Scientists have been monitoring CO2 in the atmosphere from Mauna Loa in Hawaii since 1958. Which of the following units is used by scientists to measure CO2 in the atmosphere?

• Dobson units

• Percent saturation

• Parts per million

• pH

A student is setting up a model to study the carbon cycle and natural sources of carbon dioxide. They create a microenvironment that contains soil, leaf debris, an earthworm, heterotrophic bacteria, and a sun lamp. What natural source of carbon dioxide and major metabolic process was left out of the model?

• There is no representation of decomposition in the model environment.

• There is no representation of cellular respiration in the model environment.

• There is no representation of photosynthesis in the model environment.

• There is no representation of ingestion in the model environment.

If the air layers in the diagram were relabeled to illustrate normal atmospheric conditions, the correct labeling from the air layer closest to the Earth’s surface to the one farthest from the Earth’s surface would be:

• cool air, cooler air, warm air

• warm air, cool air, cooler air

• cooler air, warm air, cool air

• cooler air, cool air, warm air

Based on the layers in the diagram, which of the following best explains why a thermal inversion tends to concentrate pollutants in the air layer closest to the Earth’s surface?

• The air layer that is the second closest to the Earth’s surface is less dense than the layer above it.

• The inversion layer is warmer than the air layer that is farthest from the Earth’s surface.

• The air layer closest to the Earth’s surface is denser than the layer above it.

• The air layer that is farthest from the Earth’s surface contains the coolest air.

The data that were used to create this graph were collected in the winter. Which of the following best describes how the graph would be different if the data were collected in the middle of the summer?

• The peaks for every data line would be at a lower concentration.

• Concentrations for component C would be higher throughout the graph.

• Concentrations for all the data lines would be the horizontal throughout the day.

• Components A, B, and D would peak in the afternoon instead of in the morning.
