How did oxygen become a part of earth's atmosphere and what did this increase in oxygen levels allow?
The majority of oxygen in the atmosphere come from photosynthesis. Aquatic Cyanobacteria (blue green algae) were the first known organisms to use photosynthesis, before there were land plants. The by product of photosynthesis is oxygen. This increase in oxygen eventually allowed organisms to use respiration as a method of energy production. Thus it allowed for land animals.
What else can I help you with?
Earths early atmosphere was changed dramatically by the evolution of?
photosynthetic organisms, like cyanobacteria, which produced oxygen as a byproduct of photosynthesis. This led to the increase in atmospheric oxygen levels, changing the composition of Earth's early atmosphere.
What happens when levels of greenhouse gases in Earths atmosphere increase?
When levels of greenhouse gases increase in Earth's atmosphere, they trap more heat from the sun, leading to global warming and climate change. This can cause rising temperatures, melting ice caps, more frequent and severe weather events, and disruptions to ecosystems and habitats. It is essential to reduce greenhouse gas emissions to mitigate these impacts.
How has the amount of oxygen in earths atmosphere changed over time?
The amount of oxygen in Earth's atmosphere has fluctuated over geological time scales. Oxygen levels were much lower in the past, particularly in the early stages of Earth's history. Around 2.4 billion years ago, there was a significant increase in oxygen levels known as the Great Oxidation Event, leading to the current levels of approximately 21% oxygen in the atmosphere.
How did oxygen become a part of the earths atmosphere and what did this increase in oxygen levels allow?
The oxygen in the atmosphere is the O-Zone which is O3 (Oxygen 3) because of plant life oxygen had increased via photosynthesis, the incease just allowed the ozone to thicken, but sadly due to CFC there are large holes
What is the effects of heating the earths atmosphere?
Heating the Earth's atmosphere leads to global warming, causing changes in climate patterns, rising sea levels, and more extreme weather events. This increase in temperature is primarily driven by human activities, such as the burning of fossil fuels and deforestation, which release greenhouse gases into the atmosphere.

What will not increase the levels of carbon dioxide in the atmosphere?
Not burning carbon compounds.

An unnatural temperature increase in the atmosphere near earths surface is called what?
An unnatural temperature increase in the atmosphere near the Earth's surface is called global warming
What has caused Carbon Dioxide levels to steadily increase since the 1800s?
The burning of fossil fuels (coal & oil) is the primary cause of the increase in carbon dioxide levels 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.
What is the increase of carbon dioxide in the atmosphere the biggest contributor to?
An increase in the atmospheric levels of carbon dioxide is the biggest contributor to global warming.
How do producers affect the carbon cycle in earths atmosphere?
Producers, such as plants, remove carbon dioxide from the atmosphere during photosynthesis, converting it into organic carbon. This helps regulate the amount of carbon dioxide in the atmosphere. However, deforestation and land-use changes can release stored carbon back into the atmosphere, contributing to an increase in carbon dioxide levels and impacting the carbon cycle.
If more heat is trapped in the atmosphere how will the earths temperaturr change ?
If more heat is trapped in the atmosphere, the Earth's temperature will increase, leading to global warming. This can result in more extreme weather events, rising sea levels, and disruptions to ecosystems and wildlife. It is crucial to reduce greenhouse gas emissions to mitigate these effects.
