Weather
Large body of circulating air with high pressure at its center. Brings clear skies and fair weather
High pressure system
Cold air rushes under the warm air forcing it to rise. Leads to rainy weather.
Cold fronts
What are the three types of plate boundaries?
Convergent
Divergent
Transform
Mountain ranges are formed by what type of plate boundary?
Convergent
What defines a population?
A population is all the organisms of the same species that live in the same area at the same time
True or false: Cool air can hold the greater amount of water vapor
False
This is a large body of air with relatively similar temperature and humidity
Air mass
How does sea floor spreading show Earth's magnetic fields through time?
How are ocean trenches formed?
Subduction of one plate under another at a convergent boundary
Name two ways a population in an area can decrease
If not as many members of the species survive to adulthood
If part of the population moves to a different area
What are the three steps of the water cycle?
What is water's state of matter when you see clouds?
Precipitation, Condensation, Evaporation
Condensed vapor into liquid water or ice crystals
This type of pressure causes clouds and rain or storms.
Low pressure system
What type of movement occurs at a divergent boundary?
Divergent plates move away from each other in opposite directions
How are Mid-ocean ridges formed?
Tension from divergent boundaries
Competition is ________
Competition is caused by______
demand for resources such as food, water, and shelter, in short supply in a community
Limiting factors
This is caused by the weight of the air above an area
Air pressure
What is the symbol for a cold front?
Blue triangles
What happens when a continent sits on plates that are diverging?
Eventually the continent will be seperpated
What forms a continental rift?
Tension at a divergent boundary within a continent (East African Rift)
Explain how competition could limit the size of a bird population
Birds that cannot find a place to nest due to competition for nesting space will not be able to produce offspring They will not be able to lay eggs and add young to the population
This is the color and symbol for Low Pressure.
What is L (red).
What is the symbol for a occluded front?
Alternating semi-circles and triangles on the same side of the front line
What are the three forces that are at work at plate boundaries?
Compression
Tension
Shear stress
What are two landforms created by shear stress?
Transform faults
Fault zones
Summarize how biotic potential and competition for biotic and abiotic factors are connected.
Biotic potential is the potential growth of a population if it could grow in perfect conditions with no limiting factors. No population has ever reached its biotic potential because limiting factors exist. Populations must compete for biotic and abiotic factors to survive. Increased competition limits biotic potential.
