Why do scientist think the the amount of oxygen in the earth's atmosphere has increased?
Scientists believe that the amount of oxygen in Earth's atmosphere has increased over time due to the evolution of photosynthetic organisms, such as plants and cyanobacteria. These organisms release oxygen as a byproduct of photosynthesis, leading to an accumulation of oxygen in the atmosphere.

How did earths atmosphere change during precambrian time?
During the Precambrian time, the Earth's atmosphere underwent significant changes, transitioning from a reducing atmosphere dominated by gases like methane and ammonia to an oxidizing atmosphere with increasing levels of oxygen, due to the development of photosynthetic organisms. This increase in oxygen levels laid the foundation for the evolution of complex multicellular life forms.
Why did the amount of oxygen's in earths atmosphere increase dramatically?
The amount of oxygen in the atmosphere increased because the number of photosynthetic organisms, which release oxygen, on the earth dramatically increased. This lead to the Great Oxygenation Event, or the Oxygen Crisis, 2.4 billion years ago - when this free O2 entered the Earth's atmosphere.
How does burning coal affect the amount of carbon dioxide in the earths atmosphere?
Burning coal releases carbon dioxide (CO2) into the atmosphere. Since CO2 is a greenhouse gas, it traps heat and contributes to global warming and climate change. The increased levels of CO2 from burning coal contribute to the enhanced greenhouse effect, leading to rising temperatures and other environmental impacts.
What is earths energy balance?
Earth's energy balance refers to the equilibrium between the amount of solar energy that reaches Earth and the amount that is reflected back into space. This balance is maintained by processes such as absorption, reflection, and emission of energy by Earth's atmosphere, land, and oceans. Any disruptions to this balance, such as increased greenhouse gas concentrations, can lead to global warming and climate change.
What is the name of the model that scientist use to describe air circulation in earths atmosphere?
The model that scientists use to describe air circulation in Earth's atmosphere is called the Global Circulation Model (GCM). These models simulate the interactions between the atmosphere, oceans, land surface, and ice to predict climate patterns and changes.
What type of scientist study objects beyond the earths atmosphere?
Biologist
What does gas do to some scientist think was missing from earths early atmosphere?
oxygen
What gas do scientist think was missing from earths early atmosphere?
Methane gas
What gas do some scientist think was missing from earths atmosphere?
Methane gas
What are the advantages of using a spectroscope?
it has increased vision since its out of earths atmosphere

What is the amount of heat energy in the earths atmosphere referred to as?
the altitude
What causes global warming in the world today?
The increased use of fossil fuel has increased the amount of greenhouse gases in the atmosphere. This has caused the suns light to be trapped inside the earths atmosphere and leads to the rise in the temperature. This will lead to the melting of the polar ice sheets which reduce the suns light to be reflected back.
What greenhouse gas produced by humans activities has dramatically increased in earths atmosphere?
CO2; Carbon Dioxide
What would happen to animals if the amount of oxygen the earths atmosphere decreased?
youll die
Why did the amount of oxygen's in earths atmosphere increase dramatically?

Where did the gases in the earths atmosphere come from?
Scientist theorize that bacteria with chlorophyll in them slowly but surely began to multiply. And as they did, they photosynthesized enough to create an entire atmosphere. (as you know oxygen is a byproduct of photosynthesis)
