Match the following

• (Rock) Land Evidence

• Similar ancient plant and animal fossils can be found on different continents all over the world indicating that those spots were once connected.

• Puzzle Evidence

• (shape of landmasses)   the edges of the continents fit together

• Fossil Evidence

• Rocks and mountain ranges on the margins of different continents have similar chemical properties, formed at the same time and formed under the same conditions

• Climate Evidence

• Glacial deposits, and fossils of plants and animals indicate that the continents were not always located where they are now.
