What do we mean by a runaway greenhouse effect What do we mean by a runaway greenhouse effect?

A runaway greenhouse effect occurs when a net positive feedback between surface temperature and atmospheric opacity increases the greenhouse effect on a planet until it’s oceans boil away.

What causes a runaway greenhouse effect quizlet?

The runaway greenhouse effect is caused by when a planet receives too much heat from the Sun and its emitted back out into space. Venus’ cloud clover blocks the emission of this heat back into space, thus trapping it in the atmosphere and heating the surface.

What is an example of a runaway greenhouse effect?

A few billion years ago, high levels of carbon dioxide in the Venusian atmosphere may have trapped enough heat to trigger a global SGE that boiled away the oceans. This is known as a runaway greenhouse effect. Today, the surface of Venus is hot enough to melt lead.

What will most likely cause the Earth to have a runaway greenhouse effect?

A runaway greenhouse effect occurs when a planet’s atmosphere contains greenhouse gas in an amount sufficient to block thermal radiation from leaving the planet, preventing the planet from cooling and from having liquid water on its surface.

What causes the greenhouse effect quizlet astronomy?

What causes the greenhouse effect? Water vapor and carbon dioxide absorb visible sunlight and warms the atmosphere. Ozone absorbs solar ultraviolet radiation and warms the atmosphere. Oxygen and nitrogen scatter sunlight which heats the atmosphere by its frictional passage.

Where does the greenhouse effect occur quizlet?

Terms in this set (12) What is Greenhouse Effect? Earth that occurs when carbon dioxide, water vapor, and other gases in the air absorb and radiate infrared radiation.

What initiated the runaway greenhouse effect on Venus quizlet?

Venus is too close to the sun to have permanent oceans, so there was not a way to remove carbon dioxide from its atmosphere. The large amount of carbon dioxide in the atmosphere caused a runaway greenhouse effect.

What does the greenhouse effect do to a planet quizlet?

Therefore, greenhouse gases trap the energy in the form of infrared light that the surface of the planet is emitting, not allowing the excess energy/heat to be released. Because of the greenhouse effect, we end with a higher temperature on the surface of the than we would without that trapped energy.

What is the cause of greenhouse effect rays?

-The greenhouse gases present in the atmosphere absorb more of the infrared radiations as compared to UV, X and radio waves, which are unable to escape the atmosphere and cause the temperature of the earth to rise, resulting in a greenhouse effect.
