What do we mean by the frost line when we discuss the formation of planets in the solar nebula? It is a circle at a particular distance from the Sun, beyond which the temperature was low enough for ices to condense. What is the frost line in the solar nebula theory?
In astronomy or planetary science, the frost line, also known as the snow line or ice line, is the particular distance in the solar nebula from the central protostar where it is cold enough for volatile compounds such as water, ammonia, methane, carbon dioxide, and carbon monoxide to condense into solid ice grains.
What was the frost line in the solar nebula? Explain how temperature differences led to the formation of two distinct types of planets. The frost line in the solar nebula lies between Mars and Jupiter. It is the distance where it was cold enough for hydrogen compounds to condense into ices.
What do we mean by the frost line quizlet?
Frost line- the distance at which it was cold enough for ices to condense-, which lays between Mars and Jupiter today.
Those planets formed or that 'were' forming inside the inner dwellings of the Frost Line for example, Mars on wards to Mercury are made out of more rocky and metallic materials. This is because of the more exposure to the sun and less condensation of liquid water.
Astronomy - Ch. 8: Origin of the Solar System (10 of 19) The Frost Line
Summary: The terrestrial planets formed close to the Sun where temperatures were well suited for rock and metal to condense. The jovian planets formed outside what is called the frost line, where temperatures were low enough for ice condensation.
Why is the frost line important?
Frost line is the depth at which groundwater freezes.
The ground contains moisture that is used by plants and animals to live and thrive, however, when cold weather hits, the groundwater begins to freeze and expand, pushing and crushing objects that are in the frozen dirt.
Frost line is the area cold enough for hydrogen compounds to condense into ices. Frost line marked the transition between the warm inner regions of the solar system where terrestrial planets formed and the cool outer regions where Jovian planets formed.
When was the solar nebula created?
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula.
What is meant by the solar nebula quizlet?
solar nebula. a rotating cloud of gas and dust from which the sun and planets formed. nuclear fusion. the process by which nuclei of small atoms combine to form a new, more massive nucleus; the process releases energy.
The most widely accepted hypothesis of planetary formation is known as the nebular hypothesis. This hypothesis posits that, 4.6 billion years ago, the Solar System was formed by the gravitational collapse of a giant molecular cloud spanning several light-years.
What are four key features of our solar system that any theory of solar system formation must be able to explain? There are vast numbers of asteroids and comets. There are clear patterns to the rotation and orbits of large bodies in the solar system. There are a few notable "exceptions to the rules."
Where is the frost line of the solar system located from the Sun?
The frost line is a boundary between mostly ice-covered objects and mostly rock-covered objects. It is about 5 AU from the Sun.
What is a frost line in construction?
What Is the Frost Line? The frost line is the depth at which moisture will freeze in the ground. Due to variations in winter temperatures and soil moisture content, the frost line isn't the same everywhere.
What is the snow line in astronomy?
astronomers have dubbed the “snow line”—i.e., the minimum radius from the Sun at which water ice could have condensed, at about 150 K (−190 °F, −120 °C).
Planets form from particles in a disk of gas and dust, colliding and sticking together as they orbit the star. The planets nearest to the star tend to be rockier because the star's wind blows away their gases and because they are made of heavier materials attracted by the star's gravity.
Which of the following statements was true beyond the frost line but not interior to it )?
Which of the following statements was true beyond the frost line (but not interior to it)? It was cold enough for hydrogen compounds to condense into ices. Which of the following is thought to explain many of the "exceptions to the rules" of our solar system?
They either form through clouds of cold interstellar gas and dust or through the aftermath of a supernova. For example, in the Carina Nebula, hot, young stars erode and sculpt the clouds into this fantasy landscape by sending out thick stellar winds and scorching ultraviolet radiation.
We see stars forming in the depths of giant clouds of gas and dust, and we even see young stars with disks of debris around them, which look just like the debris disk we think the planets formed from. Other lines of evidence come from simulations of the process.
What two gases exist in abundance beyond the frost line of the solar system?
Which ingredients condensed inside and outside the frost line? Hydrogen and helium gas: these gases never condense in interstellar space. Hydrogen compounds: Materials such as water, methane, ammonia, can solidify into ices at low temperatures.
Which of the following types of material can condense into what we call ice at low temperatures?
Which of the following types of material can condense into what we call ice at low temperatures? –Hydrogen compounds such as water ammonia and methane are gaseous at high temperature but condense into ice at low temperature.
What do we mean by accretion in the context of planet formation?
In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes.
What does above the frost line mean?
Above the frost line, the ground can heave up, shifting whatever is in it, or freeze the pipes' contents. To avoid these issues, knowing the frost level in your area allows you to construct below the ground freezing depths to keep pipes flowing, decks level, and foundations stable.
What is frost line height?
The distance from the die is called the height of the frost line. It depends on various factors, including the melt temperature, the speed of cooling, the extrusion speed, and the diameter of the bubble.
What is the ground temperature below the frost line?
Throughout most of the U.S., the temperature of the ground below the frost line (about 3 to 5 feet below the surface) remains at a nearly constant temperature, generally in the 45 ° -50 ° F range in northern latitudes, and in the 50 ° -70 ° F range in the south.
