None of the 4 gas giants (Jupiter, Saturn, Uranus, Neptune) have Earth-like solid surfaces on their exteriors, but rather deep, very dense atmospheres.
Of the four terrestrial planets (Mercury, Venus, Earth, Mars) Mercury is the only one without a substantial atmosphere, or current vulcanism, and has a pitted, cratered surface.

What can people do to decrease erosion of the earths surface?
The inner planets are different from the other planets mainly because
Which planets surface gravity is 38 percent that of earths?
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
How does gravity affect the earths surface?
It makes things weigh more or less, depending on the surface gravity.
What feature separates the rocky planets from the gas planets?
Depth of the atmosphere. Gas planets have the thickest and largest of atmospheres. Below gas planets atmospheres are pools of hydrogen or in some cases volatile ices that form in a giant ocean above the surface. It's estimated that Jupiter's rocky surface is only about the size of three Earths but the bloated atmosphere makes for most of the planet.
Why are there are almost no extrusive ultra basic rocks in earths crust?
There are almost no extrusive rocks on the earths surface because they are all under the earths surface. They are mainly lower than the earths surface.
What can people do to decrease erosion of the earths surface?
The inner planets are different from the other planets mainly because
Why are the craters on earths surface less evident than those on other terrestial planets surfaces?
The earth has an atmosphere which produces weathering of the land surfaces. Weathering gradually wears down features such as crater rims so the craters gradually become less evident and eventually disappear.
What planets air pressure is the same as it is 30 km above earths surface?
mars
Which planets surface gravity is 38 percent that of earths?
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
What do the the outer planets have in common?
They are all gas planets. They are all quite large and made from gas, so there is no real surface like that of earths.
Earths surfaces are also affected by many types of?
Earth's surfaces are affected by many types of movements and changes. The main effect on earth surfaces is caused by the movement of plate tectonics below the surface of the earth.
Why do the poles receive the less solar energy than the equator does?
Because the middle of the earths surface is the hottest on earth and the equator is right in the middle and the poles is at the end of the earths surfaces
Which rocky planet has the strongest gravitational pull?
Of the four inner, rocky planets, Earth is the largest and most massive. As a consequence, it has the highest surface gravity of the four inner planets. The gravity for Venus is around 90% of Earths, while for Mars and Mercury the surface gravity is around 38% of Earths.
What planets gravity is one-fourth the gravity of earth?
Of the planets in our solar system, Mars has the lowest surface gravity of around 38% of earths - over one third. This comes closest to the 25%. We then have moons and dwarf planets, but these have much lower surface gravities.
Which planets have a surface gravity greater than earths?
All 4 gas giants : Jupiter, Saturn, Uranus, Neptune.
Where is earths surface heated more south pole or north pole?
it is different in different points of the year.
What percent of the earths surface is the US?
100
