What is the heat source?
The earth has not finished cooling down from when it was covered in lava. Once it is done cooling, the earth will be like a giant and permanent ice age radioactivity it says so
Where is does energy coming from if the Conservation of energy tells us that energy cannot be created or destroyed Clearly energy is required for radioactivity to occur?
Energy coming to the earth and radioactivity are not same. Energy comes mostly from the sun and other parts of space. The energy of radioactivity is already bound up inside of the atom.
What are examples of radioactivity?
For example natural and artificial radioactivity.
What are radioactivity?
Radioactivity was discovered by Henry Becquerel but the term 'Radioactivity' was given by Madam Curie. It is the process of process of spontaneous disintegration of nucleus and is measured by Geiger counter.
Where does most of the radioactivity that you personally encounter come from?
The radioactivity that people encounter on a regular basis actually comes from their natural environment rather than the radioactivity being from some manmade source.
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.
How is radioactivity of elements used to determine the age of the earth?
It finds the half-life of rocks.
Is radioactivity on the earth something relativity new?
no. radioactivity has been around since the earth's beginnings.
What is the heat source?
The earth has not finished cooling down from when it was covered in lava. Once it is done cooling, the earth will be like a giant and permanent ice age radioactivity it says so
What is the mantles heat source?
The earth has not finished cooling down from when it was covered in lava. Once it is done cooling, the earth will be like a giant and permanent ice age radioactivity it says so
How does magma get so hot?
Radioactivity within the Earth.
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).
What causes the temperature to change the crust of earth to the core?
Pressure and radioactivity.
What does the earths internal thermal energy come from?
From radioactivity in the Earth's interior.
What led scientist to infer that the earth is 4.6 billion years old?
Radioactivity
Scientists use radioactivity in rock samples to measure?
The exact age of the rock.
