It’s mid afternoon and you are canoeing down a river that empties into a large lake. You are having a hard time making progress because of a stiff wind in your face. Is this situation likely to get better or worse at sunset? Explain.

The wind should die down at sunset


When the sun beats down on the surface of the earth, a lot of energy is absorbed. When that heat is released, it increases the kinetic energy of the air around it. So, that's why the wind often blows during the day.

When the sun sets, the kinetic energy due to that release of heat decreases, and the winds generally get calmer.
