The (a) keeps the troposphere warm enough to sutain life on Earth.
An ecosystem has an ecological efficiency of 10 percent. If the producer level contains 60,000 kilocalories of energy, how much energy does the tertiary consumer level contain?
600 kilocalories
60 kilocalories
6000 kilocalories
60000 kilocalories
If Northern glaciers melt at an accelerated rate, which consequence is most likely to occur?
Water in the Northern Hemisphere would become warmer due to latent heat, preventing it from sinking.
Water in the Northern Hemisphere would become less salty, preventing it from sinking.
Water in the Northern Hemisphere would sink at a faster rate, speeding up global ocean currents.
Water in the Northern Hemisphere would become more salty, causing it to sink to a lower depth.
Which of the following would reduce global greenhouse emissions?
Switching from hydroelectric power generation to power generation using natural gas as the primary fuel
Increasing the use of automobiles
Decreasing the number of nuclear power plants
Replacing coal-burning power plants with wind farms
The relationship between a mosquito and human is an example of (a) .
The relationship between a clownfish and anemone describe a what type of relationship.
Hint: The clownfish uses the anemone for protection and the anemone is not affected by the clownfish.
(a)
CFCs and halons are examples of __________________________ chemicals because they do not exist in nature.
Anthropogenic
Naturalistic

The irregular movements in the tilt of the Earth's axis of rotation
The constant tilt of the Earth's rotational axis with respect to the plane of its orbit around Sun
The regular changes in the relative positions of the Earth, its Moon, and the Sun
Rank the articles in order of increasing size

The graph below represents the composition of Earth’s atmosphere.
Which correctly identifies the location of each gas?
Region 1 = carbon dioxide, Region 2 = oxygen, Region 3 = nitrogen
Region 1 = nitrogen, Region 2 = carbon dioxide, Region 3 = oxygen
Region 1 = nitrogen, Region 2 = oxygen, Region 3 = carbon dioxide
Region 1 = oxygen, Region 2 = nitrogen, Region 3 = carbon dioxide
(a) occurs as the natural circulation of fluid caused by the tendency of warm fluids to rise and cool fluids to sink.
Which layer of the Earth’s atmosphere contains the ozone layer?
exosphere
stratosphere
troposphere
mesosphere
Which correctly identifies the layers of the atmosphere at the lowest and highest altitude?
The troposphere is located at the lowest altitude, while the thermosphere is located at the highest altitude.
The stratosphere is located at the lowest altitude, while the troposphere is located at the highest altitude.
The troposphere is located at the lowest altitude, while the exosphere is located at the highest altitude.
Which of the following is the best description of a region’s climate?
The average high temperature of a region
The average temperature and rainfall over a period of 1-2 years
The average temperature and precipitation over several decades
The amount of rainfall that an area receives over a period of 1 year
Which best summarizes the relationship between movement of water and particle size?
As the size of the particles increases, the movement of water through the soil happens at a faster rate.
As the size of the particles decreases, the movement of water through the soil happens at a faster rate.
Soils with large percentages of clay tend to allow water to move through them quickly.
Particle size only affects the movement of solid particles and living organisms through the soil.
Earth’s climate ___________.
Has been stable over the history of the planet
Has been documented to have changed once due to the evolution of green photosynthesizing plants
History is undeterminable because there is no method of studying climatic history of the planet
Is changing as a result of natural but mainly human processes

upwellings of nutrient rich water are increased
the trade winds are weaken or reverse in direction across the tropical Pacific Ocean
it has negatively affected the fishing industry in Peru
The discovery of the (a) was a blessing to the farmers who were in danger of losing their crops because of the drought.
Exposure to (a) can cause many human health effects including more sever sun burns, skin cancer, and eye cataracts.
The earthquake was caused by (a) at a convergent plate boundary and triggered a series of earthquakes that lead to tsunamis along the coasts.
