Which statement best explains the apparent sinking of this sailboat?

• The sailboat is moving around the curved surface of Earth.

• The sailboat appears smaller as it moves farther away.

• The tide is causing an increase in the depth of the ocean.

The map shows four major time zones of the United States. The dashed lines represent meridians of longitude. The locations of New York City and Denver are shown.

The basis for this time difference between adjoining time zones is Earth's

• 1^o per hour rate of rotation

• 24^o per hour rate of rotation

• 60^o per hour rate of rotation

• 15^o per hour rate of rotation
