How do the escape velocities of the jovian planets compare to the terrestrial planets?
The Jovian planets have much higher escape velocities.
Suggest how gases escape from the Earth's crust?
Thermal energy causes some of the molecules at the outer edge of the Earth's atmosphere have their velocity increased to the point where they can escape from the planets gravity. T;)
If the composition of the upper atmosphere were changed so that it permitted terrestrial radiation to escape what effect would this have on earth's climate?
The escaping heat would mean that the Earth would freeze.
Is the escape velocity of hydrogen at mars more than it's gravity or in other words can hydrogen in gaseous state exist on the planet mars?
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
Why do different planets have different atmospheres?
All the sun's planets probably had similar atmospheres when they first formed, billions of years ago. The most common gases were the light gases, hydrogen and helium, with smaller amounts of oxygen, nitrogen and other gases. The immense gravity of the giant planets, Jupiter, Saturn, Uranus and Neptune, was able to hold the hydrogen and helium, which remain the predominant gases in their atmospheres, along with methane formed by the combination of hydrogen with free carbon. However, hydrogen and helium gradually escaped from the atmospheres of the smaller planets, where gravity is insufficient to hold the light gases permanently. Even the heavier gases, such as oxygen and nitrogen, as well as carbon dioxide and water vapour, can gradually escape from smaller planets, such as Mars and Mercury. So, these planets now have quite thin atmospheres. The Moon and other small bodies in the solar system have essentially no atmosphere. In our solar system, only the Earth and Venus are the right size to lose most of the light gases, while retaining gases such as oxygen, nitrogen, carbon dioxide and water vapour.
Which process explains why the terrestrial planets do not have hydrogen and helium in their atmospheres?
The terrestrial planets are less massive and therefore have less gravity. As a result, much of the lighter gases could escape, in the process of planet formation.
How do the escape velocities of the jovian planets compare to the terrestrial planets?
The Jovian planets have much higher escape velocities.
Why is it more difficult for gases to escape from Jovian planets than terrestrial planets?
Jovian planets have a much stronger gravitational force due to their larger mass.
Why is hydrogen so rare in the atmosphere?
Hydrogen is rare in the atmosphere because it is light enough to escape Earth's gravitational attraction.
The atmosphere of the gas giant planets cannot escape into space because?
the planets have very strong gravitational pulls.
Why can gases such as helium escape earth's atmosphere?
Helium can escape because it is the least dense element after Hydrogen.
Why doesn't the atmosphere of the giant planets escape into space?
Gas particles (atoms, molecules) composing the atmosphere of a planet have a mass, therefore they are trapped by the gravitational field of the planet. This is not only true for giant planets but applies to all planets with atmosphere.
Why can't the atmosphere of gas giant planets escape into space?
Where a planet or moon has an atmosphere, it is the gravity of the moon or planet that holds the atmosphere on the planet or moon.
The suns energy enables what from the waters surface to escape into the atmosphere?
Water condensation. Oxygen and Hydrogen.
Why doesn't the atmosphere of the gas giants escape into space?
Gas particles (atoms, molecules) composing the atmosphere of a planet have a mass, therefore they are trapped by the gravitational field of the planet. This is not only true for giant planets but applies to all planets with atmosphere.
What is the outer most region of a planets atmosphere in which the density is low enough that the lighter atmospheric atoms can escape into space?
The Exosphere
Suggest how gases escape from the Earth's crust?
Thermal energy causes some of the molecules at the outer edge of the Earth's atmosphere have their velocity increased to the point where they can escape from the planets gravity. T;)
