Why do scientists think earth's core contains iron?

Hello There!

Scientists think that the earths core contains iron because they have inferred that the core is iron by conducting seismic experiments. The magnetic field is also a strong clue.

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )
