That statement is true
an HR Diagram would plotted the absolute magnitude of the stars against their color. The resultant plots of this diagram showed that the relationship between the luminosity and temperature of the Star are not Random
B) Infiltration from surface to the soil and then it percolates through the soil down to the bedrock and water table
"The lithosphere is subdivided into tectonic plates. The upper part of the lithosphere which chemically reacts to the atmosphere, hydrosphere and biosphere through the soil forming process is called the pedosphere. The lithosphere is underlain by the athenosphere which is the weaker, hotter, deeper part of the upper mantle."
