|
Weather
|
the state of the atmosphere at a place and time as regards heat, cloudiness, dryness, sunshine, wind, rain, etc.
|
|
|
energy source
|
source of energy.
|
|
|
mercurial barometer
|
barometer filled with mercury. mercury goes higher when the atmospheric is higher
|
|
|
tropopause
|
the boundary between the troposphere and the stratosphere
|
|
|
mesosphere
|
second highest layer of the atmosphere
|
|
|
ionosphere
|
part of the thermosphere, where the atmosphere is ionized by solar radiation
|
|
|
nitrogen cycle
|
The process of which nitrogen cycles through the Earth. it goes from the atmosphere to plants and animals and back up.
|
|
|
Vernal/Autumnal equinox
|
The point where the sun is directly above the equator.
|
|
|
Summer/Winter solstice
|
The point where the sun's zenith is northernmost or southernmost
|
|
|
Arctic circle
|
It has a 24-hour day during our summer, and a 24-hour night during our winter
|
|
|
Direct Solar rays
|
When the says rays are vertical to Earth, and Earth gets the most energy possible.
|
|
|
terminator
|
the dividing line between the light and dark part of a planetary body.
|
|
|
insolation
|
measure of solar radiation energy received on a given surface area in a given time
|
|
|
barometer
|
a device used to measure air pressure.
|
|
|
atmospheric pressure
|
the force per unit area exerted against a surface from the atmosphere
|
|
|
stratosphere
|
the third highest layer in the atmosphere. The ozone layer is here
|
|
|
mesopause
|
the boundary between the Thermosphere and Mesosphere
|
|
|
ozone
|
a pale blue gas that occurs in the upper atmosphere and ground level. This is a polutent to Earth on the surface but is good in the atmosphere
|
|
|
aphelion
|
the point where the earth is farthest to the sun
|
|
|
perihelion
|
the point where the Earth is farthest from the sun
|
|
|
axis of rotation
|
an imaginary line going through the north and south pole, and is what the Earth rotates on.
|
|
|
Tropic of Cancer
|
23.5 degrees North. The Northernmost latitude line in which the sun can appear directly overhead at noon.
|
|
|
Antarctic Circle
|
66.5 degrees South. During our winter, it has 24 hours of daylight, and during our summer it has 24 hours of night.
|
|
|
indirect solar rays
|
because of the tilt, the rays are not vertical to earth, and not all of the energy is given on a specific place
|
|
|
exoplanet
|
a planet beyond our solar system, orbiting a star other than our sun
|
|
|
radiation
|
the process in which energy given off by one body travels through through space, ultimately to be absorbed another body
|
|
|
aneroid barometer
|
a circular object in which bulges in the center tell if the atmospheric pressure is higher or lower.
|
|
|
troposphere
|
the lowest layer of the atmosphere. 75% of the atmospheres mass is here and the only weather is here
|
|
|
stratopause
|
the boundary between the stratosphere and mesosphere.
|
|
|
thermosphere
|
the highest layer of the earth's atmosphere. The ionosphere is here
|
|
|
carbon cycle
|
the cycle in which carbon goes through the biosphere, geosphere, the hydrosphere, and the atmosphere. This cycles carbon through air, water, ground, and plants.
|
|
|
apogee
|
the point where the moon is farthest away from Earth, in its rotation
|
|
|
perigee
|
the point where the moon is closest to Earth in its rotation
|
|
|
equator
|
a line going through the earth that is perpindicular to the axis of rotation. it divides the northern hemisphere and southern hemisphere
|
|
|
tropic of capricorn
|
23.5 S. This is the farthest point south where the sun can appear highest overhead at noon in the southern hemisphere.
|
|
|
zenith
|
the highest point reached by a celestial or other object
|
