How planet earth was able to maintain a very comprehensive atmosphere?

Because it has sufficient gravity and a strong magnetosphere.


If you can travel to a planet with an atmosphere like that of early earth would you be able to survive?

no


How is the size of the planet related to its thickness atmosphere?

There is no simple relationship, but the general tendency is that more massive planets have more gravitational attraction, and are able to maintain a denser atmosphere. The amount of atmosphere a planet has may also depend on it closeness to the Sun / to the planet's star, and to its evolutionary history.

Why was earth able to hang on its atmosphere?

Earth is able to retain its atmosphere due to its gravity. The gravitational force of Earth is strong enough to hold on to the gases of the atmosphere, preventing them from escaping into space. This creates a stable environment that allows for life to exist on the planet.


Will earth be different if the earth was half its mass?

It the earth was half its mass, then it might only be able to hold half the atmosphere. In this case, it may not be able to maintain many species of life as we know it.


How can you maintain oxygen in the atmosphere?

Well to maintain the oxygen in the earth atmosphere you need to make sure that the level of global warming is decreasing and less fumes will be able to make up the ozone layer. With a thinner layer around the earth this means that oxygen will be able to enter and exit the earths surface, allowing oxygen to still stay in the atmosphere.


Earth is the only planet able to support what?

Life. One reason for this is the fact that it has water and a breathable atmosphere.


The gas layer necessary for life because it provides the air we breathe?

The gas layer necessary for life is the atmosphere, which surrounds the Earth and provides the air we breathe. The atmosphere consists of various gases, including nitrogen, oxygen, and carbon dioxide, which are essential for supporting life on our planet. Without the atmosphere, Earth would not be able to maintain the right conditions for life to thrive.


What gas was needed to be established within the earths atmosphere before the atmosphere was able to absorb and maintain heat?

The gas needed to establish before the Earth's atmosphere could absorb and maintain heat was carbon dioxide. This gas, along with other greenhouse gases like methane and water vapor, trap heat in the atmosphere and help regulate the Earth's temperature.


Can the Earth rotate without gravity?

Yes, the Earth can rotate without gravity, as rotation is a result of angular momentum rather than gravitational forces. However, gravity is essential for maintaining the planet's shape and keeping everything, including the atmosphere, anchored to its surface. Without gravity, the Earth would not be able to hold onto its atmosphere or maintain its structural integrity, leading to significant changes in its physical characteristics. Thus, while rotation can occur independently of gravity, the overall dynamics of the planet would be drastically altered.


Which is the only planet that is able to harbor life?

As far as we currently know, it is Earth. But earth may in fact not be the only planet able to harbor life. We have just begun looking.
