Best answer: What was the frost line of the solar system quizlet?

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 is the frost line of the solar system?

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 is 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.

Why are the inner planets made of denser materials than the outer planets quizlet?

Why are the inner planets made of denser materials than the outer planets? In the inner part of the nebula only metals and rocks were able to condense because of the high temperatures, whereas hydrogen compounds, although more abundant, were only able to condense in the cooler outer regions.

Why are the inner terrestrial planets made of denser materials than the outer Jovian planets?

Why are the inner planets made of denser materials than the outer planets? A) The Sun’s gravity pulled denser materials toward the inner part of the solar nebula, while lighter gases escaped more easily.

Why is the frost line important?

The frost line is the deepest depth at which the moisture present in the soil is expected to freeze. Once the bottom of your footings is buried below the frost line, the residual heat in the ground below the footing will ensure the soil below the footing will not freeze in the winter.

How was the frost line formed?

In the close region, volatiles such as water and ammonia are broken apart or pushed outward by solar wind. As a result, material in an inner solar system will tend to be more dry and rocky, while the colder outer region will be more wet and icy. Dividing these two regions is a frost line or ice line.

What was the frost line which ingredients condensed inside and outside the frost line what role did it play in the formation of two distinct types of planets?

What was the frost line? Which ingredients condensed inside and outside the frost line? What role did it play in the formation of two distinct types of planets. Frost line is the area cold enough for hydrogen compounds to condense into ices.

How did the planets end up in our solar system quizlet?

Terms in this set (10)

How did the planets end up in our Solar System? After the Solar Nebula collapsed into a disk, dense regions came together to form planetesimals, which accreted other planetesimals until they became planets.

What do we mean by the frost line when we discuss the formation of planets in the solar nebula?

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 ‘giant impact hypothesis’ for the origin of the Moon?

What two gases exist in abundance beyond the frost line of the solar system?

Hydrogen and helium do not condense in the solar nebula, and are rather abundant in the large orbits of objects in the outer solar system. As the outer planetesimals continued to grow larger, the strength of their gravity grew stronger.

Why do we think mercury has so many tremendous cliffs?

14)Why do we think Mercury has so many tremendous cliffs? They were probably formed by tectonic stresses when the entire planet shrank as its core cooled.

Which planet other than Earth has visible water ice on it quizlet?

Mercury. Which planet, other than Earth, has visible water ice on it? Pluto is different from the outer planets in all of the following ways except which one? Its surface temperature is very cold.

Why is Pluto not a planet?

Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

How did the moon get in the sky?

What is most widely accepted today is the giant-impact theory. It proposes that the Moon formed during a collision between the Earth and another small planet, about the size of Mars. The debris from this impact collected in an orbit around Earth to form the Moon.

Which planet other than Earth has visible water ice on it?

Earth is the only known planet to have bodies of liquid water on its surface. Europa is thought to have subsurface liquid water. Scientists hypothesize that Europa’s hidden ocean is salty, tidal, and causes its ice surface to move, resulting in large fractures which are clearly visible in the above image.
