What is the main source of heat in Earth's interior?
the mantle plume There are two source of heat in the earth's interior. The main two sources are fire and breathing heat.
Explain why its impossible to ever really know the materials compose earth's interior?
Scientists have determined what the interior of the earth is like through analyzing seismic or earthquake wave
What is the main thing scientist observe in order to learn about the makeup of the earth's interior?
Scientists use seismic waves to study Earth's interior. Seismic waves travel through the Earth and can be detected far from their source.
What can be used to map the deep interior of the earth?
The deep interior of the Earth can be mapped using seismic waves. Natural earthquakes produce seismic signals which penetrate the Earth. Timing the arrival of these waves at various sites round the world, gives indication of the shape and the wave velocity in the Earths interior. Rather similar to the way a CAT scan can reveal the interior of a person.
How do geologists study Earth's interior directly?
They drill holes into the earth and collect rock samples.
What does the earths internal thermal energy come from?
From radioactivity in the Earth's interior.
Is radioactivity on the earth something relativity new?
no. radioactivity has been around since the earth's beginnings.
What has heat flow got to do with radioactivity?
The primal heat from the deep interior of the Earth is mainly due to radioactive decay, with a small contribution due to gravity compression.
How does mining help us to understand the interior of the earth?
Mining helps us to understand the interiors of the earth because we can learn about how long the earth has been around and about different kinds of dirt.
Of what importance is the study of earths interior to man?
The study of the earth's interior is important for man to understand his environment. It also helps to predict events that may occur on the earth's surface.
Is it possible to travel to the middle of the Earth's core?
No. Earth's interior is so hot that you could not even make it through the crust.
How does magma get so hot?
Radioactivity within the Earth.
What is the earth's interior?
The earth's interior is called the core.
Is there any way we can get to the Earth's inner core?
There's a slight chance one day we can, but that won't happen until our technology advances and we understand Earth's interior more.
How does radioactivity formation tell Earth's geologic story?
It Does a man
Is the Earth heated from the top or from the bottom?
Both. (the sun & radioactivity).
How did radioactivity change or impact the scientific world?
One thing is that now the correct age of the earth could be calculated. Before radioactivity was discovered the earth was though to have cooled enough to be only about 25 million years old by calculation. The discovery of radioactivity changed all that by increasing the heat the earth could radiate and so increasing the age of the earth dramatically.
