Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
This chapter discusses various energy sources. It introduces and discusses relevant physical and chemical properties of the earth's core studied from seismology, shock-wave data and core composition, and the thermal regime. The basic equations and conventional laws are set out and local equations, global energy balance, global entropy balance, and the magnetic field strength to the power supply are discussed. The possible power sources—radioactive heating, primordial heat and freezing of the inner core, gravitational energy release and adiabatic heating, chemical effects such as the heat of reaction between components, and precession and tidal forcing—are also explained. The chapter then summarizes the results from dynamo theory, freezing of the liquid in the outer core, and boundary layers, effects of stable density stratification. Finally, the thermal history of the Earth is outlined.
