3) wildlife from disappearing.

Origin: The older hypothesis is that it lies in a true rift zone, an extension of the Red Sea Rift, or even of the Great Rift Valley of eastern Africa. A more recent hypothesis is that the Dead Sea basin is a consequence of a «step-over» discontinuity along the Dead Sea Transform.
Wildlife: Many animal species live in the mountains surrounding the Dead Sea: camels, ibex, hares, hyraxes, jackals, foxes, and even leopards. Hundreds of bird species inhabit the zone as well. The delta of the Jordan river was a jungle of papyrus and palm trees.

of shifting colored lights. The northern lights are called

Area: No specific or consistent measurements.

Aurora

The Natural Wonders of the World

The South and North Poles

Origin: Aurora displays are the result of electrical particles flowing out from the Sun. These particles pass through the Earth's magnetic field, and collide with atoms in the upper atmosphere causing them to emit electromagnetic radiation in the visible portion of the spectrum. The colors of the aurora depend on the altitude at which the atomic collisions occur and the type of atoms that are struck. If oxygen atoms are hit, the glow may be red or yellow-green; if the particles strike nitrogen atoms, blue or purple lights result.
