Which is true about the greenhouse effect?

The greenhouse effect is a natural process that warms the Earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. The absorbed energy warms the atmosphere and the surface of the Earth. …

Which statement describes the greenhouse effect?

Carbon dioxide has increased as a result of increased human activities. Which statement best describes the greenhouse effect? It is a process by which plants are able to grow well in a warm, enclosed structure. It is a process by which greenhouse gases block the sun’s light to penetrate the atmosphere.

Which of the following best describes how the greenhouse effect works?

Which of the following best describes how the greenhouse effect works? A planet’s surface absorbs visible sunlight and returns this absorbed energy to space as infrared light. Greenhouse gases slow the escape of this infrared radiation, which thereby heats the lower atmosphere.

Which of the following is a strong greenhouse gas?

Water vapor is the most potent of the greenhouse gases in Earth’s atmosphere, and it’s sort of a unique player among the greenhouse gases. The amount of water vapor in the atmosphere cannot, in general, be directly modified by human behavior—it’s set by air temperatures.

What is the significance of greenhouse gas?

Greenhouse gases keep our planet livable by holding onto some of Earth’s heat energy so that it doesn’t all escape into space. This heat trapping is known as the greenhouse effect. Just as too little greenhouse gas makes Earth too cold, too much greenhouse gas makes Earth too warm.

Where do the majority of greenhouse gases come from?

In the United States, most of the emissions of human-caused (anthropogenic) greenhouse gases (GHG) come primarily from burning fossil fuels—coal, hydrocarbon gas liquids, natural gas, and petroleum—for energy use.

Is Sulphur dioxide a greenhouse gas?

Sulfur dioxide, like nitrogen dioxide, is one of the six designated air pollutants. While sulfur dioxide isn’t a direct greenhouse gas like carbon dioxide or methane, it is considered an indirect greenhouse gas.

Which of the following does not lead to greenhouse effect?

1. Carbon dioxide produced whenever coal, oil, natural gas, and other fossil carbon-rich fuels are burned. Carbon monoxide is not a primary greenhouse gas.

What is the GHG Protocol?

What is GHG Protocol? GHG Protocol establishes comprehensive global standardized frameworks to measure and manage greenhouse gas (GHG) emissions from private and public sector operations, value chains and mitigation actions.

Why is methane a powerful greenhouse gas?

Methane as a Greenhouse Gas Methane, along with carbon dioxide and other molecules, contributes significantly to the greenhouse effect. Due to the chemical bonds within its molecule methane is much more efficient at absorbing heat than carbon dioxide (as much as 86 times more), making it a very potent greenhouse gas.

Are greenhouse gases harmful?

Greenhouse gases have far-ranging environmental and health effects. They cause climate change by trapping heat, and they also contribute to respiratory disease from smog and air pollution. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.

Are greenhouse gases good for the environment?

Greenhouse gases are gases that can trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. Overall, greenhouse gases are a good thing. Without them, our planet would be too cold, and life as we know it would not exist.

Why is the greenhouse effect considered a bad thing?

Too many greenhouses gases, and the sun’s heat gets trapped in the atmosphere, warming the planet and the oceans. Global warming leads to severe weather extremes: droughts and floods, hot, hot summers and freezing winters.
