What else can I help you with?
What element upon which most modern organisms depend was missing from earth's early atmosphere?
Oxygen was the element missing from Earth's early atmosphere, which eventually accumulated due to early photosynthetic organisms. This change in the atmosphere allowed for the evolution of organisms that rely on oxygen for respiration.
Are there living organisms on Pluto?
It is highly unlikely that there are living organisms on Pluto due to its extreme cold temperatures and lack of a substantial atmosphere. The surface conditions on Pluto make it inhospitable for life as we know it.
Which of earth layers does radiation occur?
Radiation can occur in all layers of the Earth, but it has the greatest impact on the Earth's surface due to interactions with the atmosphere and the geomagnetic field. Cosmic radiation from space can penetrate the atmosphere and reach the Earth's surface, affecting living organisms and materials.
Can the water cycle proceed if there were no living organisms?
Yes, the water cycle can still proceed without living organisms. The cycle involves processes like evaporation, condensation, and precipitation, which occur due to physical and chemical interactions in the environment. While living organisms play roles in some aspects of the cycle, such as transpiration, the fundamental processes of water movement through the atmosphere, land, and bodies of water would continue independently of life.
When organisms began using photosynthesis what gas was added to the atmosphere as a result?
Oxygen is one of the products of photosynthesis and is the gas that rose in abundance in the atmosphere due to the process of photosynthesis.

What caused a major change in the composition of Earths atmosphere?
One major change in the composition of Earth's atmosphere was the Great Oxidation Event about 2.4 billion years ago. This event led to a significant increase in oxygen levels due to the emergence of photosynthetic organisms that released oxygen as a byproduct. This change had a profound impact on the evolution of life on Earth.
Does the pH of a solution change over time?
Yes, the pH of a solution can change over time due to various factors such as the addition of acids or bases, chemical reactions, or the presence of living organisms.

How does the atmosphere form?
The atmosphere forms through processes such as outgassing from volcanoes and the gradual accumulation of gases released from the Earth's interior. The early Earth's atmosphere was mainly composed of carbon dioxide and water vapor, with oxygen increasing over time due to photosynthetic organisms. The atmosphere continues to evolve through interactions with Earth's surface, living organisms, and external influences like solar radiation.
Why is earth's current atmosphere made up of nitrogen and oxygen?
Well just saying THE OZONE LAYER IS GETTING DESROYED i know i spelled that wrong So dont eef with the ozone layer
What factors are likely to change on earth due to a warming atmosphere?
dynasty
Why does amount of oxygen Change?
When you inhale, you get a greater amount of oxygen and when you exhale, your oxygen dicreases 25%
What is factual statement about carbon?
Carbon is a fundamental element that is essential for life on Earth, found in all living organisms. It has the ability to form a wide variety of compounds due to its versatile bonding properties, making it crucial for the structure and function of biological molecules. Carbon plays a key role in the carbon cycle, where it is transferred between the atmosphere, oceans, and living organisms.
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.
