The first organisms to significantly change Earth's atmosphere were cyanobacteria, which emerged around 2.4 billion years ago. Through the process of photosynthesis, they produced oxygen as a byproduct, leading to the Great Oxidation Event. This increase in atmospheric oxygen transformed the planet's environment, paving the way for the evolution of aerobic life forms.

What was the first organism that released oxygen into the earths atmosphere?
The first organisms that released oxygen into Earth's atmosphere were cyanobacteria, also known as blue-green algae. These microorganisms performed photosynthesis, using sunlight to convert carbon dioxide and water into glucose and oxygen. This process began approximately 2.4 billion years ago during the Great Oxygenation Event, fundamentally changing the planet's atmosphere and paving the way for the evolution of aerobic life forms.
What was the first ever man made object to leave the earths atmosphere?
The first man-made object to leave Earth's atmosphere was the V-2 rocket launched by Germany on October 3, 1942.
Why is the earths surface not covered by the same impact craters?
First, we have a nice thick atmosphere that deals with many meteors. Secondly, weathering and erosion erase the marks fairly quickly.

How did astronaut john glenn describe his re-entry into earths atmosphere after being the first man to orbit the earth?
Astronaut John Glenn described his re-entry as feeling like a meteor in the Earth's atmosphere. He said it was a fiery experience with the heat shield glowing bright outside the capsule. Glenn compared it to being in a very long sunset.
Earths atmosphere was first changed by?
photosynthesis
How was earths early atmosphere first changed?
Earth's early atmosphere was first changed through volcanic activity, which released gases such as water vapor, carbon dioxide, and nitrogen. This led to the formation of oceans and the gradual accumulation of oxygen through photosynthesis by early organisms like cyanobacteria. This oxygenation process transformed the atmosphere to one more similar to the one we have today.
The first Indian Satellite aryabhatta was launched from?
the earths atmosphere
The first layer of earths atmosphere touching the earth?
troposphere
What was most abundant gas in the earths first atmosphere?
According to the Bible in its first Book called Genesis, you can read the following in Genesis 1: 2 " The earth was formless and desolated, and there was darkness upon the surface of the watery deep. Genesis 1: 1-30 explains in which order everything was created. Genesis 2: 6 speaks about a mist that would go up from earth, and it watered the entire surface of the ground. Humans and animals breathe in oxygen, give off carbon dioxide. Plants take in carbon dioxide give off oxygen . According to Genesis 1: 17 God made the expanse of the heavens to shine upon the earth. In photosynthesis plants use sunlight. carbon dioxide, water and minerals to produce oxygen and food products. Today we know that the most abundant gas in the earth is 78% Nitrogen, 21% Oxygen 1% all other gases. Some gases would be deadly by themselves, but mixed together in the atmosphere they sustain life. The sky is a miraculous achievement. Without water, animal and plants could not get the nutrients they need. The earth bears the unmistakable stamp of deliberate design, and there is no design without a designer. The Bible has this to say in Hebrew 3: 4. " Every house is constructed by someone, but he that constructed all things is God".
Who was the first to prove comets lie beyond earths atmosphere?
TyCHO BRACHE

Can the troposphere layer be considered as earths first protective layer?
Actually, the Troposphere Layer can be considered as Earth's first protective layer, because its well-the atmosphere's first layer. You can think of it that way to remember which is Earths first layer.
The first layer of the earths atmosphere touching earths surf?
The first layer of the Earth's atmosphere is called the troposphere, and it is in direct contact with the Earth's surface. This layer is where weather events occur and where most of the Earth's clouds and precipitation are found. Temperature usually decreases with altitude in the troposphere.
What are three ways in which the atmosphere is important to earth?
first of all it helps by : 1. the atmosphere gives earths animals or creations air to breath 2. the atmosphere helps plants grow 3.
What happened to the first American space station in 1979?
