Earth Science EOC Flashcards
Front symbols
Warm front – line with red half circles on top of it
Cold front – line with blue triangles on top of it
Stationary front – line with blue triangles on top of it and red half circles under it
Occluded front – line with purple triangles and purple half circles on top of it
What are the names and events in each layer?
Trophosphere – live in Stratosphere – Ozone Mesosphere – meteorites burn up Thermosphere – ionosphere Exosphere – outerspace
What is the major greenhouse gas?
Carbon dioxide (CO2)
What are air masses?
Large bodies of air
What are the stages of the water cycle
Condensation precipitation runoff percolation collection groundwater transportation evaporation
What are the factors that cause climate change?
Greenhouse effect
Global warming
What are the types of fronts?
Warm front
occluded front
cold front
stationary front
Weather brought with each type of front
Warm front – warmer temps, humid, light precipitation
Cold front – possible thunderstorms, frequent precipitation, cooler temperatures
Stationary front – cloudy, many days same weather, light showers
Occluded front – warm air trapped, heavy precipitation, temperatures drop
What is the cause of the wind?
The change in air pressure
High VS low-pressure systems
Low air pressure rises - stormy weather
High air pressure sinks - clear skies
effects of climate change
– Global warming – melting ice glaciers – warmer climate – evaporation of water – more natural disasters – forest fires
What are the factors that affect climate?
Latitude, elevation, the sun, precipitation, wind and water currents
What is the rainshadow effect?
1) Water evaporates
2) Wind carries most moist air inland. 3) Air reaches mountains and it rises
4) As it cools cold air condenses causing rain
5) Rain falls on Windward side of the mountain
6) Air reaches other side it sinks and
warms
7) The warm air produces rain shadow
What is the greenhouse effect?
The natural warming of both regions of Earth’s atmosphere from solar radiation being absorbed and emitted
What are the climate zones?
Maritime tropical – moist and warm Continental tropical – dry and warm Continental polar – dry and cold Maritime polar – moist and cold
What is the function of the ozone layer?
Protects us from the sun
How are the layers of the atmosphere classified?
According to the changes in the temperatures
Direction of fronts?
Where it points to
El Niño VS La Niña
El Niño - warm water
- lots of rain
- air circulates
La Niña - extreme cold temps
- trade winds blow
- intense precip
The cause of day and night
Earth rotates on its axis
Causes of the phases of the moon
Position in relation to the sun and Earth
Positioning of Sun Earth Moon during solar and lunar eclipses
Solar – Moon moves directly between sun and earth - casts shadow over part of Earth
Lunar – Earth’s shadow falls on moon
What is nuclear fusion?
The process that gives stars their energy
What is our suns fate as a star
Black dwarf
What are the dimmest group of stars?
Supergiants
What is the group of stars our sun is in
Main sequence
What is the coolest group of stars
Giants
What is the hottest group of stars
white dwarfs
What is the order of planets from the sun
Mercury Venus Earth Mars Jupiter Saturn Uranus Neptune Pluto
What is the composition of the planets
The first four - sold
Last four – gaseous
What is the big bang theory
How the universe evolved
What is the red shift of galaxies
If a star is moving towards earth very fast it is blueshift
If a star is moving away from earth very fast it is a red shift
