Base your answers to questions 7 on the diagrams below. The diagrams represent the events that occur when a large meteor, such as the one believed to have caused the extinction of many organisms, impacts Earth’s surface. Diagram A shows the meteor just before impact. Diagram B represents the crater forming, along with the vapor and ejecta (the fragmented rock and dust) thrown into the atmosphere.

Which statement best explains how global climate would most likely be affected after this large meteor impact?

(1) Large quantities of ejecta in the atmosphere would block insolation and lower global temperatures.

(2) An increase in vapor and ejecta would allow radiation to escape Earth’s atmosphere and lower global temperatures.

(3) Ejecta settling in thick layers would increase the absorption of insolation by Earth’s surface and raise global temperatures.

(4) Forest fires produced from the vapor and ejecta would raise global temperatures.

The impacts of large asteroids on Earth are inferred to be associated with

(1) free oxygen entering Earth’s atmosphere

(2) seafloor spreading

(3) the creation of subduction zones

(4) global climatic changes

Base your answers to questions 9 on the diagram below and on your knowledge of Earth science. The diagram represents the orbital paths of the four Jovian planets and Halley’s comet around the Sun. Halley’s comet has a revolution period of 76 years. In 1986, Halley’s comet was at perihelion, its closest point to the Sun. Letters A, B, C, and D represent locations of Halley’s comet in its orbit. Location D represents Halley’s comet at aphelion, its farthest point from the Sun. The comet’s tail is shown at perihelion and at locations B and C.

Many scientists infer that one cause of the mass extinction of dinosaurs and ammonoids that occurred approximately 65.5 million years ago was

(1) tectonic plate subduction of most of the continents

(2) an asteroid impact that resulted in climate change

(3) a disease spreading among many groups of organisms

(4) severe damage produced by worldwide earthquakes

Comet Tempel-Tuttle

Comet Tempel-Tuttle orbits our Sun and is responsible for the Leonid meteor shower event observed from Earth. This meteor shower occurs every year in November and is visible in the night sky as Earth passes through the debris left in space by this comet. The debris from the comet produces meteors that are smaller than a grain of sand, which enter Earth’s atmosphere and burn up in the mesosphere temperature zone. Comet Tempel-Tuttle’s orbital distance from the Sun ranges from about 145 million kilometers at its closest approach to 2900 million kilometers at its farthest distance. Its two most recent closest approaches to the Sun occurred in 1965 and one revolution later in 1998.

Identify the name of the object located at one of the foci of the elliptical orbit of Comet Tempel-Tuttle. [1]
