Life in the sea around Australia seems to be rich. Yet in terms of marine biomass Australia is poor. For example some fifty other countries catch more fish than we do. Why are Australian waters less productive? In this programnm, we look at why some parts of the world’s seas are richer than others. We look at the marine carbon, nitrogen and phosphorus cycles, the biological carbon pump, how nutrients are distributed with depth and where and why upwellings occur. We also take a brief look at how humans are affecting the supply of nutrients with fertiliser run-off. Show Less
Learn all about the water cycle. What do the terms "evaporation," "condensation," and "precipitation" mean? Where is most of the earth’s water found? What is a glacier? How can we conserve water? The answers to all of these questions and more are covered in depth with detailed graphics, diagrams and exciting video. On-screen, multiple-choice reviews at the end of each segment reinforce important concepts and make learning fun. Show Less

In this video, we learn about forests, one of the world’s biggest biomes. We’ll start by discussing what a forest really is - because it’s a lot more than just trees! The forest is in many ways a key resource, above all for the climate, but also for the economy. The forest absorbs part of the carbon dioxide we release when we burn fossil fuels. We learn about the layers that make up a forest. We also take a closer look at the types of forest that exist and what plants and animals we find there. Why do leaves change color in the fall? We’ll learn that too. Show Less
This clip explains how the continents and oceans were formed as the Earth cooled after forming, and how continents moved into their current positions.
Ele and students will learn about the geological eras, and how life appeared and adapted throughout each of the geologic eras.
Some of Earth’s magnificent landforms are caused by erosion and weathering. But what is erosion and how does it change the Earth’s surface so drastically? This Miniclip explains the process of erosion including the various mechanisms such as water, wind, ice, and mass movement; defines sediment and deposition as part of this process; and explains how human influence has increased its prevalence through global warming and deforestation. Show Less
Some of Earth’s magnificent landforms are caused by weathering and erosion. But what is weathering and how does it create magnificent structures on our planet? This Miniclip explains the process of weathering including the two main types: mechanical and chemical. Students will learn the different natural impacts on this process such as water, temperature change, wind, oxidation, and more. Show Less

This programme is about seawater. It is the most important liquid on Earth, not only from its sheer volume, but also because it has remarkable qualities. A few of them, like buoyancy, are common to all liquids - but seawater is also the cradle of life. Three key factors of water underpin life in the sea: water’s dissolving power, its tendency to keep a stable temperature, and its transparency to light. This programme explains the mechanisms and the outcomes of these key facts—and other things—that make seawater both weird and wonderful. Show Less
"Land and Ocean" examines who the world's land masses and oceans affect global climate patterns. We look at why the air gets colder and colder the higher you go, why coastal regions don't heat up or cool down as much as inland regions, why winters are colder in the northern hemisphere, and a whole lot more Show Less
In this episode, we describe how tropical cyclones form and examine their huge power. We explain what the Coriolis effect is and how it make tropical cyclones rotate the way that they do. We also travel to three continents to demonstrate how Coriolis effect affects water draining from a small container. Does water really swirl in a different direction depending on which hemisphere it is in? Show Less
"Following the Sun" looks at how the sun's movement across the sky every day changes. In summer, the sun reaches a much higher angle in the sky than it does in winter. This affects the design of energy-efficient homes and the placement of solar panels. Show Less
In the first episode of this series, we briefly look at how the changing seasons affect life on our precious Earth and then examine what causes seasons, the turning of the days, and the three main climate zones.
In "Long Hot Summer Days" we explain why summer days are long and winter days are short, and how the length of daytime contributes to seasonal variations in temperature.
