What are the three common substances that are believed to be important in planet formation?
The three common substances believed to have been important in planet formation are (d) rocks, ices, and gas.
What name is given to the concentration of mass that formed at the center of the solar nebula eventually becoming the Sun?
protosun
Collisions between particles converted this energy into heat (random motions). The solar nebula became hottest near the center where much of the mass was collected to form the protosun(the cloud of gas that became Sun).
What object in the solar system is the most likely to harbor life that would change our view of how life works?
What object in the Solar System is the most likely to harbor life that would change our view of how life works? c. The Sun. Observers in a distant solar system are watching our Sun and using the radial velocity method to try to determine whether the Sun has planets.
Which of these time sequences for the formation of the solar system is most probable?
The most probable time sequence for the formation of the solar system was the following: The Sun contracted first as a gas ball, and the planets and moons formed shortly afterward by accretion and condensation.
How many years ago did the solar system begin to form?
4.6 billion years ago
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula.
How old is the solar system?
4.571 billion years
Solar System/Age
Formation. Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust.
How did planets form in the early solar system?
Uranus and Neptune are thought to have formed after Jupiter and Saturn did, when the strong solar wind had blown away much of the disc material. As a result, those planets accumulated little hydrogen and helium—not more than 1 M Earth each. Uranus and Neptune are sometimes referred to as failed cores.
How do astronomers know that the age of the solar system is about 4.5 billion years old?
By studying several things, mostly meteorites, and using radioactive dating techniques, specifically looking at daughter isotopes, scientists have determined that the Solar System is 4.6 billion years old.
Which of these time sequences for the formation of the solar system is most probable quizlet?
How much old is solar system?
Age and Origin of the Solar System. The age of the solar system, derived from the study of meteorites (thought to be the oldest accessible material around) is near 5 billion years; that of the Earth is taken as 4.6 billion years.
