Recent climate data suggests a global warming trend. Disruption of which natural cycle most likely contributes to this temperature increase?

Which is the correct order of the layers (beginning at the Earth’s surface)?

Which components of the Earth’s systems are most correctly matched with their related topics?

A student made a model of the Earth and its atmosphere by covering a box with plastic wrap and placing thermometers inside and outside of the box. A heat lamp was shined on the box. The temperature inside the box increased at a faster rate than the outside temperature. This model best represents —

Currents carrying water past the continental shelves influence climate patterns. Currents such as the Gulf Stream in the Northern Hemisphere and the Brazilian Current in the Southern Hemisphere continually transport water heated by solar radiation from the equator toward the poles. Compared to inland areas at the same latitude, the coastal areas affected by these currents will —

Deep water ocean currents, sometimes called “conveyer belt currents,” flow as warm waters from the Gulfstream lose thermal energy, decrease in density, and sink in the Northern Atlantic. The waters then flow southward and eventually into the Pacific where they are heated again and rise. Energy flows through this system due to —

Farmers decide to stop growing legume crops. This reduces the number of nitrogen-fixing soil bacteria. How would this affect the nitrogen cycle?

Recent climate data suggests a global warming trend. Disruption of which natural cycle most likely contributes to this temperature increase?

Fluctuations in the hydrologic cycle could negatively affect a desert biome in all these ways except ―

In a biome, elements such as nitrogen, phosphorous, and carbon move between living things and their environment. These transfers of matter are part of —

Scientists have observed that ecosystems rarely contain more than a few trophic levels. What is the most likely explanation for this observation, based on the second law of thermodynamics?

Food waste in a compost bin gives off heat as it decomposes. What is the best explanation of this phenomenon?

Which of the following is an example of the biosphere using energy from the hydrosphere?

Texas resources can be conserved by doing all of the following except —

If an ecosystem is impacted by an extreme drought over an extended period of time, the import / export rate of which of the following resources would be least impacted?

An average of 2 billion gallons of water is used each day for golf course irrigation in the US. Which of these changes would best aid in reducing the amount of water used for irrigation?

Which of the following is an advantage of recycling garbage over burying waste in landfills or incinerating trash?
