What are two planets that are the same size but have widely different atmospheres and surface conditions?

If you are talking about in our own solar system, and not Exo-Planets, then Venus and Earth are of almost identical size and mass. The only thing is Venus has a toxic atmosphere and acid rain, with temperatures that would boil water. While Earth... Well, you know what Earth is like.

Why do all planets with and without atmospheres collide with meteoroids?
All planets, both with and without atmospheres, encounter meteoroids. If the planet has an atmosphere then those meteoroids will burn up long before reaching the surface. Those without atmospheres do not have such protection and so the meteoroids strike the surface directly.
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 do you think the planets look the way they look today?
They look like that because they are all at different distances and have different elements in their atmospheres. Mars looks red because we see the rocky red surface, while on the other planets (except Mercury) we only see the top of a very thick layer of clouds.
What are the properties for the solar system's planets?
the inner planets (Mercury, Venus, Earth, Mars) all have rocky solid surfaces. The outer planets (Jupiter, Saturn, Uranus, Neptune) all have gaseous atmospheres and liquid surfaces. Pluto is very dense and has a rocky surface.
How thin is the atmosphere?
It thickness or thinness is measured by the molecular weight and the surface pressure. The average molecular weight is about 28 and the pressure is 15 lb/sq.in. That can be compared with atmospheres on other planets e.g. Venus, Mars and all the outer planets.
Why do Jovian planets have a thicker atmosphere than the terrestrial planets?
Jovian planets do not have a solid surface, therefore their atmospheres are thick all the say to where their surface would be. Their atmospheres have more gasses than those surrounding terrestrial planets.

What do you call the four outer planets in our solar system?
They are called the "outer planets." But also the "gas giants" because they all have thick atmospheres and no accessible surface.
Why do planets with atmospheres have less impacts?
The atmosphere causes the object that is impacting or hitting the earth and causes it to burn and deteriorate as it lands on the earth's Surface.

Where can a meteors be found?
Meteors can only be found within the atmospheres of planets. If they are on the outside the atmosphere they are called Meteroids. And if they have already penetrated the surface of a planet they are called Meteorites.

What can people do to decrease erosion of the earths surface?
The inner planets are different from the other planets mainly because
How is the earth surface different from the other inner planets?
In a word : "water".
Why are the inner planets different to the outer planets?
The inner planets are all considered rocky planets in that under atmospheric layers, they have a rocky surface. The outer planets are made of gas and liquid, and are called gas giants. They have no solid surface. Also, all the outer planets have rings while the inner planets do not.
