The data table shows the years when Halley’s Comet was closest to the Sun, making it visible to observers on Earth.

Based on the data table, the next year when Halley’s Comet will most likely be visible to an observer on Earth would be

• 2022

• 2043

• 2061

• 2136

The data table shows the years when Halley’s Comet was closest to the Sun, making it visible to observers on Earth.

The reason that Halley’s Comet can be seen during specific years is that

• the orbit of Halley’s Comet is a perfect circle

• the orbit of Halley’s Comet is controlled by Earth’s gravity

• Halley’s Comet orbits Earth in a cyclic and predictable pattern

• Halley’s Comet orbits the Sun in a cyclic and predictable pattern

The diagram below represents Earth’s polar and equatorial diameters, measured in kilometers (km). The shape of Earth is best described a

• perfectly spherical because the equatorial diameter is the same as the polar diameter

• perfectly spherical because the equatorial diameter is slightly larger than the polar diameter

• nearly spherical because the equatorial diameter is the same as the polar diameter

• nearly spherical because the equatorial diameter is slightly larger than the polar diameter

The diagram below represents Earth’s layers, labeled A through D.

The darkly shaded areas of the map represent regions with a high potential for earthquakes to occur. Letters A through D represent locations on Earth.

Earthquakes that occur on the ocean floor may produce tsunamis, which are large ocean waves that can flood coastal locations. Which location is most likely in the greatest danger from a tsunami?

The darkly shaded areas of the map represent regions with a high potential for earthquakes to occur. Letters A through D represent locations on Earth.

Scientists infer that the major cause of most earthquakes is the movement of

• glacial ice due to unequal heating of Earth’s surface

• shorelines due to faulting of rock layers on Earth’s crust

• lithospheric plates due to convection cells in Earth’s mantle

• continents due to increased greenhouse gases entering Earth’s atmosphere
