A tornado forms when there is a hot layer of atmospheric air that is covered by a relatively cold, dry bank of air above. When the warm air at the bottom of the atmosphere rises (due to its temperature), it pushes up on the cold air...

Zebras are actually black with white stripes. All animals get their colors from pigments called melanin which are of two kinds - eumelanin gives a black to brown color which pheomelanin gives reddish to yellow hues. The cells that create...

Friction is the resistance that one object or surface experiences when moving over another object or surface. The two types of friction that come into play when moving two objects against one another are static and kinetic. Static...

Most of Humanity is in India and China because the ratio of human survival and occupation of the planet has always been similar, but modern advancements have allowed those numbers to increase exponentially, so the difference has become...

The hottest parts of the world do not lie on the Equator (as our assumption would suggest) but rather around the tropics, i.e., the areas that lie above and below the Equator. Whats the reason behind this? The answer to this question...

This video introduces viewers to the concept of biomes, showcasing different types such as tropical rainforests, savannas, deserts, and tundras. Through engaging dialogue and examples of animals and plants found in each biome, the video...

We’ve talked about how housing is important for health. We’ve talked about how we can improve access to housing through stimulation of production through the LIHTC. We’ve talked about how we can improve access through vouchers and...

Deserts are regions that receive very little precipitation each year, but how are they formed? The unique characteristics of the world's deserts, from hot to polar. Earth Science - Weather - Learning Points. Deserts are the driest...

Why is conservation important? How can we conserve biodiversity and wildlife species? Biology - Ecosystems - Learning Points. Conservation helps prevent organisms and habitats being lost. Protection is the best approach to conservation,...

What causes different kinds of weather? What is wind and where does it come from? How can pressure systems help us predict the weather? Earth Science - Weather - Learning Points. Understanding weather systems is the key to reliable...

Where and when an earthquake will strike remains one of geology's greatest mysteries. Could modern science ever predict them? Earth Science - Geology - Learning Points. Where and when an earthquake will strike remains a mystery. Most...

Urban environments may seem very different from one another – but their underlying structures are often remarkably similar. Human Geography - Orientation And Settlements - Learning Points. Every urban settlement has a central business...

Offshore oil spills can lead to decades of ecological harm for marine life. How can we clean-up oil spills and limit damage to the environment? Earth Science - Human Impacts - Learning Points. Offshore oil spills float on the surface of...

The legendary El Niño effect causes dramatic shifts of weather, resulting in droughts and floods across the globe. It can all be traced to winds dying down over the Pacific ocean. Earth Science - Weather - Learning Points. El Niño is a...

A look at the Burgess and Hoyt models, and how each explains the layout of urban settlements. Human Geography - Orientation And Settlements - Learning Points. The Burgess Model shows a city's development as a series of concentric rings,...

Cities near fault lines are at high risk of earthquakes. Can earthquakes be predicted, and how can these communities prepare for the worst? Earth Science - Geology - Learning Points. Cities near fault lines are at high risk of...

Scientists have found a way to make it rain. But weather modification has its critics, and there may be unforeseen consequences surrounding the "cloud seeding" process. Earth Science - Weather - Learning Points. When silver iodide is...

We create a Rubens\u2019 Tube to demonstrate the movement of sound waves. A tube lined with holes is filled with propane and connected to a speaker. We light the gas coming from the holes and play different frequencies and volumes of...

The Amazon rainforest is being cut down for resources and land at a rapid rate. Learn how alternative farming methods, incentives to cut carbon emissions and protected reserves are helping to conserve the rainforest from further harm....

Deciduous forests are found in more temperate climes and are home to a wide variety of plants and animals. What can we do to limit our impact on these ecosystems? Earth Science - Human Impacts - Learning Points. In the UK, deciduous...

Rural-urban fringes represent transition zones, where the demands between traditional rural life and urban expansion compete. What are the major land uses in this area? And what debate exists around development? Human Geography -...

Around the world monsoons bring huge volumes of seasonal rain to certain regions. The best known is the Asian monsoon, but why does it happen? Earth Science - Weather - Learning Points. Monsoons are heavy rainfalls concentrated over the...
