I've always thought that the process of planetary accretion was energetic enought to keep the proto-Earth entirely molten, and that the subsequent evolution of the planet (the formation of the crust, ...

The plot above is about the concentration of siderophile elements in the terrestrial mantle.
From the logarithmic plot, we can deduce that the concentration of highly siderophile elements is quite ...

Today I saw a rainbow after almost a decade. I live in Noida (a city) in India. Most people I know believe that: we don't see rainbows nowadays because of pollution and now after nearly 3 months since ...

The climatic system can be divided into five main components: the atmosphere, the hydrosphere, the lithosphere, the cryosphere and the biosphere.
All these physical systems operate at different time ...

Why doesnt mankind "collect" thermal energy (there has to be some way: thermal couplings, detour over chemical energy, whatever) and after it has been concentrated at one point, turn it to electrical ...

There's a song "Blizzard's Never Seen the Desert's Sand". Given Antarctica is a desert, someone questioned the title's validity. BUT is there sand in Antarctica?
I'd imagine yes as it's a pretty ...
