The scientist use trees and rocks to prove it. You can find stuff like coins from long ago to see how old are stuff on earth.]]> 2020-05-05 16:55:37 UTC https://padlet.com/ccastellon2/dodmooe0x14vq6sj/wish/552693890 sofia 12370192 https://padlet.com/ccastellon2/dodmooe0x14vq6sj/wish/552972566 i learned that there is many ways of telling hoe old the earth is like using tress like how jeremy said and using rocks]]> 2020-05-05 18:43:27 UTC https://padlet.com/ccastellon2/dodmooe0x14vq6sj/wish/552972566 Aaron https://padlet.com/ccastellon2/dodmooe0x14vq6sj/wish/552992491 2020-05-05 18:51:13 UTC https://padlet.com/ccastellon2/dodmooe0x14vq6sj/wish/552992491 https://padlet.com/ccastellon2/dodmooe0x14vq6sj/wish/553066681 I learned that you can count how many rings are in a tree to see how many years the trees have been alive.
