Ciara believes that whenever the Moon is in the position that
is shown from above (top view)
in Diagram A, the Moon always
looks completely dark in the
view from Earth, as shown in
Diagram B.
Is Ciara correct? If she is
correct, explain why the Moon
always looks dark from Earth in
that position, and explain how
she should show light in
Diagram A. If she is incorrect,
explain how else the Moon can
look when it is in that position.
