This post delves into the long-term carbon cycle that involves the interactions of the atmosphere with rocks and oceans over many millions of years. Because of its length, I've broken it up into bookmarked sections for easy reference: to come back here click on 'back to contents' in each instance. Carbon dioxide and rock weathering: the chemistry.

Carbon is an incredible element. Arrange carbon atoms in one way, and they become soft, pliable graphite. Re-jigger the arrangement, and — presto! Carbon is also the key ingredient for most life on Earth; the pigment that made the first tattoos; and the basis for technological marvels such as graphene, which is a material stronger than steel and more flexible than rubber. Carbon occurs naturally as carbon, which makes up almost 99 percent of the carbon in the universe; carbon, which makes up about 1 percent; and carbon, which makes up a minuscule amount of overall carbon but is very important in dating organic objects.
How do scientists figure out how old things are?
It is no exaggeration to say that has been a dramatic and memorable year for the UK — and our weather and climate is no exception. We have experienced periods of record-breaking rainfall , record dry and sunny periods , and another notable summer heatwave. The remarkable year was also the third warmest in the long-running Central England temperature series from and the 18th wettest year in the long-running England and Wales precipitation series from Rainfall totals were particularly high across western Scotland and north-west England, so the UK series ranks higher than England and Wales.
Dendrochronology is the study of data from tree ring growth. Due to the sweeping and diverse applications of this data, specialists can come from many academic disciplines. There are no degrees in dendrochronology because though it is useful across the board, the method itself is fairly limited. Most people who enter into studying tree rings typically come from one of several disciplines:. Though dendrochronology also has uses for art historians, medieval studies graduates, classicists, ancient and historians due to the necessity to date some of the materials that the fields will be handling in their research projects.
