    Base your answers to questions 2 on the diagram below and on your knowledge of Earth science. The diagram represents Earth’s revolution around the Sun. Points A, B, C, and D represent Earth’s positions in its orbit on the first day of each of the four seasons. The major axis and the foci (the center of the Sun and the other focus) of Earth’s orbit are shown.

    Base your answers to questions 7 on the diagram below and on your knowledge of Earth science. The diagram represents a portion of a stream and its surrounding bedrock. The arrows represent the movement of water molecules by the processes of the water cycle. The water table is indicated by a dashed line. Letter A represents a water cycle process occurring at a specific location. Letter d represents the distance between the water table and the land surface.

    Base your answers to questions 10 on the diagram below and on your knowledge of Earth science. The diagram represents a planetary system, discovered in 2013, with seven exoplanets (planets that orbit a star other than our Sun) labeled b through h orbiting a star. The exoplanet orbits are represented with solid lines. For comparison, the orbits of three planets of our solar system are shown with dashed lines. The sizes of the star, exoplanets, and planets are not drawn to scale.

    Base your answers to questions 11 on the block diagram below and on your knowledge of Earth science. The block diagram represents a region of sedimentary rock that has been intruded by magma, which has since solidified. Points X and Y identify locations at the boundary between the igneous intrusion and surrounding sedimentary rock layers. Letters A and B represent specific rock units. Letter C represents rock formed from the lava flow of the nearby volcano. The rock layers have not been overturned.
