What animals were on the verge of disappearing in China?
- A.
Seahorses
- B.
Dogs
- C.
Bears
- D.
Dragon
Correct Answer
A. SeahorsesExplanation
Seahorses were on the verge of disappearing in China. This suggests that the seahorse population in China was declining rapidly and facing the risk of extinction. The other options, such as dogs, bears, and dragons, do not provide any information about their population status in China. Therefore, the correct answer is seahorses.Rate this question:

Ozone reduction is caused by…
- A.
Global warming
- B.
Greenhouse gases
- C.
Both are correct
- D.
None are correct
Correct Answer
C. Both are correctExplanation
Both global warming and greenhouse gases contribute to ozone reduction. Global warming leads to an increase in temperature, which in turn accelerates the chemical reactions that deplete ozone in the stratosphere. Greenhouse gases, such as chlorofluorocarbons (CFCs), release chlorine and bromine atoms when they break down in the atmosphere. These atoms then catalytically destroy ozone molecules. Therefore, both factors play a role in the reduction of ozone.Rate this question:

Does hot water cause pollution?
- A.
Yes
- B.
No
- C.
Sometimes
- D.
Occassionaly
Correct Answer
A. YesExplanation
Hot water can cause pollution because it requires energy to heat it, and the majority of energy sources produce pollution. For example, if hot water is heated using fossil fuels like coal or natural gas, it releases carbon dioxide and other greenhouse gases into the atmosphere, contributing to climate change. Additionally, the process of heating water can also lead to the release of pollutants such as sulfur dioxide and nitrogen oxides if the energy source is not properly controlled or filtered. Therefore, hot water can be a source of pollution depending on how it is heated.Rate this question:

Water pollution caused by sewage is damaging because...
- A.
Introduce dangerous pathogens
- B.
Aerobic bacteria use large quantities of oxygen to decompose sewage
- C.
All are true
- D.
None are true
Correct Answer
C. All are trueExplanation
Water pollution caused by sewage is damaging because it introduces dangerous pathogens and aerobic bacteria use large quantities of oxygen to decompose sewage. Pathogens present in sewage can pose a significant risk to human health, leading to waterborne diseases. Additionally, the decomposition of sewage by aerobic bacteria consumes a large amount of dissolved oxygen in the water, which can harm aquatic life and disrupt the ecosystem. Therefore, both statements are true and contribute to the damaging effects of water pollution caused by sewage.Rate this question:

In your opinion deforestation have consequences to the environment?
- A.
Maybe
- B.
Serious consequences such us soil erosion
- C.
Of course not
- D.
Yes
Correct Answer
B. Serious consequences such us soil erosionExplanation
Deforestation can indeed have serious consequences for the environment, such as soil erosion. When trees are cut down, the roots that hold the soil in place are removed, leading to increased erosion. This can result in the loss of fertile soil, decreased water quality, and damage to ecosystems. Additionally, deforestation contributes to climate change as trees absorb carbon dioxide, a greenhouse gas. Therefore, the given answer correctly acknowledges the serious consequences, specifically soil erosion, that deforestation can have on the environment.Rate this question:

Pesticides can be avoid in agriculture...
- A.
Increasing the use of fertilizers
- B.
Using new varieties of crop
- C.
Draining water
- D.
None of the above
Correct Answer
B. Using new varieties of cropExplanation
Using new varieties of crop can help in avoiding the use of pesticides in agriculture. New varieties of crops are often bred to be resistant to pests and diseases, reducing the need for chemical pesticides. These crops are genetically modified or selectively bred to have traits that make them naturally resistant to common pests, thereby reducing the reliance on harmful pesticides. By using new varieties of crop, farmers can minimize the negative impact of pesticides on the environment and human health while still maintaining high crop yields.Rate this question:

How different would Earth be if the greenhouse effect didn't exist?
- A.
The same temperature
- B.
A little cooler than it is now
- C.
Too cold to live
- D.
A little warmer than it is now
Correct Answer
C. Too cold to liveExplanation
If the greenhouse effect didn't exist, Earth would be too cold to sustain life. The greenhouse effect is the process by which certain gases in the Earth's atmosphere trap heat from the sun, keeping the planet warm. Without this effect, the Earth's average temperature would drop significantly, making it too cold for most living organisms to survive. This would have drastic consequences for ecosystems, agriculture, and the overall balance of the planet.Rate this question:

Why is firewood regarded as a resource that can be replenished?
- A.
It can be replenished over time
- B.
It is used up faster than it can form
- C.
It is made from coal
- D.
It is made from coal
Correct Answer
A. It can be replenished over timeExplanation
Firewood is regarded as a resource that can be replenished because it can be replaced or restored over time. Trees, which are the primary source of firewood, can be grown and harvested sustainably. As long as there is proper management and responsible harvesting practices in place, new trees can be planted to replace the ones that are cut down for firewood. This ensures that there is a continuous supply of firewood without depleting the resource completely.Rate this question:

Which of the following is not a resource that can be replenished?
- A.
Solar energy
- B.
Coal
- C.
Water
- D.
Wind energy
Correct Answer
B. CoalExplanation
Coal is not a resource that can be replenished. Unlike solar energy, water, and wind energy, coal is a non-renewable resource that takes millions of years to form. Once coal is extracted and burned for energy, it cannot be replaced or regenerated within a human lifetime. Therefore, coal is not a sustainable resource and its use contributes to environmental degradation and climate change.Rate this question:

What is the final stage of succession called?
- A.
Secondary community
- B.
Climax community
- C.
End phase
- D.
Terminal Community
Correct Answer
B. Climax communityExplanation
The final stage of succession is called the climax community. This is the stable and mature community that develops after a series of ecological changes and transitions. It represents the most diverse and complex stage of succession, where the community has reached a state of equilibrium with its environment. The climax community is characterized by a balance between the species present and the environmental conditions, and it can persist for a long period of time if not disturbed by major disturbances.Rate this question:
