With out cainozoic tectonic movements,E. Africa would have had a poor resource base" Elucidate?

Question

could you please explain what those cainozoic tectonic movements are, what caused them, and more answers to the ones i recieved yesturday
thank yuo very much

Answer 1

From Wikipedia:

The Cenozoic Era; is the most recent of the three classic geological eras. It covers the 65.5 million years since the Cretaceous-Tertiary extinction event at the end of the Cretaceous that marked the demise of the last non-feathered dinosaurs and the end of the Mesozoic Era. The Cenozoic era is ongoing.

The Cenozoic is divided into two periods, the Palaeogene and Neogene, and they are in turn divided into epochs. The Palaeogene consists of the Paleocene, Eocene, and Oligocene epochs, and the Neogene consists of the Miocene, Pliocene, Pleistocene, and Holocene epochs, the last of which is ongoing. Historically, the Cenozoic has been divided into periods (or sub-eras) named the Tertiary (Paleocene to Pliocene) and Quaternary (Pleistocene and Holocene), although most geologists no longer recognize them.

Life in the Cenozoic Era
The Cenozoic is the age of new life. During the Cenozoic, mammals diverged from a few small, simple, generalized forms into a diverse collection of terrestrial, marine, and flying animals. The Cenozoic is just as much the age of savannas, or the age of co-dependent flowering plants and insects. Birds also evolved substantially in the Cenozoic.

Geologically, the Cenozoic is the era when continents moved into their current positions. Australia-New Guinea split from Gondwana to drift north and, eventually, abut South-east Asia; Antarctica moved into its current position over the South Pole; the Atlantic Ocean widened and, later in the era, South America became attached to North America.

From Teacher Man:

Thus, the answer is that because of tectonic plate activity from this period, the fossil remains decayed and produced the "resource base" E Africa enjoys today--oil, diamonds, mining, etc...

Good Luck....
