The ocean covers more than seventy percent of Earth, and it drives one of the most important cycles in nature.
Water is always moving - from the sea into the sky and back down to the ground again.
When the sun heats the ocean surface, water evaporates and rises into the air as vapor .

High above the ground, this vapor cools and forms clouds that travel across continents .
When those clouds become heavy enough, they release rain or snow over land.
Rivers carry this fresh water from mountains and plains back toward the sea.
Along the way, rivers shape valleys, feed forests, and supply drinking water to millions of people.

Once water reaches the ocean, it does not simply stay still.
Deep currents move cold water from the poles toward the equator, regulating the climate around the world.
These same currents carry nutrients that support fish, whales, and countless other sea creatures.
The ocean also absorbs large amounts of carbon dioxide, which helps slow the effects of climate change.

However, pollution and rising temperatures are making it harder for the ocean to do these jobs.
Scientists warn that without cleaner practices, ocean ecosystems could collapse within this century.
The journey of water around Earth reminds us that every drop we waste or pollute has consequences far beyond our backyard.
