So now, if we've got clay and humus, these transformed materials, and we mix them together, we've got something very close to soil. But soil isn't static, and there're still other processes that go into the formation of soil: the movement and loss of materials. ...
Earthquakes What causes earthquakes The earth is formed of layers. The surface of the earth, about 100 kilometers thick, is made of large pieces. When they move against each other, an earth quake happens, A large movement causes a violent earthquake, but a small movement causes a mild one...
However, advances in seismology have allowed us to learn a great deal about the Earth and the many layers that make it up. Each layer has its own properties, composition, and characteristics that affects many of the key processes of our planet. They are, in order from the exterior to the...
Earth science concentrates on investigating how the planet works and why. This field delves into the many layers of the Earth and explains how those pieces fit together into a cohesive structure. The interdisciplinary subject not only provides insight into the mechanics of the solid parts of the ...
Our interest is in the way the earth’s biosphere and its ecosystems might change over time. We are not classifying this as climate change because in view of the history over the last 20 years, it is an unhelpful abstraction. But we are interested in the behaviour of droughts, floods, se...
Geography is the study of Earth and its climates. Scientists use it to study global warming and track the weather. Governments use it to learn where people live and work and to plan what to do with the land. It is now easier than ever to use geography because of a science called space...

Earth’s inner core, made of solid iron and nickel, is roughly two-thirds the size of the moon. The researchers used machine learning to pinpoint the most accurate model of the strange physical processes that shape our planet's inner core. Earth’s core is a strange, strange place. Fo...
While each pore space is tiny on its own, there are so many that their collective volume can easily accommodate large quantities of water. There are two kinds of aquifers: unconfined and confined. A confined aquifer means that it is bounded by impermeable layers above and below, so ground...
At any rate, let’s get back to Search Queries 101. There’s an astounding number of search terms being entered in search boxes (and by using digital voice assistants and voice-search apps). Google processesroughly 100,000searches everysecond. And that’s just Google. ...
