• a third quarter moon

The diagram shows the relative positions of Earth, the moon, and the sun. The moon is shown at four possible positions around Earth. Which position of the moon could result in a solar eclipse?

Taylor and Jose pulled their boat up onto the beach and went on a hike. When they returned, the beach was covered by water and the boat was floating offshore. What is the most likely explanation?

• The low tide receded and pulled the boat out to sea.

• The spring tide came early.

• The gravitational pull of the sun and moon decreased the tidal range.

• The water level rose due to the high tide.
