Answer:
Spot (4) Has evidence that there were waves here at some point. It looks as if the sand/surface debris was moved back and forth, creating this pattern in the sand. Spots (5) and (7) show evidence of water erosion. The smooth edges of both hills mean that water once flowed through that area, carrying little pebbles and rocks that gradually shaped and smoothed those mounds. An example for this would be how there are smooth areas in the Grand Canyon where scientists have concluded that some, if not all, of the Grand Canyon was formed by flowing water. "Rapid uplift, cracking, and surface drainage of receding floodwaters provide both the path and the necessary volume of water to quickly carve out Grand Canyon," says scholars on icr.org.
Explanation:
Water Erosion exists.
Answer:
The answer to your question is Yes, it is spontaneous
Explanation:
Gibbs free energy is the sum of the enthalpy plus the product of the temperature and the entropy of the system.
G = H - TS
The sign of the Gibbs free energy of a reaction determines if the reaction is spontaneous or nonspontaneous.
If ΔG > 0 the reaction is non-spontaneous
If ΔG < 0 the reaction is spontaneous
In this question ΔG = -136 kJ, then it will be spontaneous.
It’s occasionally used to remove static electricity in machinery or dust from photographic film. it can be used as a lightweight heat source for thermoelectric power in space satellites.
