Explain the importance of the carbon cycle. What geologic evidence do we have to determine the spreading rates of the oceanic plates over Earth's history? Explain the term Crystal system in detail. Why are fossils only found in sedimentary rocks? Define what is an 'interstital impuri...

The atomic mass or atomic weight of an element (or put it in simple term, mass of an atom) is found by addingnumber of neutronsand number of protons. In calculating the atomic mass of an atom, the number of electrons and daltons are usually...
stable isotopeIn the Ohio River (OR), backwater confluence sedimentation dynamics are understudied, however, these river features are expected to be influential on the system's ecological and economic function when integrated along the river's length. In the following paper, we test the efficacy ...
You make an even larger, unstable radioactive isotope of uranium, uranium-236, that promptly splits into two smaller and more stable atoms krypton and barium (3). In the process, heat energy is released and there are three spare neutrons left over (4). The neutrons can go on to react ...
(e.g. at rates in the order of 10 m per year)27. Nonetheless, dynamic models of seafloor spreading show that it is difficult to maintain the required conditions of high permeability in the upper part of the asthenosphere without extracting more melt than the isotope data supports51. One...
We also quantified leaf carbon isotope ratio, which was closely related to plant long-term water use efficiency. Importantly, we measured traits of the same fern species in each successional forest separately to ensure that intra-specific variation was appropriately incorporated into our analyses. ...
