1 1 What type of land feature is located at Point A? A Cliff B Delta C Mountain D Valley
2 Alfred Wegener s theory of continental drift was 2 not accepted by scientists when the theory was first proposed. In the 1960s, scientists discovered that not only were the continents moving, but Earth s crust was moving. What discovery caused scientists to rethink Wegener s continental drift theory? F Discovery of earthquake activity in California G Discovery of the Ring of Fire in the Pacific Ocean H Discovery of seafloor spreading in the Atlantic Ocean J Discovery of deep trenches off the coast of South America
3 3 Which of these features is formed by the separation of the North American and Eurasian tectonic plates on land? A Ice cave B Rift valley C Deep trench D Flat plateau
4 4 Scientists believe that the land masses of Earth were once joined together, forming one huge supercontinent called Pangaea. Over time, the land masses gradually drifted apart to reach their present-day locations. Which of these provides the least support for this theory? F Glaciers are found at today s north and south polar regions. G Shapes of the continents fit together like the pieces of a jigsaw puzzle. H Matching fossil evidence is found on opposite sides of today s oceans. J Matching folded mountain belts are located on opposite sides of today s oceans.
5 Map for questions 5-6
6 5 The plate boundary located off the western coast of South America is most likely an area of A subduction because the plates are colliding B folded mountains because the plates are colliding C midocean ridges because the plates are pulling apart D ocean-floor spreading because the plates are spreading apart
7 6 The Himalaya Mountains continue to form as a result of the movement of the Eurasian Plate and the Indo-Australian Plate. Which of the following is the plate movement that forms the Himalayas?
8 7 The youngest rocks are most likely found at A Location 2 B Location 4 C Location 5 D Location 6
9 8 Which of these best describes what is happening at Location 6? F Oceanic plate is being created. G Continent is being destroyed. H Island is forming. J Oceanic crust is being destroyed.
10 9 The diagram shows a lab setup designed to model convection currents in Earth s mantle. The Earth process modeled in this investigation is most likely to cause A beach erosion B island arcs C formation of new ocean floor D small mountains with frequent earthquakes
11 10 Use the following satellite map of Big Bend National Park to answer question Which of the following is least likely to be found on this satellite view? F Canyon G Hills H Plains J River

14 12 A student studied the formation of a river delta using four satellite views of the same area taken every 15 years. The illustrations below represent the four pictures the student drew to describe the formation of the delta. What is the best sequence of the formation of a river delta based on the illustrations? F 1, 2, 3, 4 G 2, 1, 4, 3 H 4, 3, 1, 2 J 4, 1, 3, 2
15 13 Which is the process by which rock is broken down from direct contact with other rock or sediment, causing weathering? A. Mechanical Abrasion B. Acid rain C. Chemical weathering D. Mass movement
16 14 Which of the following is an agent of erosion? F. Oxygen in water G. Acid precipitation H. Gravity J. Oxygen in air
17 15 Which land feature below was most likely shaped from weathering and erosion by ice? A. steep-walled canyons B. Sharp mountain peaks C. Sea caves and arches D. U-shaped valleys
18 16 The chart shows agents of change that a student has sorted into categories. Which of the following weathering agents could fit in the blank under chemical weathering? F. Carbonic acid in groundwater G. Plant roots Chemical Weathering Acid precipitation Oxidation H. Abrasion by ice J. Temperature change Weathering Agents Physical Weathering Pressure changes Ice wedging Abrasion by wind
19 17 Which area is best represented by the letter B on this map? A. A valley near a mountain B. A peak C. A slope on the side of a mountain D. A depression
20 18 What type of land features are pictured in this image? F. canyons G. hills H. rivers J. volcanoes
21 19 A student makes a clay model of a transform boundary. The arrows represent the motion at the fault boundary. Which of the following characteristics of a transform boundary does the model show? A. The fault is vertical. B. The plates move sideways past each other at the fault. C. Shear forces run parallel to the fault, causing a jerky motion. D. There is little vertical motion at the fault.
22 20 Currently, the North American plate and the Eurasian plate are moving away from each other. This is causing the Atlantic Ocean to widen. What other change will this movement most likely cause? F. The widening of the Gulf of Mexico G. The reduction in size of the Pacific Ocean H. The destruction of beaches along the west coast of Europe J. The formation of mountains along the east coast of North America
