Question

When logging is carried out in a watershed, a likely effect on the local stream is:

A. increased water temperature

B. increased oligotrophic conditions

C. decreased input of sediments decreased nutrient levels

D. mitigation on anoxia

Answer 1

correct option is A. increased water temperature

Step-by-step explanation:

solution

we know as logging resulted in increased temperature as when watershed is partially clear cut or logging completely then decreased concentrations of dissolved oxygen and clear cut also reduced forest cover that also increase temperature

and generally by deposition of fine sediment in the gravel also carried out logging

so here correct option is A. increased water temperature

Answer 2

A. increased water temperature

Step-by-step explanation:

The extraction of wood near a hydrographic basin implies the reduction of trees in that region. As we know, a large concentration of trees has the power to decrease temperatures from the sun, for this reason, regions that have bodies of water and many trees have lower evaporation rates, due to the reduced temperature.

Based on this, we can affirm that the extraction of wood near a hydrographic basin will decrease the number of trees, which will promote an increase in temperature that will increase the water temperature.
