6 0

It is widely accepted that the Earth’s interior is composed of several layers: the crust, the mantle and the core. Since the crust is readily accessible, scientists have been able to perform hands-on experiments to determine its composition; studies on the more distant mantle and core have more limited opportunities samples, so scientists also rely on analyses of seismic waves and gravity, as well as magnetic studies.

Measuring Seismic Waves

It is impossible to drill to the center of the earth, so scientists rely on indirect observations of matter lying below the surface through use of seismic waves and their knowledge of how these waves travel during and after an earthquake.

The carbon cycle is one of earths natural resources that enables all living organisms to inhabit the planet. For example, with out this vital resource we would run out of oxygen. Flora (plants and trees) use the carbon that is a by product of cellular respiration by fauna (humans and animals) to reproduce oxygen and this cycle continues. which is what keeps all living organisms in harmony and alive.
