What country currently releases the most carbon dioxide into the atmosphere? the United States Saudi Arabia China Russia Japan India

China

Which of the following statements is most true? Effectively addressing climate change will require a lot of international cooperation, and many countries will need to improve their energy production, their pollution control, and their ecological management practices. Due to their extravagent lifestyles, large and economically developed countries are likely to be the ones most likely to suffer from the effects of climate change. The US is probably responsible for most of the world's climate change. If the world would convert to using electric cars and renewable energy, it is likely that this would solve the climate change problem.

Effectively addressing climate change will require a lot of international cooperation, and many countries will need to improve their energy production, their pollution control, and their ecological management practices.

Which of the following is not a form of geoengineering? Large-scale spraying of sea water into the air to make artifical clouds which reflect incoming sunlight back into space Using aircraft and balloons to release materials into the air to make the atmosphere more reflective, thus lowering the amount of sunlight that hits (and warms) the earth's surface Fertilizing the oceans to encourage algae to grow and use up more carbon dioxide Building large mirrors in space which lower the amount of sunlight striking the earth's atmosphere and surface Encouraging countries and companies around the world to be more energy efficient and to use less fossil fuels

Encouraging countries and companies around the world to be more energy efficient and to use less fossil fuels

According to the notes, the field of environmental science is almost entirely ecology and biology, though sometimes earth science plays a role as well. True False

False

Between 2007 and 2017, the United States significantly increased the fraction of electric power that it generates using coal. True False

False

Experiments carried out at Biosphere 2 showed that it is fairly easy to set up a system that replicates the earth's natural systems. The system was able to successfully recycle waste, grow food, and recycle air. True False

False

Green house gases are generally bad. With the exception of water vapor, the earth would be better off if none of them were in our atmosphere. True False

False

In the United States, if a product is labelled as "natural" the person buying the product can be reasonably sure that the product has been produced in an ecologically sound manner. True False

False

Mining and producing energy from coal causes a lot of pollution. We are also in danger of running out of coal soon. True False

False

Over the past 800,000 years, carbon dioxide levels in the atmosphere have slowly and steadily increased to the current levels of today. True False

False

The cost to generate electricity using photovoltaic (PV) cells (solar panels) has risen significantly since the 1970s. This his resulted in an overall drop in the total amount of energy produced by solar panels during this same time period. True False

False

Unfortunately, the interests of environmentalists and business are almost always directly opposed to each other. Being pro-environment usually means that one is going to be opposed to business interests, and being pro-business means working against environmental preservation and environmental concerns. True False

False

Of the following choices, which state has the the most expensive and which state has the least expensive electricity rates? Maryland, Missouri California, Vermont New York, Wyoming Massachusettes, Alaska Hawaii, North Dakota

Hawaii, North Dakota

Why is ozone important in our atmosphere? It keeps the atmosphere from overheating It protects us from the solar wind and keeps the atmosphere from being graduation stripped away from the planet It keeps the atmosphere from getting too cold Historically, it has kept greenhouse gasses from excessivly accumulating in the atmosphere It protects us from dangerous ultraviolet radiation

It protects us from dangerous ultraviolet radiation

What is "greenwashing"? Using morally questionable or illegal methods to promote environmental causes Planting quick-growing crops to hide environmental damage from regulators and the public Using ecologically sound cleaning products Making a product sound environmentally beneficial and/or environmentally sourced when in fact it may not be Corrupt politicians pretending to support environmental causes will actually promoting environmentally harmful policies

Making a product sound environmentally beneficial and/or environmentally sourced when in fact it may not be

The U.S. National Environmental Education Act of 1990 establishing two goals: to improve public understanding of the interrelationship between humans and the environment, and to encourage postsecondary students to consider having careers related to the environment. True False

True

The United States joined the Paris agreement in 2015, withdrew from the agreement under President Trump, and then rejoined under President Biden. A future president could withdraw the US from the agreement again in the future. True False

True

The federal government, and the fields of environmental law, environmental engineering, and environmental education, can offer career opportunities for persons wishing to work in the environmental field. True False

True

According to the notes, what is the single largest source of energy consumption in the United States? Transportation Military activity Agriculture Industrial production Residential and commerical heating, cooling, and lighting

Transportation

A person in the United States changing from a diet high in red meat to a diet that is mostly vegetarian can save a significant amount of energy, because it usually takes more energy to raise cattle for food than it does to raise plants for food. True False

True

A person in the United States who changes their diet from a diet high in red meat to a diet that is mostly vegetarian can save a significant amount of energy and reduce pollution, because it usually takes more energy and resources to raise cattle for food than it does to raise plants for food. True False

True

Blue Angel and Green Seal are certifications intended to help consumers know that a product is produced in an environmentally sound manner. True False

True

High temperature solar energy power generation concentrates the sun's heat in order to generate high temperatures to drive turbines to generate electricity. Photovoltaic (PV) cells, on the other hand, generate electricity by producing electricity directly from sunlight falling on the solar panel. True False

True

Mining and using coal may cause a lot of pollution but, compared to many other energy sources, it is easy to store and easy to use. True False

What is the difference between climate and weather? Weather deals with temperature, while weather deals with weather (usually rain and snow) Weather is short term (over days or weeks), while climate is long term (over years or decades). Weather is natural, while climate produced by humans Climate deals with temperature, while weather deals with percipitation (usually rain and snow) Climate is short term (over days or weeks), while weather is long term (over years or decades).
