After doing a lot of research and looking at the graph above, I did this on paper and have got the answer for you. However, since I can't draw iny our book myself, I am going to explain where you can draw a line to show the changing length of daylight over the course of one year that occurs for an observer at 50° S latitude.
You will need to have a line that extends from the beginning of January to the end of December. the line needs to be marked anywhere from the graph line 16 that goes downward to line 12, 8, then curves upward towards line 12 and ends at line 16 on the other side of the graph. If you need more help or don't understand, I can try to get you a picture uploaded. It isn't letting me at this time for some reason, I keep getting an error.
ANSWER: geologic processes have destroyed or shrouded most of them.
Geology is a field much smaller than geography, and it is a sub-field of geography. Geology is only concerned with the solid material on Earth: the rocks.
Geography is concerned with rocks, but it's also concerned with liquids, gasses and living creatures and their interactions with each other.
It is the windward side. This side expierences these low temperature because of the wind while the other side dosent have wind at all.
