Which of the following developments would most likely occur if average summer air temperatures in the Arctic increased by 4°C? A. Increase in permafrost thickness

B. Increase in mosquito populations

C. Reduction in grazing animal populations

D. Reduction in land-based predator populations
Please

A. Increase in permafrost thickness

Explanation:

Climate warming (like of 4°C) would increase the active layer thickness (ALT) of permafrost, which can cause changes in the hydrological cycle, ecological processes, and carbon flux in cold regions.

answer: a tank of height h is filled with water and sits on the ground. water squirts from a hole at a height y above the ground and has a range r. for two y values, 0 and h, r is zero. determine the value of y for which the range will be a maximum.

explanation:

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
