The Earth Unlocked Season 2: Episode Guide & Ratings

Extreme weather isn't exclusive to the planet; storms twice the size of Earth, winds faster than the strongest hurricanes, and towering tornadoes thousands of miles high all rage in the distant corners of the universe.

Pressure is the invisible force that drives weather; pressing down on Earth, it is the difference between a gentle breeze and a monster storm; learning how and why air can turn deadly.

Massive cuts into Earth's landscape create some of the most compelling and majestic formations; exploring how weather and geology combine to form vast canyons, from Arizona's arid Grand Canyon to the ocean's deepest depths.

From black sand bays to powdery white waterfronts, what wonders create these diverse landscapes and what dangers lurk, potentially turning these dream locations into seaside nightmares.

They are Earth's most visible formations, but secrets lie unseen beneath these massive mountains waiting to be unlocked.

The crust of the Earth is constantly moving, from shifting tectonic plates to the instability of the soil…the result? Catastrophic earthquakes, devastating dust bowls and weather induced landslides.

Islands are water-bound treasures of the planet; some are born from violent volcanic eruptions, while others give birth to scientific discovery; in a time of climate change, many islands face an uncertain future.

The pervasive but often overlooked force that shapes the environment; from scorching deserts to freezing polar regions, heat is the driving factor behind the Earth's diverse climates, influencing everything from weather patterns to ecosystems.
