What did Alexander Oparin say about the earth's early atmosphere?
Oparin believed that there was one molecule lightning strike and then the gases developed
Was there oxygen in the atmosphere of early earth?
Yes, there was very little to no oxygen in the atmosphere of early Earth. The atmosphere was primarily composed of gases like carbon dioxide, nitrogen, and water vapor. Oxygen levels began to rise significantly due to the evolution of photosynthetic organisms.
Which of these is not one of the primary gase found in earths atmosphere?
Helium is not one of the primary gases found in Earth's atmosphere. The primary gases in Earth's atmosphere are nitrogen, oxygen, argon, and carbon dioxide. Helium makes up a very small percentage of the atmosphere.
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.
What is the presence of toxic gases and other particles in the Earth's atmosphere?

What is the current situation of the earth's atmosphere?
Well in terms of Global Warming, the burning of fossil fuels (gas for cars is one) releases more greenhouse gases, which mean there are more greenhouse gases in the atmosphere. These gases reflect sunlight BACK towards earth, keeping it warm. So the more greenhouse gases means the earth is warmer.
What are the trapped gases in the atmosphere?
The major trapped gases in the Earth's atmosphere are carbon dioxide, methane, and nitrous oxide. These gases contribute to the greenhouse effect, trapping heat near the Earth's surface and leading to global warming and climate change.
Which of these is a component of the earths atmosphere?
these ??? There are no choices to choose from.
Why couldn't you have survived in the atmosphere of early earth?
Until plants formed there wouldn't have been enough oxygen. We need oxygen - even though there's only about one part of it in five parts of air. Plants take in carbon dioxide and give off oxygen.
What is one way that gases in earth's atmosphere protect the biosphere?
Gases in the Earth's atmosphere, such as ozone, absorb and scatter harmful ultraviolet (UV) radiation from the sun. This protects living organisms on Earth's surface from the damaging effects of excessive UV radiation, which can cause skin cancer and harm ecosystems.
When was the atmosphere first developed?
1 Did you ever wonder why there was no life when earth began? One reason is that there was no oxygen. Hydrogen and helium were the two gases that made up the earth's early atmosphere. 2 These elements have very small masses. Because of this, they escaped into space. Earth's gravity was not strong enough to hold onto them. The solar wind whipped them away. 3 So, how was our atmosphere formed? You have learned that when a volcano erupts, huge amounts of gases escape. This is called outgassing. 4 Much of this gas is water vapor. Carbon dioxide and nitrogen also erupt from volcanoes. Many scientists think the process of outgassing is what formed our early atmosphere.
