The abiotic spheres—comprising the lithosphere, atmosphere, and hydrosphere—are made up of non-living components. Abiotic factors include elements such as minerals, gases, and water, all of which do not originate from living organisms. These spheres interact with each other and influence the Eart...

A warmer planet doesn’t just raise temperatures. From wildfires to flooding to coral bleaching, here are some real-world implications.
could be alone in the universe. The first reason Earth was able to become this welcoming blue sphere is because it's at just the right distance from the Sun, in a narrow zone not too hot and not too cold, where the temperatures are compatible with liquid water and life....
We identified three major strands of delta scholarship which are briefly discussed below in order to set the scene for the systems research that we focus on in the remainder of the article. The first strand of delta research looks at mitigating the impact of nature on delta societies through ...
So could it be that Earth really is unique? All living things on Earth are made of the same building blocks, long carbon-based molecules.所以地球真的是独一无二的吗？地球上所有的生物都有着相同的组成成分，即长碳基分子。Scientists now think that a large proportion of these molecules came from...
GPS, or the Global Positioning System, is a global navigation satellite system that provides location, velocity and time synchronization. GPS is everywhere. You can find GPS systems in your car, your smartphone and your watch. GPS helps you get where you are going, from point A to point ...
GNSS are more than the satellites orbiting Earth. The multiple groups of satellites, known as constellations, broadcast signals to master control stations and users of GNSS across the planet. These three segments – space, control and user – are all considered part of GNSS. But most frequently...
Overall energy use can have a major impact on the environment. Today, fossil fuels are the primary source of energy for most individuals, businesses, and industries. However, their combustion is a significant source of greenhouse gas emissions and may contribute to other environmental problems such...
The requested information then travels in reverse order through the same path, from the Earth station to the satellite, and down to the user’s dish. In general, low-Earth orbit (LEO) satellites, which are relatively close to the surface of the planet, provide less latency than high-orbit...
