Mr. Elijah is teaching his class about wildlife management strategies. Which of the following is one strategy implemented in wildlife management?
poaching
controlling the pet trade
requirement of hunting permits
crop rotating
Elijah and Lauren are learning about air pollution in science class. They discover that sulfur and nitrogen compounds in the air can combine to form what type of pollution?
ozone
hay fever
smog
ammonia
When Mr. Aiden and Danielle visited a nuclear power plant, they learned that the earliest nuclear fission reactors required the action of an operator to shut down safely in the event of a problem. Today, scientists have designed passively safe nuclear plants that do not require human intervention to shut down safely. Which of the following best describes why the design of fission reactors has changed?
A. The scientists that developed the first nuclear power plants did not care about safety.
B. The scientists that design modern nuclear reactors do not look at earlier designs.
C. Scientists have applied what they learned from early nuclear plants to create better designs.
D. Scientists working on the first nuclear power plants did not know how nuclear fission worked.
Coach, Savannah, and Jordan are discussing the effects of cutting down large areas of trees in the Amazon rain forest. What will most likely be the immediate result of deforestation in this region?
a decrease in the use of alternative energy
an increase in biodiversity in the region
a decrease in the rate of soil erosion
an increase in atmospheric carbon dioxide
Mr. Lauren's class is studying environmental science. They learn that Americans represent about 5% of the world's population, yet they account for the emission of about 50% of the world's automobile exhaust into the atmosphere. Which of the following statements best describes how adding automobile exhaust to the atmosphere has affected the environment?
It has increased the rate of chemical weathering.
It has changed the position of crustal plates.
It has increased the amount of ozone in groundwater.
It has changed Earth's prevailing wind patterns.
During a class discussion, Savannah and Elijah noticed that lead (Pb) levels in the atmosphere have dramatically decreased since the 1980s. What is the main reason for this change?
only unleaded gasoline can be sold at gas stations.
reducing lead emissions from coal-burning power plants.
The use of lead paint to paint cars was outlawed.
Lead pipes have been replaced by copper pipes.
During a science class, Mr. Boddie explains that an odorless, colorless, poisonous gas is produced by the incomplete burning of fossil fuels. He tells Savannah and Sasha that this gas also interferes with the blood's ability to carry oxygen. What is the name of this air pollutant?
asbestos
carbon monoxide
radon
sulfur dioxide
During a science field trip to Yellowstone National Park, Mr. Evan asks Autumn and Xavion, "The geyser Old Faithful is powered by what kind of energy?"
electrical energy
nuclear energy
wind energy
geothermal energy
Mr. Evan explained to Aiden and Skylin that when oil and natural gas are cheap, it leads to what kind of society?
conservative society
consumption-oriented society
nomadic society
agricultural society
Lauren and Aiden are discussing ways to address the increasing demand for food in their community. What is a key goal of the Green Revolution in response to growing food demand?
Promoting the use of traditional farming methods
Increasing food production through the use of high-yield crops, synthetic fertilizers, and advanced technologies
Decreasing the use of pesticides and herbicides
Replacing monocultures with polycultures
Coach is discussing with Evan and Savannah about ways to meet the growing food demand in their community. Which of the following best describes the role of GMOs (Genetically Modified Organisms) in addressing food demand?
GMOs are designed to reduce agricultural production
GMOs can enhance crop yields and increase resistance to pests and diseases
GMOs are primarily used to decrease the size of farms
GMOs are created to replace all organic farming practices
Elijah and Savannah are studying the following graph of global population growth from 1900 to 2020 for their geography project. What effect would this trend have on global food demand?
Global food demand would increase.
Global food demand would decrease.
Global food demand would remain unchanged.
Global food demand would fluctuate unpredictably.
Elijah and Skylin are studying the effects of desertification on global food supply. They learn that desertification influences global food supply by:
reducing the amount of arable land available for agriculture
increasing crop yields worldwide
improving soil fertility in affected regions
expanding the area suitable for farming
During a class discussion, Jordan and Sasha were talking about the start of the industrial revolution. They wondered which fuel source was first exploited to begin this major change in industry. Which of the following did they identify?
coal
nuclear power
petroleum
solar power
Mr. Boddie and his family want to install a new energy system on their farm. They make a list of criteria and constraints for the new energy system.
• Renewable source
• Does not make noise
• No harmful emissions or waste
• Does not need water access
Which source of energy for the system would BEST suit Mr. Boddie's family's needs?
natural gas
solar panels
wind turbines
hydropower
During winter, Lauren and Jordan notice that their community spreads salt on roadways to help melt slippery snow and ice. Salt lowers the melting point of water, which means snow and ice will melt instead of building up on roads. While this helps prevent car accidents, it poses certain problems. What is the most serious problem that could occur to local ecosystems due to road salt?
flooding from too much melting ice and snow
overpopulation because of fewer fatal accidents
damage to plant life because of excess salt in the soil
accidents involving deer and other animals that lick salt
Skylin, Rex, and Jordan are discussing ways to meet energy demands while protecting the environment. Which of the following is the best solution they could choose?
grow more corn to produce ethanol
build more nuclear power plants
find and burn new sources of oil and coal
improve energy efficiency and reduce energy waste
