Why does moon's highest altitude change during the year I came across a question in which moon's highest altitude had to be calculated as seen from a certain latitude, also the month and the hour and the constellation in which moon would be in had to be calculated......

I could not understand why or how would moons path change during the year
The moon's orbit around the Earth is inclined at about 5° to the ecliptic 
So as the Earth progresses in its own orbit around the sun, the moon's altitude also changes 

During summers the part of the orbit on the other side of the Earth(night side) is below the ecliptic. While during winters it is the upper part which is on the night side
