Question 1

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

Accepted Answer

High oxygen levels are not contributing to global warming. The main greenhouse gases responsible for trapping heat in the Earth's atmosphere are carbon dioxide, methane, and water vapor.

Question 2

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 3

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

Accepted Answer

All of the above provide evidence for an increase in Earth's surface temperature. Historical records indicate a rise in global temperature since the industrial era, tree rings provide information on past climate conditions, ice cores in Greenland and Antarctica reveal changes in atmospheric composition and temperature over the past 800,000 years, and corals contain growth bands that record past ocean temperatures. Together, these sources provide a compelling picture of global warming.

Question 4

The vegetation in a biome is largely influenced by

Accepted Answer

Both temperature and precipitation play a crucial role in determining the type of vegetation that can grow in a particular biome. Temperature affects the rate of photosynthesis and respiration in plants, while precipitation provides the necessary water and nutrients for their growth. Therefore, the combination of temperature and precipitation defines the biome and the vegetation that can thrive in it. Geographical location and migration patterns can also affect the vegetation, but they are not the primary factors that determine the biome.

Question 5

Which is NOT a naturally occurring greenhouse gas?

Accepted Answer

Chlorofluorocarbons (CFCs) are not naturally occurring greenhouse gases. They were originally developed as refrigerants, solvents, and propellants but have since been banned in many countries due to their detrimental effects on the ozone layer.

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

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

Accepted Answer

The maple tree is commonly found in the temperate deciduous forest biome, which is characterized by trees that lose their leaves seasonally.

Question 8

Which of the following is a greenhouse gas?

Accepted Answer

Carbon dioxide, methane, and nitrous oxide are all greenhouse gases because they trap heat in the Earth's atmosphere and contribute to global warming. Oxygen is not a greenhouse gas as it does not have the ability to trap heat in the atmosphere.

Question 9

The increase in carbon dioxide levels correlates with an increase in

Accepted Answer

Carbon dioxide is a greenhouse gas, and its increase in the atmosphere traps more of the sun's energy, causing an increase in the Earth's surface temperature. This is known as the greenhouse effect.

Question 10

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

The increase in carbon dioxide in the atmosphere, primarily due to human activity such as burning fossil fuels, has been identified as the main contributor to the rise in average global temperature. This change is not just a normal temporary fluctuation, but a significant and ongoing trend.

Question 11

Which statement is FALSE?

Accepted Answer

The ozone hole is not getting bigger because of greenhouse gas emissions, but rather because of the release of chemicals like chlorofluorocarbons (CFCs).

Question 12

The greenhouse gases include

Accepted Answer

The three greenhouse gases are carbon dioxide, methane, and nitrous oxide. Option A is incorrect because nitrogen is not a greenhouse gas, and ozone is a greenhouse gas but not one of the top three. Option B is incorrect because carbon monoxide is not a greenhouse gas. Option C is incorrect because nitrogen is not a greenhouse gas and carbon monoxide is not one of the top three. Option E is incorrect because sulphur is not a greenhouse gas.

Question 13

Increases in greenhouse gases

Accepted Answer

Greenhouse gases, such as carbon dioxide, trap heat in Earth's atmosphere and contribute to the warming of the planet. This is known as the greenhouse effect.

Question 14

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 15

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 16

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

Accepted Answer

Seed-coat thickness has not been used as a documented source for global warming. All the other options have been used by scientists to document global warming. Thermometers measure changes in temperature, tree rings can indicate changes in climate, historical records document past temperatures, and ice cores preserve information about the atmosphere from the past.

Question 17

Which is NOT true of greenhouse gases?

Accepted Answer

The statement "Greenhouse gases are relatively new in Earth's atmosphere" is not true. Greenhouse gases have always been present in Earth's atmosphere, but the levels of greenhouse gases have increased significantly since the Industrial Revolution due to human activities such as burning fossil fuels.

Question 18

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

Accepted Answer

Sugar maple trees have specific temperature and moisture requirements, and changes in temperature or precipitation can negatively impact their growth and survival. Rising temperatures can also alter the timing of important life cycle events, such as leaf emergence and flowering, which can further impact their ability to survive and reproduce.

Question 19

Carbon dioxide has rapidly increased in

Accepted Answer

Carbon dioxide levels have been measured for centuries and have shown a steep increase in the last 100 years due to human activities such as burning fossil fuels and deforestation.

Question 20

How would you respond to someone who says that the increase in global temperatures of the last 200 years is just part of normal global temperature fluctuations?

Accepted Answer

The answer of How would you respond to someone who...
