How does carbon dating prove a young earth?
Carbon-dating can not be used to prove the age of the earth, so it can not be used either to prove a "young earth" nor to support the scientific age of the earth. Carbon-dating is useful for archaeology, where it can date evidence of human artefacts up to fifty thousand years old. Some less less informed "Young Earth" creationists do believe that carbon-dating was used to date the earth. They attempt, unsuccessfully, to undermine the science of carbon-dating in the belief that by doing so they undermine the scientific age of the earth, rather than because they constructively prove their point. The best estimates of the age of the earth have been arrived at by radioactive dating, but not by carbon-dating. Had techniques of radioactive dating not been invented, other known methods of dating the earth would prove that the world is more than a few million years old. Some of these are described in the related question, attached below.
Forest help reduce greenhouse effect by?
Forests are made up of trees and other plants. These use carbon dioxide (a greenhouse gas that is created by industry) and converts it into food and oxygen. The more forests there are the more carbon dioxide gets converted back into oxygen.Trees are tremendous devices for capturing and storing carbon. If we were to ask our top scientists and engineers to create a highly efficient and environmentally friendly way to remove carbon from the atmosphere. They could do no better than to invent a tree. Trees use photosynthesis to capture and concentrate carbon, removing trace CO2 gas from the air (
How was Venus born?
The atmosphere of Venus is made up mainly of carbon dioxide, and thick clouds of sulfuric acid completely cover the planet. The atmosphere traps the small amount of energy from the sun that does reach the surface along with the heat the planet itself releases. Thisgreenhouse effect has made the surface and lower atmosphere of Venus one of the hottest places in the solar system! If you were on the surface of the planet, the air above you would be about 90 times heavier than the Earth's atmosphere. This is like what a submarine experiences at 3000 ft below the surface of the Earth's ocean. The atmosphere is composed mainly of carbon dioxide (96%), 3.5% nitrogen, and less than 1% is made up of carbon monoxide, argon, sulfur dioxide, and water vapor.
What are the differences and similarities between Venus and Earth?
Similarities between Earth and Venus are - Similar in size Very few craters indicating a relatively young surface Density and chemical composition are similar Differences between Earth and Venus are - Venus has no moon Venus' surface temperature is about 400 degrees Celsius Venus' atmosphere is toxic to Earth based life Venus' atmospheric pressure at the surface is about 90 times greater than Earths Venus takes about 243 Earth days to complete one full turn on its own axis Venus takes about 224 Earth days to complete one full orbit of the Sun Scientists are considering the similarities and differences between Earth and Venus, to try to figure out Earth's fate.
Why couldn't ice core data be used when the earth was young?
no ice currently on earth is that old
Was there carbon dioxide in the air when the earth was young?
In the very young earth the atmos. was mostly carbon dioxide. This caused the earth to have a very warm atmosphere. There was no life at that time on earth. It was a few billion years ago.
Did cyanobacteria change the young Earth's atmosphere by producing carbon dioxide?
No, cyanobacteria helped change the young Earth's atmosphere by producing oxygen through photosynthesis. The accumulation of oxygen in the atmosphere eventually led to the Great Oxidation Event, around 2.4 billion years ago, which transformed the atmosphere to be more oxygen-rich.
Why does young crop take in less carbon dioxide?
The young crop has less leaf area and less chlorophyll than older crops. The leaves take in carbon dioxide for photosynthesis and use it to make carbohydrates.
Do young tree take up more carbon dioxide than old trees?
Young trees grow quicker than mature trees (mature trees reach their maximum size then stop growing taller) as a consequence the young trees are taking in carbon dioxide to make both wood and leaves, mature trees nly require the carbon dioxide for leaves. There is some change in the soil content of carbon sequestered in the soil at the base of the trees as well,
Why is planet earth the only planet with air?
It depends on how you define air. Other planets in the solar system have atmospheres, but they have different compositions from Earth's atmosphere, which may or may not be called air. The gas planets have atmospheres made mostly of hydrogen and helium while Venus and Mars have atmospheres made mostly of carbon dioxide. The air we are familiar with is mostly nitrogen and oxygen. When Earth was young it likely had a carbon dioxide atmosphere as well, but through photosynthesis algae took carbon dioxide out of the atmosphere are replaced it with oxygen. More carbon dioxide was removed in bodies of water and deposited as carbonate rocks. The nitrogen, already present in the atmosphere, remained.
What is the source of earths original atmosphere?
Earth's original atmosphere is believed to have been formed by outgassing from the planet's interior, which released gases such as water vapor, carbon dioxide, and nitrogen. These gases accumulated around the young Earth to create the primordial atmosphere.
What is best absorber of infrared radiation?
well, i believe Co2 (carbon dioxide) and H2o (water) are the best absorbers of infrared radiation my young grass hopper. Beast
How much co2 does a tree absorb per year?
Almost half the mass of a tree is carbon, taken from the atmosphere in the form of carbon dioxide. A tree only takes in carbon when it is growing, and the amount that a tree grows in a year varies from tree to tree. Old trees are bigger and grow more than young trees in a year, usually.

Why is photosynthesis so important to Earth atmosphere and Mankind?
The thing that makes photosynthesis so important to the earth and atmosphere and mankind is what we need to find this out for b-tech science. Myself, sian young, Lauren wray, Chelsea Robinson :)
What did the earth look like when it was young?
When the Earth was young, approximately 4.5 billion years ago, it was a molten mass of rock and metal, characterized by extreme volcanic activity and a hostile environment. The surface was primarily covered by magma oceans, with occasional landmasses emerging as the planet cooled. The atmosphere was thick with gases like carbon dioxide, ammonia, and water vapor, with little to no oxygen, making it inhospitable for life as we know it today. As the planet continued to cool, water began to accumulate, eventually forming the early oceans.
What is meant by earth surface is very young?
well it means that the earth is young it small
