Current Events
By Crash Course Kids (Science) [5:06] Description: What are air currents? Air currents are like rivers of wind caused by areas of high and low pressure. The air above the land is warmer and less dense, so it rises. The air over the water is cooler and heavier. The cool air rushes in toward the low-pressure zone over the land, forming a lovely sea breeze. But what about Jet Streams? In this episode of Crash Course Kids, Sabrina chats with us about all things relating to Air Currents. |

Where Does Wind Come From?
By Crash Course (Geography) [11:18] Description: There's an invisible force shaping our lives, affecting the weather, climate, land, economy, and just whether a flag looks majestic or not - we're talking about the wind! Today we’re going to go into the science of where the wind comes from and take a closer look at the major wind systems and pressure belts across the globe. We'll explain how the Coriolis effect causes the winds to curve (and makes air travel a bit more complicated), explore the doldrums and horse latitudes that could stall ships for days, and show the enormous impact the trade winds had on European colonization of the Americas. |

Global Circulation Part 1: Differential Heating
By the Met Office [2:50] Description: The climate we experience and the location of the world’s deserts and rainforests are controlled by how air moves around the globe, a process known as Global Circulation. |
|
Global Circulation Part 2: The Three Cells
By the Met Office [3:35] Description: Global circulation on our rotating Earth splits the atmosphere into three cells in each hemisphere: the Hadley cell, Ferrel cell and Polar cell. In this video, we look at how air moves around each cell and how this controls the location of the world’s deserts and rainforests. |

Global Circulation Part 3: The Coriolis Effect and Winds
By the Met Office [6:18] Description: In this third, and final, video in the Global Circulation series we look at how the rotation of the Earth influences our winds through the Coriolis effect and gives us jet streams and prevailing wind patterns. |

Ocean Currents
How Do Ocean Currents Work
By TED Ed [4:33] Description: Dive into the science of ocean currents (including the Global Conveyor Belt current), and find out how climate change affects them. |

How Do Oceans Circulate?
By Crash Course (Geography) [11:02] Description: Today, we're going to take a closer look at how the oceans circulate by following the life of a discarded water bottle as it gets snagged in the North Pacific Garbage Patch. We'll talk about what causes the movement of water, called current, both near the surface and much deeper in the oceans, and we'll show how they follow similar (but not identical) paths to the winds. Ocean circulation plays a huge role in cycling vital nutrients within the seas and helps us transport goods on ships across the globe and it's up to us to protect it. |
