What is the name of the atmospheric layer closest to the Earth's surface? Which layer of the Earth is the coolest in temperature? How thick is the outermost layer of the Earth? What is the density of the Earth's mantle? Which layer of the atmosphere do we live in?
What elements comprise the largest portion of the Earth's biosphere? What is the upper mantle made of? What are the properties of Earth's inner core? What is the mesosphere mantle made of? What is the density of the Earth's mantle?

What is density? Mathematically speaking, density is the ratio of the mass to the volume. Physically speaking, density is the measure of how much matter is squeezed in a given space.The more matter is squeezed in the same space, the more dense....

One way is to think about theEarth's density(密度), Simon Redfern of the Universityof Cambridge in the UK told the BBC.“The density of the material on the Earth's surfaceis much lower than the average density of the wholeEarth, so that tells us there's something that has greater...
The Biosphere is made up of the parts of the Earth where life exists. It includes the land, ocean, and atmosphere. Life exists from9.5 km deepin the oceans up to50 km highin the atmosphere. Within the biosphere living things span a range of sizes, from the microscopic (like phytoplankton...
