Among all these options, the best one is C. nation. Country or state are defined by the power and borders rather than shared culture, and not all nations even have a country (e.g. Kurds).
Answer:
Inclined layers in sediment or sedimentary rocks that reveal the direction of wave or wind transport
Explanation:
In geology, cross-bedding or cross-beds refer to sets of beds that are inclined relative to one another (they are at an angle compared to the main bedding plane).
The beds are inclined in the direction that the wind or water was moving at the time of deposition. Therefore, these ripples indicate that there was water of wind in the environment when they were formed.
They are very common in beach deposits, sand dunes, and river deposited sediment.
Thus, the correct answer is "<u>Inclined </u>layers in sediment or sedimentary rocks that reveal the direction of <u>wave or wind</u> transport"
