How do astronomers determine the origin of a meteorite
that reaches Earth?
Choose one or more:
A.by its pre-collision orbit
B.by its size
C.by where it is discovered on Earth
D.by its chemical makeup
E.by its structure
Homework Answers
Ans.
Astronomers focus on the following things while identifying a meteorites' origin -
1. Chemical make up of the meteorite
2. dating is done then
Hence the correct option is (D)
If a meteorite has basalt rocks, we can say this came from a region where volcanism is common. If we find a meteorite fresh, it will be black in color and on the other hand, if it turns brown, it means it has gone through weathering and erosion on the earth and thus upper black layer has been removed.
I hope the answer is clear to you, in case you have any query, please leave a comment, we will try our best to fix it. If you are satisfied with the answer, leave a thumbs up, your support is valuable. Thank You

choose correct answer. no explanation needed
QUESTION 10 How do astrophysicists account for neutrino emission from the Sun? Solar flares create neutrinos with very energetic magnetic fields. Convection releases neutrinos, which random walk through the radiation zone. Fission in the Sun's core creates neutrinos when protons turn into neutrons. The annihilation of positrons and electrons in the core produces neutrinos. Fusion in the Sun's core creates neutrinos when protons turn into neutrons, QUESTION 11 How does the interstellar medium impact...

4. Matlab Solvers: A Case Study in Mechanics Suppose we have two objects orbiting in space, with masses 1 - and , rotating around each other. For example, think of the earth and the moon, where the moon moves around the earth at distance 1. (Of course, here both the masses and the distance are normalized.) A third object, which is relatively much smaller and does not affect the motion of the first two, is also orbiting in space. Think...

WHAT YOU CAN DO ABOUT CLIMATE CHANGE
The EPA has produced a guide about what individuals can do to help
reduce their contributions to climate change. Changes in the home,
yard, and on the road can reduce greenhouse gases and save money.
