Answer:
Visible Light Absorption
Atoms and molecules contain electrons. It is often useful to think of these electrons as being attached to the atoms by springs. The electrons and their attached springs have a tendency to vibrate at specific frequencies. Similar to a tuning fork or even a musical instrument, the electrons of atoms have a natural frequency at which they tend to vibrate. When a light wave with that same natural frequency impinges upon an atom, then the electrons of that atom will be set into vibrational motion. (This is merely another example of the resonance principle introduced in Unit 11 of The Physics Classroom Tutorial.) If a light wave of a given frequency strikes a material with electrons having the same vibrational frequencies, then those electrons will absorb the energy of the light wave and transform it into vibrational motion. During its vibration, the electrons interact with neighboring atoms in such a manner as to convert its vibrational energy into thermal energy. Subsequently, the light wave with that given frequency is absorbed by the object, never again to be released in the form of light. So the selective absorption of light by a particular material occurs because the selected frequency of the light wave matches the frequency at which electrons in the atoms of that material vibrate. Since different atoms and molecules have different natural frequencies of vibration, they will selectively absorb different frequencies of visible light.

Another way to describe location is to use reference lines to describe coordinates, or absolute position, on the globe. Two types of imaginary reference lines are used to locate positions or points and to make accurate globes and maps. These lines are called parallels of latitude and meridians of longitude.
Latitude and longitude make up the grid system that helps us identify absolute, or exact, locations on the Earth's surface. You can use latitude and longitude to identify specific locations. Latitude and longitude are also helpful in identifying landmarks.
A. Correlation coefficient is simply just a number that shows the strength of the correlation. (ranges from -1.0 -> +1.0)
Answer:
The answer would be B
Explanation:
Higher temperatures and an increase of rainfall, increases the overall effect of weathering and through that, the extent of soil development. Order of events: Increase of rainfall, increase of organic matter content, decrease in pH, increased leaching of basic ions, and movement of clay.
