Earth looked very different back then! The land was just bare grey rock, dust, and crashing waves.
The big idea
Long ago, tiny plants crept out of the ocean and changed bare Earth forever.
Fun facts
- β¨ The first land plants were tiny, soft mosses that didn't have any flowers or seeds!
- β¨ Early plants helped crumble tough rocks to make the very first soft dirt.
- β¨ So much fresh air was made by new plants that insects later grew as big as eagles!
Science words
