Geological Change and Time Activity

4. • The name of the major ocean during the
Paleozoic Era was the Panthalasic Ocean.

5. • The Appalachian Mountains were first noted on the
Early Devonian map which was approximately 400 million years ago.
• This is the period of the Paleozic when forests begin to form and fish began
migrating from the Southern hemisphere (Scotose, 2003)

6. • Small formations of the modern day map of Earth can be seen
on this Early Carboniferous map, such as, the Yucatan Peninsula
below what is known today as Mexico.
• According to the names of the periods, it seems that the Early
Carboniferous period is when coal began to form since coal’s
elemental form is carbon.
• As the area between Euramerica and Gondwana began to close, the
South Pole formed an ice cap which started changing the climate.

7. • Gondwana is the name of the large landmass that occupied the surface of
the earth until the late Permian period.
• At the end of the Paleozoic period, Pangea
joined all the landmasses together.
• The modern day continents, are much more
recognizable during the Late Permian period.

9.  Dinosaurs dominated the earth during
the Mesozoic period, fauna began
forming and it was a relatively warm
period of time on the earth.

10. • During the Jurassic period the Central Atlantic Ocean began to form as North America
moved to the Northwest.
• The Panthalassic and Tethys Oceans lead to the formation of the Atlantic, Indian, and
Pacific Oceans.
• According to the coloring of the Early Jurassic map, it looks as though the Rocky
Mountains were beginning to form. In the Jurassic map, it is obvious that there is a
mountain range in the area of the Rocky Mountains.

11. • During the Cretaceous period, the map shows India as separated from Africa and
Antarctica. India was then north of Antarctica and east of Africa and finally many
years later, ends up as part of Asia.

13. • During the Eocene period, the map shows the Himalayas forming
before India meets Asia

14. • On the map of the Miocene period, the land masses resemble today’s
modern map. India has collided with Asia by this period.

15. • During the Cenzoic Era and Beyond, the world was in a colder
climate than the Mesozoic but after the glacial period it began to
warm.

16. • By the end of the Future World period, the landmasses have once again come
together, not in a complete continent but very closely situated. The oceans are now
one large ocean and are not divided.
