Answer:
Deep ocean currents.
Explanation:
In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.
The freshet is basically a flood that occurs because of heavy rainfall or because of the melting of a snow.
This type of flooding is most common in the valleys of the larger rivers, especially the ones that start their flow high in the mountains.
The large rivers have much more water, and they also have lot of tributaries, so when there's a heavy rainfall they receive enormous amounts of water, which easily causes a flood.
Also, when the snow melts, lot of water is released from it, and most of that water gets into the river, or first in its tributaries and that in it, so there's a high possibility of a big flood occurring suddenly.

Answer:
The amount of tectonic activity along the margin
.
Explanation:
<u>Margins are categorized as passive when the tectonic activity along it is poor.</u> This is manifested through rare to non-existent <em>earthquakes</em> and <em>volcano eruptions</em> in the area.
On the other hand, <u>active margins are characterized by frequent tectonic activity.</u> This means <em>mountain formation, earthquakes, and volcano activity</em> are not strange here.
Contagious diffusion is wide-spread and involves interpersonal contact.
