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

There are almost eight billion people in the world, and one of them is you! But what if there were only 100 people, what would life on Earth look like? Let’s create a micro-world of our own, populated by only 100 people and find out. How many people would be from Asia? How many from North America? Would everyone in our micro-world have somewhere to live? Resources like money, how would it be distributed? In this film, we will use simple statistics to describe our world. Show Less

In the sea life is everywhere, but five habitats are like underwater cities. They are coral reefs, mangroves, salt marshes, sea grass beds and kelp forests. They provide safety, food, and a nursery for the young of many species. Yet they are in critical danger because we humans are rapidly destroying them. This programme seeks to explain why these five habitats are very important to life in the sea and to point to the fact that they are all in decline. They are being damaged by human activity... some are being cleared away for ports or housing, some are damaged by trawling nets or dredge silt, as well as pollution, overfishing, or the slow but undeniable outcomes of global warming... to name only a few of the reasons. We need to try and stop this worrying trend. Show Less

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

Heat waves, tropical cyclones, droughts, tornadoes, hailstorms, floods, and severe thunderstorms. These are all examples of extreme weather that shape our landscape. But what exactly are they and how do they happen? This Miniclip explores each of these extreme weather types and examines the natural and human influences that cause them including climate change, the Earth’s atmosphere, ocean currents and more.

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

The main causes of air pollution are natural and human pollutants. Gases emitted in the atmosphere due to volcanic explosions and forest fires are natural pollutants, while gases like sulphur dioxide, nitrogen oxides released from industries, carbon monoxide, carbon dioxide, lead released from automobiles and chlorofluorocarbons released from household consumption are human pollutants. Show Less

During the day, due to the strong sun, the air above the surface of the earth gets heated and rises, creating a region of low pressure in that area. When the warm air reaches the upper levels of the troposphere, it gets cooled, sinks and rushes down, setting convection currents in motion. This causes winds to blow. Show Less

There are three major types of rocks, namely, igneous rocks, sedimentary rocks, and metamorphic rocks. These rocks undergo change, from one type of rock into another, under certain conditions. This change happens in a cyclic manner and is known as the rock cycle. Show Less

Coal is a fossil fuel and mainly consists of carbon and small amounts of hydrogen, sulphur, oxygen and nitrogen. Heating coal, in the absence of air, is known as destructive distillation of coal. It yields various useful products like coke, coal gas, coal tar, and ammoniacal liquor. Show Less
