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.

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.

Rivers are a significant part of our natural landscape – they offer habitats for animals, support biodiversity, provide spiritual connections and much more. This Miniclip visits the United Kingdom's three longest rivers – the River Severn, the River Thames, and the River Trent. Students will discover geographical facts about each river, as well as how rivers are formed and why they are such an integral part of our natural world. 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

For many new agricultural technologies, feasibility issues need to be considered before they can be adopted by farmers and businesses. This video explains why scientific verification and practical adoption of technology are both important and discusses the long-term aims of new technologies, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. Show Less

New technologies in the agricultural industry can have environmental, social and economic impacts. This video explores the technology that targets methane emissions, how fruit yield and quality can lead to greater profitability and how commercial farmers actually interact with technology, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. Show Less

Agricultural processes have a large-scale impact on natural resources and ecosystems and many businesses are turning to technology to help. This video introduces some issues that agricultural technologies aim to address, including water scarcity, farm waste and sustainability, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. Show Less

Before agricultural technologies can be adopted by businesses, they need to be thoroughly tested and evaluated. This video looks at the techniques and systems researchers use to collect and evaluate data, such as internet-connected sensors and the SF6 tracer, with insight from scientists at agricultural research institutes. A highly relevant resource for middle to senior secondary students studying design technology, earth and environmental sciences or agriculture. 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

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

The calm appearance of a river in the middle course hides the fluvial processes at work under the surface. This video explains how landforms such as meanders and oxbow lakes are created through erosion and deposition and shows viewers the rapid transformative power of floods. Real footage and informative diagrams makes this essential viewing for GCSE geography students. Show Less

The River Severn, the UK’s longest river, is a perfect example of the transformative power of rivers on the landscape. This video takes viewers through the upper, middle and lower courses of a river, introducing key terms such as drainage basin, tributary, erosion, discharge and estuary. Real footage paired with informative diagrams makes this essential viewing for GCSE geography students. Show Less

As a river comes to end of its journey in the lower course, distinctive fluvial landforms emerge. This video explains how floodplains, levees and estuaries are created through deposition and shows viewers the transformative impact of changing water levels, through flooding and tides. A combination of real footage and informative diagrams makes this essential viewing for GCSE geography students. Show Less

As rivers journey from source to sea, they shape the landscape through a variety of fluvial processes. This video offers viewers in-depth explanations of erosion, transportation and deposition, covering the four types of erosion, the four types of transportation and the variety of landforms created through deposition. Real footage complemented by explanatory diagrams makes this key viewing for GCSE geography students. Show Less

The upper course of a river contains impressive landforms created from thousands of years of vertical erosion. This video explains how landforms such as waterfalls, gorges and interlocking spurs are created through the fluvial process of erosion, showing the effects of hydraulic action and abrasion. Real footage together with clear diagrams makes this essential viewing for GCSE geography students. Show Less

Despite how solid our planet's crust might feel beneath our feet, did you know that it’s actually changing all the time? This programme explores the composition of our Earth, how the surface is divided into tectonic plates, and the history of the movement of the tectonic plates including the supercontinent Pangaea. It also explains the different types of plate boundaries that exist and the different landforms that can be found at each of them respectively. Show Less

Why are earthquakes so dangerous and what can we do to minimise their impacts? In the final part of this series on earthquakes, students learn about the various dangers of earthquakes and their consequences, while also learning about the actions people can take in order to adapt to and live with these tectonic events.
