We know that Mercury has very minute quantities of hydrogen, helium, etc. But the solar wind on Mercury is strong that it does not allow the Atmosphere to get thicker there. Thus there isn't any atmosphere on the sun-facing side, but there is an Atmosphere on the non-sun facing side.
What else can I help you with?
What does dense atmosphere mean?
Thick air. Planets like Venus, Jupiter, Saturn, Neptune and Uranus have a very dense atmosphere.
Why are the Jovian planets so much larger than the terrestrial planets?
Jovian planets are larger because they are primarily composed of gases such as hydrogen and helium, which are less dense than the rocky materials that make up terrestrial planets. This allows them to accumulate more mass and grow to much larger sizes. Additionally, their greater distance from the Sun allowed them to retain more of their original gaseous material during the formation of the solar system.
What part of the rain forest is very dense?
Most of the rainforest is very dense, but the understory and canopy are both pretty dense. The canopy and the understory are both very dense but the undersrory is the most dense.
Does a planet's distance from the sun affect it's density?
Very generally, the outer four planets are less dense than the four inner rocky planets, but it's more to do with planet type rather than their distance from the sun.
Are the outer planets are much less dense than the inner planets why?
The outer planets. The four inner planets (Mercury, Venus, Earth, Mars) are similar to Earth - relatively small, and with a rocky surface. The four outer planets (Jupiter, Saturn, Uranos, Neptune) are gas giants - between 5 and 11 times the diameter of Earth, and made up mainly of gas. They don't have a solid surface you can step on - just gas that gets denser as you go deeper inside.
What is the most obvious difference between the terrestrial and the Jovian planets?
The greatest difference is in their size. Gas giants are large but have a very low average density (much of their size includes their atmospheres). From a physical standpoint, terrestrial (rocky) planets have a solid exterior surface. Jovian (gas giant) planets instead exhibit a smooth range of increasing density, and do not have the abrupt change to solidity that terrestrial planets exhibit.
Is the inner core not very dense?
The inner core is very dense. It is the densest part of the planet.
What is the difference between Jovian and Terrestrial planets?
Jovian planets (gas giants, ice giants) are composed of gas, mainly hydrogen and helium. They have a solid core of rocks and ice about Earth's size, around which is a dense atmosphere of gas, including liquid gases, or even solid hydrogen in the case of Jupiter. Jupiter, Saturn, Uranus and Neptune are Jovian planets. Although their slushy outer cores are very hot and dense, Uranus and Neptune are referred to as "ice giants."Terrestrial planets are much smaller, with dense metal cores, a solid crust as a surface, and comparatively thin atmospheres. In the case of Mercury, the atmosphere is blown away by the solar wind, but for Venus is it much more dense than on Earth. The terrestrial planets are Mercury, Venus, Earth and Mars.jovian planets are rocky and terrestrial planets are gasy
Is very salty water more or less dense than more dense?
More Dense.
What is the difference between terrestial planets and gas planets?
The terrestrial planets are small in size and mass, they are rocky, solid and dense, all four terrestrial planets have 3 moons between them. They are warm and close to the sun. Terrestrial planets USUALLY have thin atmosphere. The Gas Giants are huge in size, have rings made from dust, debris, ice, rock. They very cold (not close to the sun at all) and light (made from gas.) They have several moons between them (167, I think) and lastly Gas Giants usually have thick and deep atmosphere.
Why are the inner planets dense and small while the outer planets are gas giants?
Gas Giants have mostly Hydrogen gas which is the lightest element, so in fact gas giants are in overall density the lightest of all the planets. Jupiter is 318 times the mass of the whole Earth, and roughly 99% of that mass is Hydrogen. At their cores they may be very dense because of great pressure, but it is still mostly Hydrogen and not as dense as a rocky planet. Gas Giant densities may be very different from each other because along with the Hydrogen they may have more Helium or a larger core of ice and/or rock. Neptune's overall density is 1.638 g/cm³ - 30% as dense as Earth Jupiter's overall density is 1.326 g/cm³ - 24% as dense as Earth Uranus's overall density is 1.27 g/cm³ - 23% as dense as Earth Saturn's overall density is 0.687 g/cm³ - 12% as dense as Earth Earth's overall density is 5.515 g/cm3
Is the population more dense around the Danube river?
Yes, it is very dense.
