The study of meteorites has helped us understand the beginnings of our solar system, how planets and asteroids formed and how impacts of large meteorites have altered Earth’s history and life on our planet.

How does the study of meteorites provide information about Earth’s core quizlet?
Meteorites are important to establishing the age of Earth because they were formed around the same time as Earth and thus iron meteorites are similar in composition to Earth’s core. The average composition of all meteorites reflects the average composition of Earth.

How are meteorites used to date the Earth?
Rocks, including meteorites, can be dated by looking at the ratios of certain radioactive isotopes (a method analogous to ‘radiocarbon dating’). Most meteorites turn out to be about 4.56 billion years old, because they come from asteroids that date from the creation of the Solar System.

Can meteorites help us understand what the inside of Earth is made of?
Meteorites come from space. The composition of all meteorites in the solar system tells us what the Earth is made of, so we can guess that elements that are common in meteorites but not on Earth’s surface are more common inward (e.g. iron), but we can tell more by the seismic waves traveling through the Earth.

Why are meteorites important to the study of Earth’s interior quizlet?
Why are meteorites considered important clues to the composition of Earth’s interior? Meteorites are thought to be made of the same material from which Earth was formed. Therefore, when they are found, they can give us an indication of the composition of the interior of Earth.

What provides us with the most information about the interior of the earth?
So scientists rely on seismic waves—shock waves generated by earthquakes and explosions that travel through Earth and across its surface—to reveal the structure of the interior of the planet.

What evidence indicates that Earth’s outer core is liquid quizlet?
The evidence which indicates that Earth’s outer core is liquid lies in the fact that S waves do not pass through the outer core. In addition to that, the outer core bends P waves.

What is the composition of the Earth’s core quizlet?
The core is thought to be metallic, composed mostly of iron and nickel. It has has an inner core (solid) and a molten outer core.

How are meteorites used to determine the age of Earth?
The ages of Earth and Moon rocks and of meteorites are measured by the decay of long-lived radioactive isotopes of elements that occur naturally in rocks and minerals and that decay with half lives of 700 million to more than 100 billion years to stable isotopes of other elements.

How can meteor impacts be used to date the age of Earth?
Short answer: because the meteorites formed together with the Earth and the rest of the Solar System. Long answer: The Earth formed together with the rest of the Solar System and its meteorites around 4.5 billion years ago.

How can meteorites tell us about the Earth?
The most important clues about the early stages of the solar system come from meteorites. Some are older than the formation of the Earth. They reveal how smaller bodies coalesced to form planets, and how our own planet developed after it had formed.

How does the study of meteorites help in understanding the internal composition of the Earth?
Now, by studying the composition of these meteorite fragments, researchers have unraveled the composition expected to be present in the Earth’s lower mantle which is at about 660 km deep. Studying the meteorite could also tell us more about how our Earth evolved from being a magma ocean to a rocky planet.
