The decay of radioactive elements creates heat, and the decay of certain radioactive elements can take billions of years. Additionally, the heat in Earth's interior is partially created by compressional forces and friction between the particles that make up the Earth. This heat is insulated, depending on depth, by thousands of miles of overlying material which makes it difficult for the heat to escape to the surface. As the radioactive isotopes gradually decrease in number, and the heat gradually escapes to space, Earth is gradually becoming cooler. Because these processes take billions of years, their effects go unnoticed due to small organism lifespans.
Our mother earth can be around for more than billion of years. She have been around for more than 4.5 billion years and she is still here.
Earth did not exist 700 billion years ago, nor did the universe. Earth is about 4.6 billion years old.
No, the earth wasn't around 7 billion years ago. Earth formed about 4.6 billion years ago.
No, earth will not disintegrate in 2 billion years. We have about 5 billion years before the sun expands.
== == The age of the Earth is roughly 4.6 billion years.

It is just a fact that earth is 4.6 billion years old.
The Earth is currently 4.5 billion years, so in approximately 2.5 billion years time.
No. The universe itself is about 13.7 billion years old. Earth is between 4.5 and 4.6 billion years old.
You can't find rocks 4.5 to 5 billion years ago because the earth was still so hot that it was still liquid and there were no rocks yet.
The Earth is about 4.5 billion years old. Life appeared on Earth about 3.5 billion years ago. The Earth would have been about 1 billion years old at that time.
No, rocks that are 3.5 billion years were not present when earth was first formed. Earth formed about 4.6 billion years ago.
yes the earth is still going to be around but the earth will never ever blow up.
