What statement accurately describes planetesimals?
A solar nebula collapsed. Which statement accurately describes planetesimals? They are the origins of planets. They formed from ice and rocks.
How are planetesimals formed?
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 . This material is gradually pulled together by gravity to form small chunks. These chunks get larger and larger until they form planetesimals.
Which statement accurately describes the universe quizlet?
Which statement accurately describes the universe? The universe consists of all the energy made by the Sun and stars. The universe consists of all physical objects on Earth and in space.

Masses of matter collide, masses of matter form around dust grain, and atoms and molecules are added to dust grain.
Which statement accurately describes dark matter?
Answer: Dark Matter is just matter that doesn’t interact via the Electromagnetic (EM) or Strong Nuclear forces . No EM interactions means that it can’t give off light, or absorb light, or reflect, refract, or scatter light in any way.
What statement accurately describes the universe?

What is a Jovian planet?
Also called “giant planets,” the Jovian planets occupy orbits in the outer solar system at distances ranging from 5 (Jupiter) to 30 (Neptune) times the Earth’s distance from the Sun . ...

Which statement accurately describes the outer planets quizlet?
Patterns of background radiation. Which statement accurately describes the outer planets? The outer planets have a high gravity due to their large size.
What is the correct order of steps in the formation sequence of a terrestrial planet?
Scientists believe that terrestrial planets, like Earth, formed by clumping together from dust and gas into into hot blobs of molten metal and rock several billion years ago. After becoming distinct planets, they went through four stages of formation: Differentiation, Cratering, Flooding and Surface Evolution .
Which planet form near the sun were the solar system temperatures were very high?
Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C).
How long ago did our solar system start to form?
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.
