How would an ice core from a time when the Earth was heating up compare with a time when it was cooling down?
Answers
It is easy
Step-by-step explanation:
THE think first you want to know that is what is a ice Core then you will get the answer easily
is estimated that the earth's core is cooling at a rate of about 100 degrees Celsius per billion years.[1]
is estimated that the earth's core is cooling at a rate of about 100 degrees Celsius per billion years.[1]One billion years from now, the energy produced by the sun will have increased to a point in which all of the earth oceans will have burned away.
is estimated that the earth's core is cooling at a rate of about 100 degrees Celsius per billion years.[1]One billion years from now, the energy produced by the sun will have increased to a point in which all of the earth oceans will have burned away.Three billion years after that, the sun will grow to become a red giant and will envelop the earth.
So, if today's core temperature is approximately 5,400C, it will be approximately 5,000C when the earth is absorbed by our sun.It isn't set in stone that the earth will be consumed by the sun as there isn't general agreement on the suns ultimate diameter. Also, earth is moving 15 cm a year farther from the sun due to tidal locking with the sun, In 5 billion years Earth will be 50 million miles farther from the sun. In that scenario Earth;s core will remain liquid for 91 billion years before cooling enough to become solid.
