Scientists believe that stromatolites were responsible for providing an oxygen-rich atmosphere in precambrian times. Stromatolites are structures formed of sediment. The cyanobacteria that formed these structures were photoautotrophs that used sunlight, carbon dioxide and water to produce their food and a byproduct of oxygen.
What else can I help you with?
When scientists talk about convection in the atmosphere they usually mean?
When scientists talk about convection in the atmosphere, they usually mean the upward movement of air due to differences in temperature and density. This process plays a crucial role in the formation of weather systems and the redistribution of heat in the atmosphere.
What earth process helps remove carbon dioxide from the atmosphere?
The process of photosynthesis helps remove carbon dioxide from the atmosphere.
Water carbon and nitrogen are released back into the atmosphere during what?
Water vapor is released back into the atmosphere through the process of evaporation. Carbon is released back into the atmosphere through the process of respiration and combustion. Nitrogen is released back into the atmosphere through the process of nitrogen fixation by bacteria.
What process adds and removes gases from the atmosphere?
The process that adds gases to the atmosphere is volcanic activity, which releases gases such as carbon dioxide and sulfur dioxide. The process that removes gases from the atmosphere is photosynthesis, where plants absorb carbon dioxide and release oxygen.
What are the seven science process skills scientists use?
The seven science process skills that scientists use are classifying, observing, measuring, inferring and predicting, communicating, and experimenting. Those are the seven science process skills scientists use
What is provided to scientists during the process of peer review?
constructive feedback
Which process do scientists think provided earth with an oxygen-rich atmosphere?
Scientists believe that the process of photosynthesis played a crucial role in providing Earth with an oxygen-rich atmosphere. This process, primarily carried out by cyanobacteria and later by plants, began around 2.4 billion years ago during the Great Oxidation Event. As these organisms converted carbon dioxide and water into glucose and oxygen using sunlight, the accumulation of oxygen in the atmosphere significantly transformed Earth's environment, enabling the evolution of aerobic life forms.
What is the process by which scientists grades the work of other scientists before it is published?
This process is called peer review.
What is the name of the lower layer of the earth's atmosphere?
Troposphere.Another AnswerThere is another layer that most atmospheric scientists and meteorologists may not agree with, but most biologists would, and that is the biosphere. It is the part of the atmosphere that participates in the respiration process of plants and animals, and it contributes to the earth's atmosphere in a subtle, yet dramatic, way.
When scientists talk about convection in the atmosphere they usually mean?
When scientists talk about convection in the atmosphere, they usually mean the upward movement of air due to differences in temperature and density. This process plays a crucial role in the formation of weather systems and the redistribution of heat in the atmosphere.
Explain why scientists might use models represent earths process?
why scientists use models to represent earths process
The process of decay releases carbon dioxide into the atmosphere?
The process of decay releases carbon dioxide into the atmosphere
What is the process that cleans the atmosphere?
This process is referred to as metalicphis, meaning "purify" in Latin. This is the process used to exterminate the spreading of germs within the atmosphere.
What is the process by which scientists 'grade' the work of other scientists befor it is published?
yes
What is the process by which scientist grade the process by which scientists before it is published?
yes
A process used by scientists to find answers to questions or solve a problem?
Is a process used by scientists to find answers to questions or solve a problem
What is the process called by which scientists check each other?
The process called by which scientists check each others work is known as Peer Review.
