What is the envelope of gases that surrounds a planet like earth?
The envelope of gases that surrounds a planet like Earth is called the atmosphere. It is composed of layers of gases that are held in place by the planet's gravity, providing vital protection and support for life as we know it. The atmosphere plays a crucial role in regulating temperature, protecting against harmful radiation, and facilitating weather patterns.
What does astmosphere mean?
The atmosphere is the layers of gases surrounding a planet or celestial body, held in place by gravity. On Earth, the atmosphere plays a crucial role in regulating temperature, protecting life from harmful radiation, and supporting weather patterns.
What planet is Its atmosphere is mostly nitrogen?
Planet Earth - about 80%.
What does the gravity do to the atmosphere?
Answer: It keeps up from being crushed from the atmosphere around us... it also keeps us from floating away and helps keep the earth the right temp. Answer: Gravity keeps the atmosphere around the planet in the first place.
What planet has stronger or weaker gravity than earth?
All of them do. There's no planet where the gravity is the same as on Earth.
Why is space not like earth?
Earth: Space: - is a planet - No gravity - supports life - Vaccum - gravity - No gravity or atmosphere - atmosphere
Why is the atmosphere above the surface of the earth?
The atmosphere is above the surface of the Earth because gravity pulls it towards the planet. The atmosphere contains gases that are essential for life, such as oxygen and nitrogen, and it helps regulate the planet's temperature by trapping heat from the sun.
Why the planet earth was able to maintain its atmosphere?
Gravity
What is the most nice planet in the universe?
Earth- since so far, it is the only planet that has a combination of gravity, temperature, water and atmosphere where people can live.
What keeps the atmosphere around the earth?
A magnetic field holds atmosphere to the planet. Without a magnetosphere the solar wind from the sun will blow the atmosphere away. That is why our planet still has an atmosphere, we have the magnetic poles.
Why do the gases in the earth atmosphere stay close to the surface of the planet?
Gases in the Earth's atmosphere stay close to the surface due to the force of gravity acting on them. Gravity pulls the gases towards the center of the planet, keeping them from escaping into space. The mass of the Earth is sufficient to maintain an atmosphere that surrounds the planet.
What is the atmosphere bound to the earth by?
The force of gravity binds the hydrosphere and lower atmosphere to earth.
What is earth's upper atmosphere?
The atmosphere of Earth is a layer of gases surrounding the planet Earth that is retained by Earth's gravity. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation).
The atmosphere is held in place by Earth's?
The atmosphere is held in place by Earth's gravity. Gravity keeps the gases of the atmosphere from drifting off into space and creates a force that pulls them towards the planet's surface. Without gravity, the atmosphere would dissipate into space.
What holds the Earth's atmosphere in place?
The atmosphere is held in place by the earth's gravity. Gravity is related to mass, the more mass a planet has, the more gravity. A much smaller planet like mercury or a body such as the moon will have less gravity, not enough to hold an atmosphere - the gravity is not strong enough to prevent the gas particles from escaping into space.
Explain how earth's mass is related to its ability to have an atmosphere?
The Earth has an atmosphere because it has the gravity necessary to keep the gases from floating off into space. The more mass a planet has, the more gravity it has, and the more gravity it has, the thicker an atmosphere it can sustain.
What planet contains a five layer atmosphere?
Earth contains a five layer atmosphere. It is due to gravity.
