How did Earth's atmosphere change throughout the first two billion years of its existence?
In the first two billion years of Earth's existence, the atmosphere underwent significant changes. Initially, it was composed mainly of gases like carbon dioxide and methane, which created a greenhouse effect and maintained high temperatures. Over time, as photosynthetic organisms evolved and produced oxygen, the atmosphere gradually transformed into the oxygen-rich composition we have today.
How does ozone enhance the greenhouse effect?
Ozone depletion causes plankton to die. These plankton are the ones that stop greenhouse effect.
What has an effect on air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
What has the author Wendy Danielle Ransom written?
Wendy Danielle Ransom has written: 'Effect of cyclic AMP on membrane polarity and photosynthetic carbon assimilation in natural planktonic communities' -- subject(s): Botany, Photosynthesis, Freshwater plankton
What has an effect on earths air pressure?
gas composition of atmosphere (including water vapour); altitude; temperature; and wind velocity.
What effect did photosynthetic cyanobacteria have on earth's environment?
Photosynthetic cyanobacteria were the first organisms to produce oxygen. The effect of their oxygen production was that the earth became an environment which was suitable for life.
How might the photosynthetic organisms counter the greenhouse effect?
Photosynthetic organisms counter the greenhouse effect. This is because plants use carbon dioxide and turns it into oxygen instead. Carbon dioxide is causing the greenhouse effect.
Is the plankton effect on the environment positive or negative?
positive
Is it true that the planet's atmosphere and temperature are related?
Oh yes, the chemical composition of the atmosphere has an effect on the temperature. This is known as the greenhouse effect. Carbon dioxide, in particular, has the capacity to retain heat. So as the amount of carbon dioxide in the atmosphere increases, the world gets warmer. The world is wrapped in an invisible blanket.
What is the effect of a tsunami on plankton?
nothing except they expand their ecosystem
Which planet's cloudiness results in the greenhouse effect?
Mercury has no atmosphere, so that can't be it. Venus has a dense atmosphere, and is entirely enshrouded in clouds. It isn't the clouds on Venus that result in the greenhouse effect so much as the composition of its atmosphere. The air on Venus is mostly carbon dioxide, a heat trapping gas, and this has resulted in a runaway effect making Venus the hottest planet in our solar system.
How does the composition of the atmosphere effect the existence of life?
The composition of the atmosphere is crucial for the existence of life as it provides essential gases like oxygen for respiration and carbon dioxide for photosynthesis. A balanced atmospheric mix maintains temperature stability through the greenhouse effect, protecting organisms from extreme temperature fluctuations. Additionally, the atmosphere helps shield the Earth from harmful solar radiation, creating a suitable environment for diverse life forms to thrive. Changes in atmospheric composition, such as increased pollutants or greenhouse gases, can disrupt these vital processes and threaten ecosystems.
