the layer in the earth I did it before
A treaty designed to protect the ozone layer via phasing out the production of multiple substances responsible for the ozone layer depleting.
Explanation:
The giant landmass described by Wegener in his continental drift hypothesis has broken down into different slabs and they have moved to new positions. The giant landmass is called Pangaea. Pangaea is a supercontinent believed to have produced the continents today.
- The break up of the supercontinent started about 175million years ago.
- Today, it is understood that the concept of plate tectonics provides an insight into how the supercontinent have broken down and migrated to their present position today.
- Plate tectonics also provides a mechanism that provided motion for the plate.
- Wegener from his observation suggested that the continent could easily fit into a single supercontinent like the pieces of a puzzle.
- He also suggested evidence from across the various continents to back up his claim.
