This video covers the Earth and Environmental science major and places an emphasis on earth science, soil science, geology, and hydrology. The Earth and Environmental Science major is a broad major that allows students a...

In this video Paul Andersen explains how water is unequally distributed around the globe through the hydrologic cycles. Seawater is everywhere but is not useful without costly desalination. Freshwater is divided between surface water...

Uncover the sustainable practices and historical challenges of a family-run oyster farm in Oregon. A compelling case study for students in environmental science and business studies.

The video discusses the importance of water on Earth and its distribution in different forms under the hydrosphere. It also highlights the various uses of water and emphasizes the need for water conservation. The video ends by...

Despite water covering 71% of the planet’s surface, more than half the world’s population endures extreme water scarcity for at least one month a year. Current estimates predict that by 2040, up to 20 more countries could be...

Water covers over 70% of the Earth, cycling from the oceans and rivers to the clouds and back again. It even makes up about 60% of our bodies. But in the rest of the solar system, liquid water is almost impossible to find. So how did our...

Water is refreshing, hydrating, and invaluable to your survival. But clean water remains a precious and often scarce commodity - there are nearly 800 million people who still don't have regular access to it. Why is that? And how can you...

Some plants can drink water from the air - and that has some weird effects on the forests where they live.

Water can dissolve more substances than anything else on earth...so why doesn't it dissolve everything away?

As organisms decompose their chemical and bacterial components can leach into the surrounding ground and water. The bodies buried in cemeteries are no exception.

For thousands of years, water was thought to be an element. That is, until some of the greatest chemists in the world managed to crack it open.

Fresh water accounts for only 2.5% of Earth's water, yet it is vital for human civilization. What are our sources of fresh water? In the first of a two part series on fresh water, Christiana Z. Peppard breaks the numbers down and...

Fresh water is essential for life -- and there's not nearly enough of it for the world right now. Why is that, and what could we do? Christiana Z. Peppard lays out the big questions of our global water problem. And no, shorter showers...

NSF-funded research expands on the Billion Oyster Project in New York Harbor, giving urban middle school students a hand in restoring oyster habitats



Description: Research consistently shows that children...

In this video, the speaker explains the concept of environment and its various components, including living and non-living organisms. They also discuss the four spheres that make up the planet Earth and how human activities are affecting...

In this video Paul Andersen explains how energy can be harnessed was water moves through a turbine. Three types of systems are discussed in the video; run-of-the-water, impoundment, and tidal. Several advantages and disadvantages of dams...

In this video Paul Andersen explains how soils are formed and classified. Weathering of rock creates particles which are mixed with water, air, and organic material. Soils are classified according to particle size, chemical makeup, and...

In this video Paul Andersen explains how biogeochemical cycles move required nutrients through the abiotic and biotic spheres on our planet. Matter on the Earth is conserved so producers must receive required nutrients through the water...

In this video Paul Andersen explains how the climate on the earth is affected by the amount of solar radiation and the greenhouse affect. The addition of anthropogenic greenhouse gases has led to global warming which is impacting humans...

In this video Paul Andersen explains how nuclear energy is released during fission of radioactive uranium. Light water reactors, nuclear waste, and nuclear accidents are also discussed along with the future of nuclear energy.

This video discusses the problem of environmental pollution and its three aspects: the introduction of contaminants, the extent to which they are present, and their harm to living beings and the environment. It also covers different...

This video discusses the problem of water scarcity and provides various measures that can be taken to address it, such as wise and judicious use of water, recycling and reusing water, and introducing efficient irrigation practices. The...

The video discusses the issue of water scarcity and its causes, particularly in India. It explains the different types of water scarcity and the indicators of a country facing water scarcity. The video also touches on the impact of...

The video discusses the water cycle, explaining how water changes from one form to another and how it is continuously replenished in nature. It covers the processes of evaporation, condensation, and precipitation and how they contribute...
