    Eccentricity Rate Gradient Standard Error
    Base your answers to questions 1 on the diagram below and on your knowledge of Earth science. The diagram represents one position of Earth in its orbit around the Sun and 12 constellations that can be seen in the night sky by an observer in New York State at different times of the year. The approximate locations of the constellations in relation to Earth’s orbit are shown. Point A represents another position in Earth’s orbit.

    Base your answers to questions 10 on the passage and data table below, which describe the exploration and characteristics of one of Saturn’s moons, Titan.

    Huygens Probe Lands on Titan

    The Huygens probe was carried to Saturn by the Cassini spacecraft and parachuted to the surface of Saturn’s giant moon, Titan. The Huygens probe’s landing site was littered with smooth, rounded, rocklike objects. Photographs taken of Titan’s surface show drainage channels leading to an apparent shoreline. The question is, what are they draining? One of the photographs seems to show ground fog consisting not of water, but perhaps of ethane or methane.

    Base your answers to questions 12 on the passage and data table below and on your knowledge of Earth science. The data table shows the apparent hourly change in the direction of a pendulum’s swing, in degrees per hour (°/h), for six different Northern Hemisphere latitudes.

    Foucault’s Pendulum

    In 1851, Jean-Bernard-Léon Foucault attached a heavy iron ball to a steel wire hanging from the high ceiling of a church in Paris to demonstrate an apparent motion caused by Earth’s rotation. This pendulum could swing freely back and forth. A spike on the bottom of Foucault’s pendulum produced straight lines in sand spread on the floor. The position of each new line appeared to gradually shift in a clockwise direction. Eventually, the pendulum returned to its original path, completing a 360° pattern in approximately 32 hours. At other northern latitudes, a Foucault pendulum will complete a 360° pattern of swing in different amounts of time. In the Northern Hemisphere, the number of degrees that a pendulum appears to change its clockwise direction of swing each hour varies with latitude.
