| I would like to know if the layers of the earth
have changed over time? |
| Question Date: 2013-03-06 | | Answer 1:
Yes, the interior of the Earth is in constant
motion. The speed at which hot rock flows around
like a viscous fluid is about 1 inch per
year.
| | Answer 2:
Geologic forces on Earth are constantly
adding new layers of rock, as old rocks are
eroded away and new volcanoes erupt new
lavas.
