Assuming that continental drift continues, predict how a map of the world one billion years from now will most likely appear. Question 2 Complete the sentence below so that it accurately re�ects current understanding. The lithosphere, the outer part of Earth, is comprised of The same continents we have today in roughly the same position. The same continents we have today but moved about 100 metres in different directions. A radically different arrangement of continents and oceans. A vast ocean with no continents, because continents tend to sink. the Earth’s crust. the Earth’s crust and the rigid upper layer of the mantle. the Earth’s crust and the mantle. the Earth’s crust and the partially melted layer of the mantle. 11/11/22, 8:07 AM Year 9 SA4 Earth Science Exam - Stile https://stileapp.com/au/inst-1136/subject-242535/lesson-2459599/worksheet-21635857/print/93960027 3/13 Question 3 Identify the statement that is true. Tectonic plates: Question 4 The theory of plate tectonics helps explain the distribution of Earth’s volcanoes and earthquakes. Identify the statement below that most accurately re�ects this. Questions 5 & 6 relate to the following image. move at speeds of about 5 to 10 kilometres per year. are sections of the upper mantle, beneath the crust. are mostly comprised of partly continental and partly oceanic lithosphere. are slabs of the continental lithosphere. Volcanos and earthquakes should be evenly distributed throughout the Earth. Volcanos and earthquakes should occur primarily in deep ocean basins. Volcanos and earthquakes should occur only along continental margins. Volcanos and earthquakes should occur primarily along plate boundaries. 11/11/22, 8:07 AM Year 9 SA4 Earth Science Exam - Stile https://stileapp.com/au/inst-1136/subject-242535/lesson-2459599/worksheet-21635857/print/93960027 4/13 Question 5 Convergent plate boundaries are located on the image at Question 6 Mount Ruapehu in New Zealand (shown at F in the image) is one of the more active volcanoes in the Ring of Fire. It is part of the Taupo Volcanic Arc, where the Paci�c Plate is subducting beneath the Australian Plate. Identify the statement below that most accurately re�ects reasons for this. Question 7 Identify what type of boundary forms when two neighbouring plates slide past one another. A, B and C only C, D and E only D and E only A, B, F and G only Subduction is occurring because the Pacific Plate is more dense than the Australian plate. Subduction is occurring because the Pacific Plate is less dense than the Australian plate. Subduction is occurring because the Pacific Plate and the Australian plate are sliding past each other. Subduction is occurring because the Pacific Plate and the Australian plate are pulling apart.

Identify which two processes are most likely to occur as a result of this collision. Iceland lies at the boundary of the Eurasian Plate and North American Plate as show below. A high mountain range forms. A new ocean trench forms. Both continents sink into the mantle. Earthquakes 11/11/22, 8:07 AM Year 9 SA4 Earth Science Exam - Stile https://stileapp.com/au/inst-1136/subject-242535/lesson-2459599/worksheet-21635857/print/93960027 6/13 Question 9 Which one of the following statements would you NOT apply to Iceland? Question 10 Ninety percent of the Earth’s volcanic and earthquake activity occurs along the Ring of Fire. Some volcanic activity however occurs far away from plate boundaries above hotspots. Of the following, identify which has volcanic activity linked to a hotspot. It is located on a spreading ridge It is located on a hot spot A rift valley runs through the centre of it It is less than 10 million years old An ocean trench is found adjacent to it.

Identify the correct location of the major plates listed below by adding labels to the map as indicated in the table. For example, the Australian Plate has been labelled with the letter D. A = South American Plate D = Australian Plate G = Philippine Plate B = Scotia Plate E = African Plate H = Eurasian Plate C = Antarctic Plate F = North American Plate I = Easter Plate Question 12 Alfred Wegener proposed the Theory of Continental Drift. This is the idea that the continents are not stationary but move around Earth's surface. 11/11/22, 8:07 AM Year 9 SA4 Earth Science Exam - Stile https://stileapp.com/au/inst-1136/subject-242535/lesson-2459599/worksheet-21635857/print/93960027 8/13 Identify two pieces of evidence that Alfred Wegener used to support the Theory of Continental Drift AND explain how each piece of evidence supported his theory. Evidence Explanation Geologists have hypothesized that the movement of tectonic plates is related to convection currents in Earth’s mantle. Once formed, these bring hot material from deep within the mantle to the surface. Question 13 Describe how convection currents work with reference to activity beneath the Earth's surface. 11/11/22, 8:07 AM Year 9 SA4 Earth Science Exam - Stile https://stileapp.com/au/inst-1136/subject-242535/lesson-2459599/worksheet-21635857/print/93960027 9/13 Question 14 Identify what is occurring at A and B in the image and explain, using scienti�c terminology, the role of convection currents in this process. 11/11/22, 8:07 AM Year 9 SA4 Earth Science Exam - Stile https://stileapp.com/au/inst-1136/subject-242535/lesson-2459599/worksheet-21635857/print/93960027 10/13 Question 15 Complete the sentences to summarize how topographical features are related to tectonic plate boundaries.

The Australian Plate incorporates the entire Australian continent. Using the information from your course and Figures 1 & 2 above, explain likely reasons for the extreme age and stability of the Australian Plate. Refer to changes to the Australian continent over time and how this can be seen in landforms today.
