What do meteorites reveal about the solar system?

What do meteorites reveal about the solar system? They reveal that the age of the solar system is approximately 4.6 billion years. (Note that while it is true that the early solar system consisted mainly of hydrogen and helium gas, meteorites do not tell us this because they are made of rock and metal.)

What happened during the accretion phase of the early solar system quizlet?

What happened during the accretion phase of the early solar system? Particles grew by colliding and sticking together. … They were formed by condensation and accretion in a disk of gas around the planet. Observations of young stars (as well as theory) tell us that when the Sun was young the solar wind ?

What law explains why the center of the cloud becomes so much hotter as the cloud shrinks in size?

It got hotter, its rate of rotation increased, and it flattened into a disk. … What physical law explains why a cloud will rotate rapidly as it collapses? the law of conservation of angular momentum. The nebular theory also predicts that the cloud should heat up as it collapses.

What can we learn from meteorites?

Meteorites from asteroids and even from other planets help scientists understand all planets in our solar system, particularly the processes taking place deep inside. Although no one has ever been to the center of Earth, we know from meteorites that Earth has a center, or core, made of nickel and iron metal.

How do I know if I have a meteorite?

Practically all meteorites contain a significant amount of extraterrestrial iron and nickel, so the first step in identifying a possible meteorite is the magnet test. Iron and stony-iron meteorites are rich in iron, and will stick to a powerful magnet so strongly that it can be difficult to separate them!

How many asteroids hit Earth per year?

500 meteorites

How long did the heavy bombardment phase of the solar system last quizlet?

The heavy bombardment phase of the solar system lasted how long? Several hundreds of millions of years. Suppose you find a rock that contains some potassium -40 (half -life of 1.3 billion years).

Why did the solar nebula heat up as it collapsed quizlet?

Why did the solar nebula heat up as it collapsed? As the cloud shrank, its gravitational potential energy was converted to kinetic energy and then into thermal shock. … It flattened as a natural consequence of collisions between particles in the nebula, changing random motions into more orderly ones.

What was 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.
