Explanation / Answer

1. Please attach the image for the question.

2. A. Coal burning in the mid-western states.

The dust from the mod-western states is brought to eastern states by the prevailing wind direction.

3. A. Confined

The layer which is sealed from top and bottom and receives the water from far away point is known as confined aquifer

4. The Sun

5. The cycle through which the carbon is exchanged in biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth is known as carbon cycle. This is a biogeochemiical cycle. Since the industrial revolution the carbon dioxide in the atmosphere is 39% increased in the atmosphere.This shows that the carbon exchange is largely impacted by the use of fossil fuels and after industrial revolution we are producing more and more carbon footprints.

6. B. Original Horizontality

Steno's principal of original horizontality

7. D. the bending of P- and S-waves as they enter denser rocks

Refraction is the phenomenon where the bending occurs. Some of the wave is reflected and rest passes through with slight change in angle with respect to projection which we call refraction.
