We deduce that the Earth's core is mostly iron from observations of the commonality of iron which occurs in meteorites, from studies of the magnetosphere, from the effects of Earth's gravity on objects in space and the inference that the core must be of greater density than the crust and mantle to have the effect it does, and on the speed at which seismic waves travel through the various layers of the Earth.
What else can I help you with?
What do geologist look at for proof earths core contains mostly iron?
Comits
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.
Why do scientist think earths core contains iron?
Scientists believe Earth's core contains iron because of the planet's density and magnetic field. Iron is a dense material that would sink towards the core during the Earth's formation. The presence of iron is also supported by seismic wave behavior and the Earth's magnetic field, which is generated by the movement of molten iron in the outer core.
Is there a bunny in the earths core?
no it is not true. there is solid iron and nickel in the Earths core
Why do scientists think the earths core contains iron?
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.
The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
Why do scientists thinks earths core contains iron?
The iron nickel core has been determined to actually exist from the examination of meteorites, from the gravitational field of Earth, and from the Earth's density in comparison to its volume.
What element makes up most of the earths core?
Iron is the primary element that makes up most of the Earth's core. It accounts for about 85% of the core's composition, with the rest likely being nickel in combination with some lighter elements.
What is in the earths inner core?
a solid ball of iron
What are the main metals in the earths core?
nickel and iron
Why do scientists think Earths core contains iron?
Scientists believe Earth's core contains iron because it is consistent with the planet's overall composition and density. Iron is one of the most abundant elements in the Earth's crust and mantle, so it is likely to be present in the core as well. Additionally, the magnetic properties of the Earth can be explained by the presence of iron in the core.
WHY do scientists think earths core contains irons?
The iron nickel core has been determined to actually exist from the examination of meteorites, from the gravitational field of Earth, and from the Earth's density in comparison to its volume.
