Answer:
d. Temperate regions have weak thermoclines (moderate in summer, less in winter)
Explanation:
The theromoclines and how strong they are are crucial for the movement and exchange of nutrients between the surface waters and the deeper waters. The nutrients are mostly found in the deeper and colder waters, so they only reach the surface and shallower waters when the thermoclines are weaker. With the movement of the nutrients toward the surface waters, they provide nutrition for the marine organisms, resulting in much larger populations and much more species to be present. The temperate regions are the ones where the theromoclines start to become weaker because the waters become cooler, especially in the winter when the temperatures are much lower and the waters become colder as well.
Answer:
place, space, and scale
Explanation:
A geographer investigate issues from the view point of location according to place, space and the scale.
The place is an element of location that describes the position or the domain of occurrence of issue.
Space refers the area occupied by a body or the area where an issue is domiciled.
The scale refers to the magnitude at which an issue is view or observed.
Geographers tends to synthesize and combine these different lenses to observe and investigate an issue. Almost everything on earth can be correlated spatially using these lenses.
