how can you say the earth is still very active?
Answers
Answer:The evidence point to a simple mechanism: The bulk of the Earth’s volume is still hot, molten rock because of radioactive decay.
A few centuries back, a common explanation was that it was leftover heat from all the collisions that formed the Earth around 4 billion years ago. As geologists improved their knowledge of the planet’s structure, it was eventually shown that, while that hot origin with radiative cooling had happened, it would have cooled the planet’s interior completely within only a few million years. So they had to look for a different explanation for the current high temperature, and over the 20th century, they verified that the decay of leftover radioactive isotopes in the original planet easily explained it.
Answer:
WTF!!!
Explanation:
UR ACTIVE IN BRAINLY BCOZ BRAINLY APP IS ACTIVE
BRAINLY APP IS ACTIVE BCOZ THE FOUNDERS ARE ACTIVE
THE FOUNDERS ARE ACTIVE BCOZ THEIR BRAINS ARE ACTIVE
AT THE END WE WILL UNDERSTAND THAT THE BRAINS MAKE EARTH ACTIVE FOR U THE EARTH IS NOT ACTIVE BCOZ U DONT HAVE THAT THING ON UR HEAD I GUESS :)
