You are digging a hole in you backyard when you see a a piece of fossilized bone in the dirt. how could you prove the age of the fossil? design a procedure for determining the relative and absolute age of the bone.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

its temperature is increasing. this causes molecular vibrations to increase.
