Exploring Africa's Physical and Cultural Geography Using GIS
Activity 4 - Answer Key
Question 1
[The majority of the earthquakes in the world are located at, or near
the plate boundaries. Plates are always moving and build up pressure.
Convergent boundaries exist where plates collide creating mountain
chains and volcanoes. Divergent boundaries exist where plates spread
apart. Transform boundaries exist where plates slide past each other.]
Question 2
[Most of Africa's earthquakes occur in the middle of the African continent,
or plate, far from any plate boundaries.]
Question 3
[The African Rift Zone is located in the countries of Ethiopia and Kenya.]
Question 4
[Earthquakes affect people along the Western boundaries of North and
South America because the plate boundaries are along the western
boundary of those continents. Plate boundaries are far from the
continent of Africa; the earthquake potential is minimal.]
Question 5
[Largest recorded earthquake in the world was 9.3 in Indonesia in
the year of 1996.]
Question 6
[The majority of the world's volcanoes are located around the
"Ring of Fire" around the Pacific Ocean. The oceanic plates are all
diving (converging) with other plates causing the diving plates to
melt and push molten rock to the surface, erupting as volcanoes.]
Question 7
[Mt. Kilimanjaro is the highest in Africa at 5895 meters, located near
the border between Kenya and Tanzania.]
