What is the mechanism that keeps oxygen on Earth?
The mechanism that keeps oxygen on Earth is photosynthesis, a process where plants and other organisms convert carbon dioxide and sunlight into oxygen. This process helps maintain the balance of oxygen in the atmosphere, allowing living organisms to breathe and survive.
Molecules of hydrogen escape from earth but molecules of oxygen and nitrogen are held to the surface why?
Hydrogen molecules are very light and have high velocities, which allows them to reach escape velocity and escape Earth's gravitational pull. On the other hand, oxygen and nitrogen molecules are heavier and have lower velocities, so they are more likely to be retained by Earth's gravity and stay within the atmosphere. Additionally, the interactions and composition of Earth's atmosphere play a role in retaining oxygen and nitrogen compared to hydrogen.
Why is the Earths atmosphere needed for life?
The Earth's atmosphere is necessary for life because it contains oxygen for respiration, regulates temperature, protects against harmful rays from the sun, and provides the air we breathe. Without the atmosphere, conditions on Earth would be too extreme for life to exist.
What is the largest force that keeps the earth circling the sun?
The largest force that keeps the Earth circling the sun is gravity. Gravity is the force of attraction between the Earth and the sun that keeps the Earth in its orbit.
Why on Earth got atmosphere?
Earth has an atmosphere because gravity keeps gases from escaping into space. The atmosphere helps regulate temperature, protects against harmful radiation from the sun, and provides the oxygen needed for life to exist.
What is the mechanism that keeps oxygen on Earth?
The mechanism that keeps oxygen on Earth is photosynthesis, a process where plants and other organisms convert carbon dioxide and sunlight into oxygen. This process helps maintain the balance of oxygen in the atmosphere, allowing living organisms to breathe and survive.
Could you survive on Earth without the atmosphere?
No, because the atmosphere keeps in all the oxygen. Without the atmosphere the oxygen would escape.
How is water crucial to the earth?
water keeps the plant alive which produce oxygen for us to breathe wihtout water everyoneone on Earth will die
Do volcanoes have oxygen?
No. A volcano erupts molten material from inside the earth. Actual fire is not involved:the material is hot to begin with and has been since the formation of the earth.
Is gravity oxygen?
No, gravity is not oxygen. Gravity is the force that pulls objects toward each other, while oxygen is a chemical element that is essential for life and makes up a large portion of the Earth's atmosphere.
Which layer of atmosphere keeps in oxygen?
The troposphere is the layer of the atmosphere that contains the highest concentration of oxygen and is where most weather occurs. This layer extends from the Earth's surface up to around 10-15 kilometers in altitude.
Molecules of hydrogen escape from earth but molecules of oxygen and nitrogen are held to the surface why?
Hydrogen molecules are very light and have high velocities, which allows them to reach escape velocity and escape Earth's gravitational pull. On the other hand, oxygen and nitrogen molecules are heavier and have lower velocities, so they are more likely to be retained by Earth's gravity and stay within the atmosphere. Additionally, the interactions and composition of Earth's atmosphere play a role in retaining oxygen and nitrogen compared to hydrogen.
How does the atmosphere keep oxygen inside?
Inside what? Oxygen is part of the atmosphere. The thermal velocity of its molecules are insufficient to escape earth's gravity (unlike hydrogen molecules which are fast enough).
Why is the Earths atmosphere needed for life?
The Earth's atmosphere is necessary for life because it contains oxygen for respiration, regulates temperature, protects against harmful rays from the sun, and provides the air we breathe. Without the atmosphere, conditions on Earth would be too extreme for life to exist.
Is oxygen in gravity?
No. Gravity is not a substance. It is an attractive force between objects with mass.
Why is the sun considered the most important part part of the earth's system?
because the sun is the only thing that keeps us alive. it keeps us from freezing ,helps plants grow ,which give us oxygen and keeps ecosystems running.
Why is the Earth's innermost layer a solid?
The immense pressure inside Earth keeps the inner core solid even though it is well above its normal melting temperature.
