They believe that Earth was once all molten when it was first forming. Since iron is one of the heavier elements, it would have sank to the inside of the earth due to gravity.

Most geologists think that the movement of earths plates caused by?
Geologists have hypothesized that the movement of tectonic plates is related to convection currents in the earth's mantle. Convection currents describe the rising, spread, and sinking of gas, liquid, or molten material caused by the application of heat.
Why do geologists think that seamounts are extinct volcanoes?
beacuse the seamounts were once formed as volcanoes
What is bigger earths moon or Mars?
I think Mars is bigger than Earths moon.
What is dourman volcano?
i think you mean "doormant". A dormant volcano is one that isn't currently active or erupting, but geologists think that it's still capable of erupting.
What are most of earths dormant volcanoes located?
I think the ring of fire
How do geologists think earths atmosphere formed?
how do geologists think earths atmosphere is formed
What element makes up of the earths core?
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
What element makes up most of the earths core?
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
What do geologists think creates earths magnetic field?
Electric currents in Earth's molten outer core.
Why do you think geologists use drills bits covered with small diamonds to drill earths crusts?
Because they have to get through the minerals and rocks in the earths crust.
What do geologists think causes earths plates to move?
The movement of the Earth's plates is known as plate tectonics. Geologists think the plates move due to a build up of extreme heat in the Earth's crust.
What part of the earths system contains the air you breath?
I think it's the atmosphere
Why do scientist think earths core contains iron?
other orbiting bodies contain more iron than earths crust does

Why do scientists think the earths core contains iron?
Iron is magnetic which forms the Earth's magnetic field.
Why do you think that the work of geologists is important to our daily lives?
geologists affect our lives in the following ways. they monitor seismic activities within the earths interior and are able to warn us of impending earthquakes and impending shockwaves geologists monitor volcanoes and are able tom predict when the next eruption will occur and the expected magnitude geologists are also important in the process of drilling boreholes as they have crucial information on the type of soil found in different areas and they can offer crucial advice in the process of drilling bore holes geologists also moniter the earths magnetic fields and can use this fields to date rocks which can then tell us crucial movements of tectonic plates
What do you think earths atmosphere would be like today if life had not evolved on earth?
Almost no oxygen, lots of CO2, still mostly nitrogen.
