This is soil, just ordinary soil. The most
important layer of material on our planet. My name is Russell Lawley and I am a geoscientist
here at British Geological Survey. All the food we eat is grown in soil. All the water
we drink is filtered by soil. Life on Earth wouldn’t happen without it. All soils contain a mineral component, which tends to come from the geology, a biological component, and they all they
all contain air and water. My role is to try and help other scientists understand the role of geology and its influence on soil, the features and characteristics that make these
soils behave in a particular way, to build up a better understanding of how we can use
soils and we can get more from them over time.
