Question 2

Explain how the greenhouse effect warms Earth and list two greenhouse gases.

Accepted Answer

The answer of Explain how the greenhouse effect warms Earth...

Question 3

Carbon dioxide has rapidly increased in

Accepted Answer

The concentration of carbon dioxide in the atmosphere has increased rapidly in the last 100 years due to human activities such as burning of fossil fuels, deforestation, and industrial processes.

Question 4

The increase in carbon dioxide levels correlates with an increase in

Accepted Answer

Carbon dioxide is a greenhouse gas that traps heat in the Earth's atmosphere, leading to an increase in Earth surface temperature. This phenomenon is known as global warming.

Question 5

The maple tree would most likely be found in which biome?

Accepted Answer

Maple trees are commonly found in temperate deciduous forests, which are characterized by four distinct seasons, moderate precipitation, and a variety of deciduous trees that lose their leaves in the fall. Maple trees are well adapted to this biome's changing seasons and are known for their vibrant fall foliage.

Question 6

Methane is 30 times more powerful than carbon dioxide at absorbing heat.Livestock such as cattle account for 28% of global methane emissions.With this in mind,speculate on the effect of the American diet on global warming.

Accepted Answer

The answer of Methane is 30 times more powerful than...

Question 7

Which statement is FALSE?

Accepted Answer

The ozone hole is not related to greenhouse gas emissions. It is caused by human-made chemicals called chlorofluorocarbons (CFCs) that were once used in products such as refrigerants and aerosol sprays. The use of CFCs has been significantly reduced by international agreements such as the Montreal Protocol, and the ozone hole is slowly recovering.

Question 8

Scientists have used all of the following to document global warming,EXCEPT

Accepted Answer

The thickness of seed coats has not been used to document global warming, while the other options (thermometers, tree rings, historical records, and ice cores) have all been used by scientists to document global warming.

Question 9

What has changed over the last century that makes scientists believe the rise in average global temperature is not just a normal temporary fluctuation?

Accepted Answer

Scientists have observed a significant increase in the amount of carbon dioxide in the atmosphere over the last century, primarily due to human activities such as burning fossil fuels. This increase in carbon dioxide is known to trap more heat in the Earth's atmosphere, leading to a rise in global temperatures. This is supported by numerous scientific studies and measurements. The other options (A, C, D, E) do not provide a sufficient explanation for the observed increase in global temperature.

Question 10

Which of the following is a greenhouse gas?

Accepted Answer

Carbon dioxide, methane, and nitrous oxide are all examples of greenhouse gases. These gases trap heat in the Earth's atmosphere, leading to the phenomenon known as global warming. Oxygen, on the other hand, is not a greenhouse gas and does not contribute to global warming.

Question 11

The greenhouse gases include

Accepted Answer

The greenhouse gases are primarily composed of carbon dioxide, methane, and nitrous oxide. Carbon monoxide and nitrogen are not considered greenhouse gases, and while ozone does contribute to the greenhouse effect, it is a much less significant greenhouse gas compared to the other three listed in option D. Sulphur is also not considered a greenhouse gas.

Question 12

.High elevations are cooler than lower elevations.Knowing this,what are the consequences of global warming for the following species living at the top of a mountain: (1)a mouse,(2)a bird,(3)a plant that relies on mammals to distribute its seeds,and (4)a plant that relies on wind to distribute its seeds? Briefly explain your answers.

Accepted Answer

The answer of .High elevations are cooler than lower elevations.Knowing...

Question 13

Which is NOT a naturally occurring greenhouse gas?

Accepted Answer

Chlorofluorocarbons (CFCs) are not naturally occurring greenhouse gases. They are man-made chemicals released by activities such as refrigeration, air conditioning, and aerosol sprays.

Question 14

The vegetation in a biome is largely influenced by

Accepted Answer

The vegetation in a biome is largely influenced by both temperature and precipitation. Both of these factors affect the types of plants that can grow and thrive in a particular area. For example, arid regions with limited precipitation may only support plants that are adapted to dry conditions, while colder regions with less sunlight may support plants with specialized adaptations to low temperatures. Therefore, a combination of temperature and precipitation determines the types of vegetation that can survive and grow in a particular biome.

Question 15

All of the following are true of the greenhouse effect,EXCEPT

Accepted Answer

High oxygen levels are not contributing to global warming. It is actually the increased levels of greenhouse gases, such as carbon dioxide, methane, and water vapor, that are trapping more heat in the atmosphere and causing the greenhouse effect to increase.

Question 16

In the face of rising temperatures,which organism below has the greatest disadvantage?

Accepted Answer

As temperatures rise, the range of sugar maple trees is likely to shift northward. However, as these trees rely on specific soil and moisture conditions, they may struggle to adapt to new regions. Additionally, rising temperatures may lead to increased stress and disease susceptibility for sugar maples. In contrast, the other organisms listed either have greater adaptability or may even benefit from higher temperatures.

Question 17

Increases in greenhouse gases

Accepted Answer

Greenhouse gases, such as carbon dioxide and methane, trap heat in Earth's atmosphere, leading to an increase in global temperatures and climate change.

Question 18

Match up terrestrial biome to plant inhabitant.
A. Rainforest ____ Pine tree
B. Temperate deciduous forest ____ Cactus
C. Grassland ____ Maple tree
D. Coniferous forest ____ Sunflower
E. Desert ____ Bryophytes
F. Tundra ____ Palm tree

Accepted Answer

The answer of Match up terrestrial biome to plant inhabitant.
A....

Question 19

Which is NOT true of greenhouse gases?

Accepted Answer

Greenhouse gases have been present in Earth's atmosphere for millions of years. However, human activities have significantly increased the amount of greenhouse gases, leading to an enhanced greenhouse effect and climate change.

Question 20

What evidence supports an increase in Earth's surface temperature?

Accepted Answer

All of the above options provide evidence of an increase in Earth's surface temperature. Historical records document temperature changes over time, while tree rings and ice cores provide information about temperature fluctuations in the past. Corals can also be used to study changes in ocean temperature. Combining these different sources of evidence offers a more comprehensive understanding of how and why Earth's temperature is changing.
