This boundary exists at the San Andreas fault.
What is a transform boundary?
100
The constant tilt of the Earth's rotational axis as it orbits around the sun causes these.
What are seasons?
100
This is the direction in which the trade winds deflect from 0 degree to 30 degree latitude
west to east
100
Why are there various temperatures among the earth's surface
This is created by the uneven solar radiation from the Earth's tilt.

How will El Niño impact anchovy fishing in South America
Reduce it because lack of upwelling
200
This type of boundary exists at the Mid-Atlantic Ridge and increases the amount of Earth's crust.
What is a divergent boundary?
200
This is the layer of the atmosphere in which the vast majority of ozone found.
What is the stratosphere?
200
These are the percentages of N2, O2, and CO2 in the troposphere.
What are 78, 21, and .04?
200
This global area would receive 24 hours of daylight on 12/21.
What is E?
200
List two negative environmental impacts that can occur from an area that has a decrease in precipitation
drought, less surface water, aquifers not recharged, organisms can die / dry out, increased wildfires, desertification

What causes an earthquake? What boundary/boundaries are earthquakes most likely to result from
Overcoming stress in a locked fault, occurs at transform and convergent
300
This layer contains decomposing plant and animal matter.
What is A?
300
If a developer removes large trees, what would happen to the soil in the area?
What is... increased erosion /increase in temperature because lack of shade
300
Insulation is dependent on what two factors
1. Angle: how directly rays strike earth’s surface
2. The amount of atmosphere sun’s rays pass through

El Nino and La Nina occur in the ... (choose one)
East Pacific
Gulf of Mexico
Atlantic
Indian Ocean
What is the east Pacific?
400
How did the snow this weekend affect the albedo effect of the grounds?
Increased resulting in cooler temperatures
400
This layer has little organic matter and accumulates soluble materials from other layers.
What is C? the subsoil layer
400
This is the reason why rainforests are near the equator but deserts are at 30 degrees above and below it.
What are descending dry air currents? Hadley cell resulting in warm air rising at the equator as warm air rises precipitation occurs then cool dry air falls at 30 latitude
400
The term for an area having little rainfall because it is sheltered from prevailing rain-bearing winds by a range of hills.
What is a rain shadow?
400
Give one environmental effect from the increase in normal rainfall and a decrease in normal rainfall
increase: flooding, soil erosion, leaching of nutrients from soil
decrease: increase competition for resources, reduced agriculture, increase in forest fires, drought/water shortages, species die off
500
Explain why having clay soil is either good or bad for septic tanks which need to drain waste into the soil.
Low permeability resulting in drainage issues, systems failures, etc.
500
The layer of Earth's atmosphere with the highest pressure; weather occurs here.
What is the troposhere?

There are concerns about the health of streams in a watershed in which there is road repair work in an area with many dairy farms. Of the following, which would be the best option for preventing sediment runoff into streams?
Have construction crews steepen the slopes of the valleys of streams near roadwork zones.
Maintain zones of grass at least 100m wide on the sides of streams in the area.
Construct at least one dam on a stream in the watershed to improve flood control.
Shift from dairy farming to corn planted in agricultural fields located within 100m of streams.
What is maintain zones of grass..
