I believe the answer is "D"
The U.S. has more than 87,000 dams greater than six feet high (and two million overall). While many dams continue to provide benefits such as flood control, irrigation, and water supply, for other dams the cost of maintenance or the negative effects on communities, fish, and tribes justifies their removal.
Dam owners and regulators decide whether to remove a dam by weighing many factors including: the cost of removal and the ability to replace any lost power generation against avoided long-term maintenance; safety concerns; benefits to endangered fish populations; increased recreational and commercial fishing; and restoration of cultural values of nearby tribes.
By 2020, roughly 70% of dams will be more than 50 years old, inviting us to reconsider the value to the public of long-term investments in this infrastructure.

Answer:
Explanation:
1. glacial tills and cirques Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial, and ground moraine. Cirques form by the accumulation of snow and ice avalanching from upslope areas. The size of cirque glaciers ranges from glaciers that are completely limited within hosting bedrock hollows, to glaciers that form the heads of large valley glaciers.
2. ENERGY FROM THE SUN heats up the air at the equator most because of the curvature of the earth. This tends to rise up then head toward the poles where it cools and moves closer to the surface and then more or less back toward the equator.
THE ROTATION OF THE EARTH makes the movement of air relative to the surface of the earth seem to deflect. This Coriolis effect doesn't affect your toilet flushing, but does influence large scale wind patterns and hurricanes.
THE LATITUDE OF VANCOUVER roughly half way between the equator and the north pole positions us so the large scale wind patterns tend to bring us winds from the west.
THE PACIFIC OCEAN sits to the west. Winds pick up moisture from it toward shore. Large bodies of water also tend to hang on to energy that keeps our temperatures more moderate.
THE COAST MOUNTAINS push the moist air upward so it cools off and can't hold on to as much moisture, so it rains.
THE TILT OF THE EARTH'S AXIS relative to the plane of our orbit around the sun means we are tilted away from the sun during winter, so it's cooler. This results in a greater temperature gradient between the equator and the north pole, and the winds get stronger. The cooler temperatures combined with more moisture-ladened wind brings more rain during winter.
