Why do the inner and outer planets have different compositions?
A planet's density is related to its composition. The four inner terrestrial planets are dense compared to the four outer planets. The inner planets are made up mainly of dense, solid rock. The outer planets are composed primarily of gas, so their overall density is lower.
How did the compositional differences between the outer and inner planets originate choose 2?
Why do the giant planets and their moons have compositions different from those of the terrestrial planets? The high temperatures of the inner solar system did not allow for condensation of the volatile materials found in the outer solar system.
What is the difference between the inner and outer planets?
Summary. The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
Why are the outer planets and inner planets different?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
What is difference between inner and outer planets?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
What is the composition of the inner planets?
Composition of Inner Planets The inner planets are composed of silicates and metals. Their crusts and mantles are made of refractory minerals or silicates, while their cores are made of iron and nickel, and all of them have valleys and volcanoes on their surfaces. Most of the inner planets have atmospheres and weather.
What is the difference between inner space and outer space?
Abstract. In popular psychology, inner space refers to thoughts, imagery, dreams, attitudes, and feelings, while outer space refers to the external environment.
What do inner planets have that outer planets don t?
There are a few important observations: 1) The “inner planets” (Mercury, Venus, Earth, Mars) don't have rings and all of the “outer planets” (Jupiter, Saturn, Uranus, and Neptune) do. 2) The outer planets are much more massive than the inner planets.
What is the composition of outer planets?
) In contrast, the four outer planets, also called the Jovian, or giant, planets—Jupiter, Saturn, Uranus, and Neptune—are large objects with densities less than 2 grams per cubic cm; they are composed primarily of hydrogen and helium (Jupiter and Saturn) or of ice, rock, hydrogen, and helium (Uranus and Neptune).…
What are the two groups of planets based on composition Part 2 describe the composition of each group?
Planets are generally divided into two groups: the terrestrial and the giant planets. The terrestrial planets are the four inner planets: Mercury, Venus, Earth, and Mars. They are generally small in size (about the size of the Earth) and are predominantly rocky in composition.
What does outer space smell like?
A succession of astronauts have described the smell as '… a rather pleasant metallic sensation … (like) … sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.
Does space ever end?
No, they don't believe there's an end to space. However, we can only see a certain volume of all that's out there. Since the universe is 13.8 billion years old, light from a galaxy more than 13.8 billion light-years away hasn't had time to reach us yet, so we have no way of knowing such a galaxy exists.
What is the major difference between the inner and outer planets?
In our Solar System, astronomers often divide the planets into two groups — the inner planets and the outer planets. The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas.
What is the difference of inner and outer planets?
Mercury, Venus, Earth, and Mars are the planets closest to the Sun. They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune.
What is the composition of the inner planet?
The inner planets are composed of silicates and metals. Their crusts and mantles are made of refractory minerals or silicates, while their cores are made of iron and nickel, and all of them have valleys and volcanoes on their surfaces. Most of the inner planets have atmospheres and weather. (However, Mercury does not.)
What is the major difference between the inner and outer planets of the solar system?
The inner planets are closer to the Sun and are smaller and rockier. The outer planets are further away, larger and made up mostly of gas. The inner planets (in order of distance from the sun, closest to furthest) are Mercury, Venus, Earth and Mars.
Why are the inner planets different from the outer planets?
Outer planets are composed of lighter elements such as gases and inner planets are composed of heavy elements such as iron. Inner planets have fewer moons, small, silicate surface, nickel-iron core, higher density and rotate more slowly compared to outer planets.
Can u fart in space?
On Earth, farts are typically no big deal — smelly, harmless, and they quickly dissipate. But if you're an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.
What kills you in space?
REAL SPOILER ALERT: The short answer is that the lack of oxygen would make you black out after about 15 seconds. Then by about 90 seconds you are too far gone to be saved. So you would die from lack of oxygen well before the radiation and cold would have time to kill you.
Is there color in space?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.
Does space have a smell?
We can't smell space directly, because our noses don't work in a vacuum. But astronauts aboard the ISS have reported that they notice a metallic aroma – like the smell of welding fumes – on the surface of their spacesuits once the airlock has re-pressurised.
What are the two groups of planets based on composition?
Planets are generally divided into two groups: the terrestrial and the giant planets. The terrestrial planets are the four inner planets: Mercury, Venus, Earth, and Mars. They are generally small in size (about the size of the Earth) and are predominantly rocky in composition.
Who was the first person to fart on the moon?
astronaut John Young American astronaut John Young, 87, died on Saturday, after a career of many firsts: first man to fly in space six times, pilot of the first Gemini mission, commander of the first shuttle flight, and humorously, becoming the first man to fart on the moon.
Can you bottle a fart?
2:143:47How to catch your farts in a jar: Gastronaut – YouTubeYouTube
Has anyone been lost in space?
Fatal space travel disasters. As of the beginning of 2022, there have been five fatal incidents during space flights, in which 19 astronauts were lost in space and four more astronauts died on Earth in preparation for the flight.
Would your eyes pop out in space?
NASA makes it clear that your body wouldn't explode and your eyes wouldn't pop out of your head like many science fiction movies suggest. However, you would swell up and get really painfully puffy. Even while you're floating there unconscious and puffy, your troubles aren't over.
What’s the ugliest colour?
drab dark brown Pantone 448 C is a colour in the Pantone colour system. Described as a "drab dark brown" and informally dubbed the "ugliest colour in the world", it was selected in 2012 as the colour for plain tobacco and cigarette packaging in Australia, after market researchers determined that it was the least attractive colour.
Is black a color?
And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they're shades. They augment colors.
Do you age in space?
In space, people usually experience environmental stressors like microgravity, cosmic radiation, and social isolation, which can all impact aging. Studies on long-term space travel often measure aging biomarkers such as telomere length and heartbeat rates, not epigenetic aging.
Did anyone pee on the moon?
Fifty years after men walked on the moon, it's time to talk about peeing in space. Buzz Aldrin was the first man to pee on the moon.
