layer of Earth's atmosphere lying between the troposphere
and the mesosphere where planes fly
what is air mass
a body of air extending hundreds or thousands of miles sideways and
sometimes as high as the stratosphere
DOUBLE POINT: in what layer does meteors heat up in
exosphere
what is sublimation
water that
how is igneous rock formed
when hot, molten rock crystallizes and solidifies
