What else can I help you with?
Are the outer planets lighter than the inner planets?
No, the outer planets are not lighter than the inner planets. In fact, the outer planets are generally much larger and more massive than the inner planets. This is because they are primarily composed of gases and ice, which makes them less dense but more massive.
Are the outer planets made of gases?
YES
What keeps the gases of outer planets from escaping?
The planet's strong force of gravity holds the atmosphere down and stops it escaping. Atmospheric gases have masses, and the Earth's atmosphere has a mass of about 1.2 kg per cubic metre.
Are the inner planets warmer than the outer planets?
No, the inner planets are not necessarily warmer than the outer planets. While the inner planets are closer to the Sun and therefore receive more sunlight, factors such as atmosphere composition, greenhouse gases, and internal heat sources can also impact a planet's temperature. For example, Venus, the second planet from the Sun, is hotter than Mercury, which is closest to the Sun, due to its thick atmosphere trapping heat.
Do any outer planets have the greenhouse effect?
Yes, outer planets like Jupiter and Saturn have the greenhouse effect, but it is not as significant as on Earth due to their different compositions and much larger distances from the Sun. These planets have thick atmospheres with gases that trap heat, contributing to their overall temperatures.
Are the outer planets lighter than the inner planets?
No, the outer planets are not lighter than the inner planets. In fact, the outer planets are generally much larger and more massive than the inner planets. This is because they are primarily composed of gases and ice, which makes them less dense but more massive.
Why is the atmosphere thick in the outer planets?
The outer planets have thick atmospheres because they are so big. The bigger the planet, the stronger the gravitational pull. This means that the bigger planets pull in more gasses, which creates a bigger, thicker atmosphere.
Did outer planets lose the light gases in their atmosphere?
Yes, outer planets like Jupiter and Saturn likely lost light gases from their atmospheres due to their gravity not being strong enough to retain these gases. Additionally, the strong solar wind and radiation in the outer solar system may have contributed to the loss of these gases over time.
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
How do the inner and outer planets atmosphere different?
the outer planets are gaseous and the inner planets are not
Are the inner and outer planets different?
The inner planets are all rocky planets. The outer planets are completely made up of gases. The inner planets are much smaller than the outer planets.
Are the outer planets made of gases?
YES
Why do the outer planets still have an atmosphere?
Because gases exist even at great distances from the sun. Also the large gas planets have internal heating sources emitting from their core.
What keeps the gases of outer planets from escaping?
The planet's strong force of gravity holds the atmosphere down and stops it escaping. Atmospheric gases have masses, and the Earth's atmosphere has a mass of about 1.2 kg per cubic metre.
Could you land on the outer planets?
No. The outer planets do not have solid surfaces. Those planets are made of gases held together by gravity.
Why do inner planets have thinner atmospheres than the outer planets?
An atmosphere is a layer of gas that surrounds a planet; this gas is attracted by gravity and is greater in volume depending on the strength of the gravitational field and the temperature of the atmosphere. The inner planets generally have less mass, resulting in a less strong gravitational field, and a warmer atmosphere meaning the atmosphere is thinner than the colder, larger outer planets.
How do the inner planets diffrer from the outer planets?
the inner planets made up of rocks while the outer planets are made up of gases and liquids.
