Climate Flashcards
Weather
Local conditions of temperature, air pressure, cloud cover, precipitation, and humidity that occur at a place at a particular time
Climate
Average weather conditions that occur in a region over a long period of time
Open System
Both energy and matter are exchanged between the system and the surroundings
Closed System
Energy is exchanged between the system and the surroundings, but matter is not
Isolated System
Neither energy nor matter are exchanged between the system and the surroundings
What type of system is the Earth
Earth is a closes system because energy flows through it, but matter must be recycled
Biosphere
A thin layer of air, land, and water on or near the Earth’s surface that supports life
Biosphere - Atmosphere
Air composed of a mixture of different gasses
Biosphere - Lithosphere
Land that extends about 100km below teh surface
Biosphere - Hydrosphere
All of the water on earth
- Surface and groundwater
- Clouds
- Cryosphere (Frozen Water)
Solar Energy
Form of radiant energy. All energy on earth comes from the sun as solar energy
Angle of inclination
The angle the Earth tilts from perpendicular to its orbit (~23.5°)
Solstice
Two points in Earth’s orbit when the poles are the most tilted toward or away from the sun
- December 21- Shortest Day
- June 21 - Longest Day
Equinox
Two points in the Earth’s orbit when the number of daylight hours is equal to number of hours of night
- March 21
- September 22
______ ____ causes season variation in temperature and daylight hours at different latitudes
Earth’s tilt
- Summer in Canada - North Pole tilted toward the Sun (March to September)
- Winter in Canada - North Pole tilted away from the Sun (September to March)
Angle of Incidence
The angle between the incoming solar radiation and the line perpendicular to the Earth’s surface
Climate Zones
A result of Earth’s curved shape which causes a variation in the intensity of light at different latitudes
Climate Zones - Tropical (0° - 23.5°)
Nearly perpendicular angle of incidence throughout the year, warm temperatures year-round
