  1. Social Studies Essential UNIT Question: How did geography affect the development of the Eastern hemisphere?

  2. Focus Question: • How did the geography of eastern Africa affect the development of human life?

  3. Geography in Motion: • Plate tectonics is the shifting of the Earth’s crust; • The Earth’s landforms once made up a single land mass called Pangea. • Through divergent and convergent movement, the Earth shifted over millions of years to form the present-day continents.

  4. The Earth in 50 Million Years Plate Tectonics are on-going and continue to shift the ground beneath our feet.

  5. The Effects of Plate Tectonics: • The Earth cooled and climates changed. • As a result, continents like Africa lost many of its forests. • Fossil records show that an ape-like ancestor of man emerged from the de-forested areas of east Africa to walk on two legs. (4 million years ago.)

The Pre-History of the Human Race • Humans evolved (to change over long periods of time) to avoid extinction. • Humans developed bipedalism: To walk on two feet. • Humans developed stereoscopic sight: To see across great distances, which alerted them to predators. • Humans developedopposable thumbs to buildtools out of stone and other materials. • Using tools made man more independent.
