What else can I help you with?
Do all inner planets have thick atmospheres?
No. Only Venus has a really thick atmosphere. Mars has only a thin atmosphere and Mercury has almost no atmosphere.
Which 2 inner planets have thick atmospheres?
Venus and Earth are the two inner planets with thick atmospheres. Venus has a thick atmosphere composed mainly of carbon dioxide, while Earth has a diverse atmosphere containing nitrogen, oxygen, and other trace gases.
What does the atmosphere do for the inner planets?
It protects the inner planets from ultraviolet radiation
How do the inner and outer planets atmosphere different?
the outer planets are gaseous and the inner planets are not
How are inner planets and atmosphere different?
Inner planets, also known as terrestrial planets, are composed primarily of rock and metal, and include Mercury, Venus, Earth, and Mars. They generally have thinner atmospheres compared to outer planets, with Earth being the exception due to its relatively dense atmosphere that supports life. The atmospheres of inner planets can vary significantly; for instance, Venus has a thick, toxic atmosphere, while Mars has a very thin one. In contrast, outer planets are gas giants with thick atmospheres composed mainly of hydrogen and helium.
Why is the surface temperature of Venus higher than the other surface temperatures of the inner planets?
The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.
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.
Why is the surface temperature of Venus higher than the surface temperatures of the other inner?
The surface temperature of Venus is higher than the surface temperatures of the other inner planets because of its thick atmosphere.
What four inner planets has almost no atmosphere?
The four inner planets, also known as the terrestrial planets, are Mercury, Venus, Earth, and Mars. Among them, Mercury has almost no atmosphere due to its small size and proximity to the Sun, which causes any gases to escape easily. Mars has a thin atmosphere, primarily composed of carbon dioxide, but it is much less substantial than Earth's. Venus has a thick atmosphere, so it does not fit the criteria of having almost no atmosphere.
How are the inner planets protected from many asteroids strikes?
The atmosphere protects the inner planets the same way as for meteors.
Compare the atmospheres of the four inner planets?
Mercury has a thin atmosphere mostly made of oxygen, sodium, hydrogen, helium, and potassium. Venus has a thick atmosphere of carbon dioxide with clouds of sulfuric acid. Earth's atmosphere is primarily nitrogen and oxygen with traces of other gases. Mars has a thin atmosphere mainly comprised of carbon dioxide.
Of the inner planets What planet has the highest average temperatures?
Venus has the highest average temperatures of the inner planets, with surface temperatures that can exceed 860 degrees Fahrenheit (460 degrees Celsius) due to its thick atmosphere, greenhouse gases, and proximity to the Sun.
