Under _____ conditions, a portion of the outgoing infrared radiation is naturally _____ by the atmosphere.
Correct Answer
A. Normal / trapped
Explanation
Under normal conditions, a portion of the outgoing infrared radiation is naturally trapped by the atmosphere. This is because certain gases in the atmosphere, such as carbon dioxide and water vapor, have the ability to absorb and re-emit infrared radiation. This trapping of infrared radiation is known as the greenhouse effect and is essential for maintaining Earth's temperature and supporting life.
6.
The causes of Global Warming can be split up into the following groups:
Correct Answer
C. Natural causes and Human causes
Explanation
The correct answer is "Natural causes and Human causes." Global warming is primarily caused by a combination of natural factors, such as volcanic eruptions and variations in solar radiation, and human activities, including the burning of fossil fuels and deforestation. These natural causes contribute to the greenhouse effect, trapping heat in the Earth's atmosphere, while human causes intensify the effect by increasing the concentration of greenhouse gases. Therefore, both natural and human causes play a significant role in global warming.
7.
The main natural causes are:
Correct Answer(s)
A. Solar cycles and sunspots
C. Climate changes cycles
D. The rotation of the Earth
Explanation
Solar cycles and sunspots, climate change cycles, and the rotation of the Earth are all natural causes that can affect various aspects of the environment. Solar cycles and sunspots refer to the periodic variations in the Sun's activity, which can influence climate patterns on Earth. Climate change cycles refer to the natural fluctuations in climate over long periods of time, such as ice ages and interglacial periods. The rotation of the Earth affects the distribution of sunlight and the formation of weather patterns. These natural causes play significant roles in shaping the Earth's climate and environment.
8.
The man-made causes of Global Warming are:
Correct Answer(s)
A. Carbon dioxide emissions from fossil fuel burning power plants
B. Carbon dioxide emissions from burning gasoline for transportation
C. Deforestation, especially tropical forests for wood, pulp, and farmland
Explanation
The man-made causes of Global Warming include carbon dioxide emissions from fossil fuel burning power plants, carbon dioxide emissions from burning gasoline for transportation, and deforestation, especially of tropical forests for wood, pulp, and farmland. These activities release significant amounts of greenhouse gases into the atmosphere, particularly carbon dioxide, which traps heat and contributes to the warming of the Earth's climate. Additionally, climate change cycles can also contribute to global warming, although it is not clear what is meant by this term in the given context.
9.
With our population decreasing at an alarming rate, the demand for more cars and consumer goods means that we are reducing the use of fossil fuels for transportation and manufacturing
Correct Answer
B. False
Explanation
The given statement suggests that the population is decreasing, which would imply a decrease in the demand for cars and consumer goods. If the demand for these goods is decreasing, it would mean that the use of fossil fuels for transportation and manufacturing is also decreasing. However, the statement contradicts this by stating that the demand for more cars and consumer goods is increasing. Therefore, the answer is False.
10.
The main effects of Global Warming are:
Correct Answer(s)
A. Rise in sea levels worldwide
B. More killer storms
C. Displacement of millions of people
Explanation
The correct answer is rise in sea levels worldwide, more killer storms, and displacement of millions of people. Global warming refers to the increase in Earth's average surface temperature due to the buildup of greenhouse gases in the atmosphere. As a result, the polar ice caps and glaciers melt, causing sea levels to rise. The warming of the planet also leads to changes in weather patterns, resulting in more intense and frequent storms. Additionally, the impacts of global warming, such as extreme weather events and rising sea levels, can force people to leave their homes, leading to the displacement of millions of individuals.
11.
Which facts evidence that Global Warming is occurring just now?
Correct Answer
B. More heat returning to Earth
Explanation
The fact that more heat is returning to Earth provides evidence that global warming is occurring. This is because greenhouse gases, such as carbon dioxide, trap heat in the atmosphere, causing the Earth's temperature to rise. As the concentration of these gases increases due to human activities, more heat is trapped and returned to the Earth's surface, leading to global warming.
12.
Which elements take part in the basic science of Global Warming?
Correct Answer(s)
A. The greenhouse gases
C. The infrared radiation
D. The Sun
Explanation
The elements that take part in the basic science of Global Warming are the greenhouse gases, the infrared radiation, and the Sun. Greenhouse gases, such as carbon dioxide and methane, trap heat in the Earth's atmosphere, leading to an increase in global temperatures. Infrared radiation is the form of energy that is emitted by the Earth and absorbed by greenhouse gases, contributing to the warming effect. The Sun provides the initial energy that drives the Earth's climate system, including the heating of the atmosphere and the oceans.
13.
The global temperatures of the Earth show a _____ trend to the increase of carbon dioxide in the atmosphere.
