Scientists think the Earth's core contains iron because of the planet's magnetic field. Iron is a magnetic material, and the Earth's magnetic field is generated by the movement of molten iron in the outer core. Additionally, seismic waves and the density of the Earth indicate a high concentration of iron in the core.
Scientists think Earth's core is made of iron because iron is a dense material, and it is abundant in Earth's crust. Also, studies based on seismic waves and Earth's magnetic field support the idea that the core is composed mostly of iron.
Scientists think that plate motion is the result of the movement of material in the Earth's mantle. This movement is driven by processes such as mantle convection, where hot material rises and cool material sinks, generating forces that cause the tectonic plates to move.
Astronomers are considered earth scientists because they study celestial bodies such as stars, planets, and galaxies from a scientific perspective. Their work often involves understanding how these celestial bodies interact with Earth and the impact they have on our planet's environment and climate, making their research relevant to the study of Earth as a whole.
Scientists study Earth's interior to better understand the planet's composition, structure, and dynamics. This helps in predicting natural disasters like earthquakes and volcanic eruptions, as well as in understanding processes like plate tectonics and magnetic field generation. Studying the Earth's interior also provides insights into the planet's history and evolution.
4.6 billion years
Because he is..why do you think he isn't? becaus he is hot and nobody is hotter then him because hes sexi and is a great bassist and lyric writer and hotter then enybody on earth !
It would be hotter than it currently is.
iron
From the oceans
Most of them think Twilight sucks, if that's what you're getting at.
Everybody has a different opinion. Some people think that Deidara is hotter, and some people think that Itachi is hotter.
Many, many planetesmals and possibly a few protoplanets.
there was no oxygen in Earth's early atmosphere.
Because they're using a definition of "dinosaur" that allows them to think that.
The Outer Core. It Is Classified As A Liquid...Not A Solid (Like you think it would be;; That's what I got confused on) The evidence we have is that Scientists and those study people send waves down into earth and when the waves slow down they have hit liquid and when hit something solid they speed up and the deeper you go into the earth, the hotter it gets obviously. Hope this helps!
Most scientists say in about 13500. So I think that you have some time
