Answer to Question 1

Answers should mention rivers, plains, mountains, forests, steppes.

Answer to Question 2

The magnetic polarity is the geographic orientation of the North and South Poles. Magnetic stripes develop as new crust is added to the ocean floor at mid-ocean ridges and cools, becoming magnetized according to the magnetic field that exists at the time. As this material moves away from the axis, new sea floor is created, and its magnetization may be reversed if Earth's magnetization has reversed polarity in the intervening time.
