Answer:
wave base is the highest depth at which the route of a water wave creates substantial movement of water.
Wave height is the lateral distance between the waves and the wave's crest
Explanation:
In physical oceanography, the wave base is the highest depth at which the route of a water wave creates substantial movement of water. For water depths greater than the base of the wave, the underlying sediments and the seabed are no longer disturb by the above wave motion.Wave height is the lateral distance between the waves and the wave's crest from taken from bottom of the trough.
A. expanding the copra trade.
The correct answer for this question is option C
Answer:
C. Physical
Explanation:
The Rio Grande river is an example of a physical boundary between two countries since it is a landform. Physical boundaries are very diverse and can include oceans, seas, mountains, rivers, and lakes, just to name a few of the many landforms that can make a physical boundary.
A cultural, geometric or religious boundary could perhaps be visible with the right type of map, but a river does not tell us anything about the religious makeup of a certain area, nor does it reflect the cultural of the inhabitants.
Fossil records from separate continents, particularly on the outskirts of continents show the same species. As well mineral specimens along the supposed break lines of the continents are nearly identical. Some identical species exist on certain continents, like an earthworm common to both Africa and South America suggesting the species could not have spontaneously arisen on both continents without some variations.
