What is the Earth's average surface temperature? How thick is Earth's crust? How many layers are in the Earth's crust? How deep does the Earth's crust go? How much iron is in the Earth's crust? How far is the Earth's outer core from the crust?
destroyed forests and Earth's temperature increase. Others may investigate the "what" rather than the "why" of things. For example, ecologists build models to estimate gray wolf abundance in Montana, U.S. It's impractical to spot them all and count them. Abundance. models are not 100 ...
It is frequently stated in textbooks and scholarly articles that the surface temperature of Earth is 33°C warmer than it would be without the atmosphere and that this difference is due to the greenhouse effect. This Forum shows that the atmosphere effect leads to warming of only 20°C. This...

1. There is more stuff (matter) that we don't see with our telescopes. We call this dark matter. 2. Newton's laws and even GR are wrong on the scale of galaxies and everything bigger. This idea is usually called modified gravity (because we need to modify GR) or Modified Newtonian...
"That heat index equation which everybody uses is actually not completely representative of how the air is going to affect your body," Carfagno said. "So this wet bulb globe temperature is a really good measure of how the heat could affect someone's body because it doesn't even worry abou...
Gamma-ray bursts reveal largest structure in the universe is bigger and closer to Earth than we knew: 'The jury is still out on what it all means.' By definition, the universe is everything in existence, so nothing can exist outside it. That said, modern theories such aschaotic inflation...

space (good news for life on the planet). In a paper presented in 1895, Arrhenius figured out that greenhouse gases such ascarbondioxide could trap heat close to theEarth's surface, and that small changes in the amount of those gases could make a big difference in how much heat is ...
