What do geologists think earth's core contains mostly iron?
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 deep inside the earth?
The layers of the Earth go in this order:Crust- Oceanic crust (basalt) and Continental crust (granite) Solid rockLithosphere Solid rockAsthenosphere Liquid rockLower mantle Solid rockOuter core Magma/thick liquid metalInner core Solid metal
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 do geologists think cause the earth's 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 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.
How old do geologists think the earth is?
Geologists and other related Earth scientists have estimated the age of the Earth to be approximately 4.65 Billion years old based on a wide variety of scientific experiments and data.
Why do geologists think that the temperature increases with depth?
because of the core (center of the Earth) emits immense heat.
Why do you think geologists study the processes involved in creating and changing formations?
To better understand our earth and how it has evolved.
What do geologists think creates earths magnetic field?
Electric currents in Earth's molten outer core.
How do geologists think earths atmosphere formed?
how do geologists think earths atmosphere is formed
Why do you think geologists study the process involved in creating and changing rock formation?
To better understand our earth and how it has evolved.
Why do geologists think that the core of the Earth is mostly iron?
The composition of the Earth's core (iron and nickel) is implied by the elemental composition of meteorites, which contain substantial iron. The gravitational field of Earth also suggests an average density that is consistent with a large iron content. Additionally, the Earth's magnetic field is assumed to depend on a large core of ferromagnetic elements.
Where is the most silica in the earth?
I think silica can be found mostly in the center of the earth ( the core).-s
Is earth approximately 4600 years old?
The earth is approximately 6000 years old according to the Bible. Most geologists think that the earth is about 4.3 billion years old. You are free to accept whatever approach suits you.
