Which Of The Following Sums Up The Greenhouse Effect Quizlet The Best?

The greenhouse effect is a natural process that occurs when certain gases, such as carbon dioxide and water vapor, accumulate in Earth’s atmosphere. These gases allow the sun’s light to penetrate the atmosphere but stop it, leading to the heating of the lower atmosphere. The greenhouse effect is a natural process responsible for keeping the Earth at the temperature needed to sustain life by naturally trapping heat in the atmosphere.

The greenhouse effect is a result of human activities, particularly our combustion of fossil fuels, which are changing the global climate. The scientific consensus is clear: through alterations of the carbon cycle, humans are changing the global temperature. The greenhouse effect acts like the glass walls of a greenhouse, absorbing heat from the sun and transferring it to the atmosphere.

The greenhouse effect is necessary for life on Earth because it heats the Earth’s surface. A planet’s surface absorbs visible sunlight and returns this absorbed energy to space. The greenhouse effect is a result of human activities, particularly our combustion of fossil fuels, which contribute to the current warming. The greenhouse effect is a crucial part of the Earth’s climate, as it helps to maintain the Earth’s temperature and sustain life.

Which describes the greenhouse effect?

The greenhouse effect occurs when infrared radiation from the Sun is absorbed and re-emitted by greenhouse gas molecules and clouds, causing the Earth’s surface and lower atmosphere to warm. These gases absorb heat from the Sun, which is circulated in the atmosphere and eventually lost to space. They also increase the rate at which the atmosphere can absorb short-wave radiation from the Sun, but this has a weaker effect on global temperatures. The release of CO2 from burning fossil fuels accumulates as an insulating blanket around Earth, trapping more of the Sun’s heat in our atmosphere.

Which explanation correctly describes the greenhouse effect?

The greenhouse effect is the natural warming of the Earth caused by gases trapping heat from the sun, which would otherwise escape into space. This process, identified by scientists in the 1800s, makes the Earth habitable. Around 30% of solar energy reaches the Earth, while the rest is absorbed by the atmosphere or Earth’s surface. This process warms the planet, causing infrared radiation to be absorbed by atmospheric gases, causing further warming.

However, higher concentrations of greenhouse gases, particularly carbon dioxide (CO2), are causing extra heat to be trapped and causing average global temperatures to rise. For most of the past 800, 000 years, CO2 concentration in the atmosphere was between 200 and 280 parts per million. However, in 2013, due to burning fossil fuels and deforestation, CO2 in the Earth’s atmosphere surpassed 400 parts per million, a level not seen on the planet for millions of years. As of 2023, it has reached over 420 parts per million, 50% higher than preindustrial levels.

What is the correct statement about greenhouse effect?

Greenhouse gases in the Earth’s atmosphere absorb thermal radiation from the Earth’s surface, causing the “greenhouse effect” and increasing the planet’s temperature. The UGC NET Provisional Answer Key for the UGC – NET June 2024 (Rescheduled) Examination has been released, with candidates able to challenge the answer key from September 11th to September 13th. The exam, covering over 80 subjects, determines eligibility for Junior Research Fellowship and Assistant Professor posts.

What is the statement of the greenhouse effect?

Greenhouse gases play a crucial role in maintaining Earth’s temperature for life. Without the natural greenhouse effect, Earth’s heat would escape into space, resulting in an average temperature of around -20°C. The greenhouse effect occurs when most infrared radiation from the Sun passes through the atmosphere, but most is absorbed and re-emitted by greenhouse gas molecules and clouds. This warms the Earth’s surface and lower atmosphere.

Greenhouse gases absorb infrared radiation in the form of heat, which is circulated in the atmosphere and eventually lost to space. They also increase the rate at which the atmosphere can absorb short-wave radiation from the Sun, but this has a weaker effect on global temperatures.

What is the best explanation for the greenhouse effect?

The greenhouse effect is a phenomenon where Earth’s atmosphere traps the Sun’s heat, causing it to become warmer than it would be without an atmosphere. This process is a key factor in making Earth a comfortable place to live. Greenhouses, which are buildings with glass walls and roofs, are used to grow plants like tomatoes and tropical flowers. The greenhouse effect is a result of the Earth’s greenhouse gases trapping the Sun’s heat, making it a more conducive environment for life.

What describes the greenhouse effect?

The greenhouse effect is a process where heat is trapped near Earth’s surface by greenhouse gases, such as carbon dioxide, methane, ozone, nitrous oxide, chlorofluorocarbons, and water vapor. These gases help maintain a warmer temperature than it would otherwise have. Carbon dioxide is crucial for maintaining Earth’s atmosphere stability, as it would collapse the terrestrial greenhouse effect and drop Earth’s surface temperature by approximately 33°C (59°F).

Earth is often called the ‘Goldilocks’ planet due to its natural greenhouse effect, which maintains an average temperature of 15°C (59°F). However, human activities, primarily from burning fossil fuels, have disrupted Earth’s energy balance, leading to an increase in carbon dioxide in the atmosphere and ocean. The level of carbon dioxide in Earth’s atmosphere has been rising consistently for decades, trapping extra heat near the planet’s surface and causing temperatures to rise.

What is the explanation for greenhouse effect?

The greenhouse effect can be defined as the trapping of heat near Earth’s surface by greenhouse gases, which act as a warm blanket, thereby causing the planet to remain warmer than it would otherwise.

What statement best describes the greenhouse effect?

The greenhouse effect is defined as a phenomenon whereby greenhouse gases permit the entry of solar radiation into the atmosphere while simultaneously preventing the escape of thermal energy.

What is the best explanation for the greenhouse effect quizlet?

The greenhouse effect is a phenomenon whereby the Earth’s temperature is elevated as a consequence of the accumulation of excess greenhouse gases, which impede the release of energy that would otherwise be emitted.

Which of the following best summarizes the greenhouse effect?

The greenhouse effect is a phenomenon whereby the Earth’s surface absorbs solar energy, emits long-wave radiation, which is subsequently absorbed by water vapor, carbon dioxide, and other atmospheric trace gases, which then emit some of the energy back to Earth.
