Describe the basic features of the condensation theory of the formation of the solar system. … After the solar nebula formed, cooled dust grains formed condensation nuclei around which matter began to accumulate. As they grew larger collisions and accumulation increased until fragmentation occurred and planets formed.
What is condensation in astronomy?
Condensation is the process of forming solid particles from the solar nebula, whereas the solar nebula is a cloud of interstellar gas and dust that condensed to form the entire solar system, including the sun and planets.
What is the process of condensation in the solar nebula?
Composition of the Solar Nebula. As the protoplanetary disk cools, materials in the disk condensate into planetesimals. The solar nebular contains 98% Hydrogen and Helium (produced in the Big Bang), and 2% everything else (heavy elements, fusion products inside the stars).
How does the condensation sequence theory explain the similarities and differences between Jovian and terrestrial planets?
The condensation theory can explain the basic differences between the jovian and terrestrial planets because the temperature of the solar nebula would be expected to decrease with increasing distance from the Sun. … When the Sun became a star, its strong winds blew away any remaining gas in the solar nebula.What is the key ingredient in the modern condensation theory?
The key ingredient in the modern Condensation Theory is dust, which helps to cool the gas, and forms the nuclei for planetesimals to grow.
What happens gravitational condensation?
An object increases in size due to the addition of materials. What happens in the process of gravitational condensation? As the water is heated it changes forms from liquid to gas. Once you pull the lever, a plug gets opened automatically; this plug allows enough water to flow and fill up the basin.
What role did condensation temperatures play in the formation of the planets?
As the solar nebula began to rotate more rapidly, it also tended to flatten out, forming a planetary disk. … In the inner part of the solar system where the temperature was high, only substances with high-condensation temperatures could become planets.
What is an Exosolar system?
extrasolar planet, also called exoplanet, any planetary body that is outside the solar system and that usually orbits a star other than the Sun. Extrasolar planets were first discovered in 1992. More than 4,000 are known, and about 6,000 await further confirmation. HR 8799 system.What is the difference between condensation and accretion?
Condensation is the building of larger particles one atom (or molecule) at a time, whereas accretion is the sticking together of larger particles. … The planets swept up gas, dust, and small particles.
Why do you think the inner planets are small and dense while the outer planets are gas giants?The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. … The inner planets are much smaller than the outer planets and because of this have relatively low gravity and were not able to attract large amounts of gas to their atmospheres.
Article first time published onWhat is one major similarity between a Jovian planet and a terrestrial planet?
Similarities: They were all formed at roghly the same time 4.6 billion years ago. All of them/both Jovian and Terrestrial planets orbit the sun. Both groups have magnetic fields.
What do you think is the difference between the terrestrial and jovian planets?
The main atmosphere of terrestrial planets is a gaseous mix of carbon dioxide and nitrogen gases, and all terrestrial planets have rocky surfaces. … Jovian planets are larger, further from the sun, rotate faster, have more moons, have more rings, are less dense overall and have denser cores than terrestrial planets.
Why is dust important to the condensation sequence?
Why is dust important to the condensation sequence? (a) Without dust, water vapor in Earth’s atmosphere would never have fallen to the surface as liquid water.
Why are condensation nuclei needed for clouds to form?
The formation of clouds, fog, or haze requires the assistance of condensation nuclei. … Condensation nuclei provide the non-gaseous surface necessary for water vapor to condense into cloud droplets. As droplets join together they grow larger and eventually fall as precipitation.
Who discovered condensation theory?
solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart.
What is condensation accretion?
Condensation: It is the process of addition of the material to an object or material or molecule at a time. Accretion: It is the process of addition of the large particles such as collection of atoms and/or molecules etc. to an object.
Why do the Moon and Mercury have no significant atmospheres unlike Earth?
Why do the Moon and Mercury have no significant atmospheres, unlike Earth? Both have low escape speeds than Earth and their temperature caused their atmosphere to escape.
Why did the solar system flatten?
It’s thought to have arisen from an amorphous cloud of gas and dust in space. The original cloud was spinning, and this spin caused it to flatten out into a disk shape. The sun and planets are believed to have formed out of this disk, which is why, today, the planets still orbit in a single plane around our sun.
Is Uranus an inner or outer planet?
The Outer Planets These planets are much larger than the inner planets and are made primarily of gases and liquids, so they are also called gas giants. This image shows the four outer planets and the Sun, with sizes to scale. From left to right, the outer planets are Jupiter, Saturn, Uranus, and Neptune.
What is condensation temperature?
Condensation occurs when the water vapor in the air is cooled, changing from a gas to a liquid. This process can take place at various temperatures between 32 and 212 degrees Fahrenheit, or 0 and 100 degrees Celsius.
What is the most important factor for the formation of our planets?
A huge cloud of dust and gas collapsed and condensed. Gravity pulled matter into the center core, nuclear fusion began, and our Sun was created. Remaining matter and gas clumped together to form the planets.
In which order the events forming our solar system occur?
In which order did the events forming our solar system occur? The solar nebula became hot and dense pulling in more gas. … Most of the gas was pulled toward the center, where it became hot and dense, forming the Sun. The solar nebula spun faster and faster and flattened into a rotating disk.
Which terrestrial worlds have thin or no atmospheres?
Earth because it has cooled most slowly. Which Terrestrial worlds have thin or no atmosphere? Mercury and the Moon have no atmosphere.
How does the planetesimal theory of planet formation explain the asteroids?
The planetesimal theory is a theory on how planets form. According to the planetesimal hypothesis, when a planetary system is forming, there is a protoplanetary disk with materials from the nebulae from which the system came. … Other planetesimals turn into comets, Kuiper Belt Objects (KBOs), and trojan asteroids.
Why don t terrestrial planets have rings?
Why don’t terrestrial planets have rings like the Jovian planets? they do not have large enough masses to hold onto orbiting particles and they are too close to the sun, whose gravity would pull those particles away from them.
Why is exoplanet research important?
Observing exoplanets allows us to determine whether or not we actually understand those processes, even in our own solar system. … What finding exoplanets does for us is open up a vast exploration area to look for other habitable worlds. And it has upped the likelihood that we are not alone.”
What is exoplanet in Earth science?
An exoplanet is any planet beyond our solar system. Most orbit other stars, but free-floating exoplanets, called rogue planets, orbit the galactic center and are untethered to any star. Overview.
What are the properties of an exoplanet?
Unlike the nearly circular orbits of the planets in our solar system, most exoplanets exhibit largely eccentric orbits. Most of the known exoplanets are gaseous, similar to the giant planets in our solar system, although some of the smaller exoplanets found show signs of rockier, terrestrial compositions.
What is the difference in composition and density between the inner and outer planets?
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.
Why are the inner planets so small and rocky and outer planets so large and gassy quizlet?
What caused this difference? Inner planets are smaller than the outer planets; gas giants have more gravity; … Inner planets have most of their atmospheres burned away by sun.
Which order shows the size of the inner planets from smallest to largest?
It’s a real easy one too. To ensure that the list stays stuck, just think of something along the lines of “Mercury Met Venus Every Night Until Saturn Jumped.” Essentially, this indicates that the size of the planets in order from smallest to largest is Mercury, Mars, Venus, Earth, Neptune, Uranus, Saturn, and Jupiter.
