Rain
E1
RainScientists are just now unlocking the amazing secrets of how rain is made; some raindrops form around micrometeorites from outer space, others are created by bacteria that float into the upper atmosphere.
Tsunamis
E2
TsunamisTsunamis form in the open ocean before making toward land. Science seeks not only to understand these giant waves but also predict them.
Gravity
E3
GravityEarthquakes can actually affect Earth's gravity, and the ability of scientists to map gravitational fiels has uncovered mysterious anomalies.
Goldilocks
E4
GoldilocksEarth's distance from the sun is just right to sustain life, with neighbors Venus and Mars illustrating the impact of a slight difference in location.
Magnetic Shield
E5
Magnetic ShieldA metallic core at the center of the Earth turns the planet into a magnet, generating a field that protects life on the surface from cosmic radiation.
Blizzards
E6
BlizzardsA visit to the researchers at a Colorado storm lab and an examination of lake-effect snow in northern New York reveal the science of blizzards.
Tides
E7
TidesExplore what drives the strange science behind places like Canada's Bay of Fundy-where water levels rise as much as 50 feet during high tide, and Alaska's Turnagain Arm, where 10-foot tall "bore waves" routinely wash in from the sea.
Volcanoes
E8
VolcanoesAs evidenced by the 1815 eruption of Indonesia Mt. Tambora, volcanoes can profoundly impact the weather, producing lightning, ash and acid rain.
Strangest Places
