Plate Tectonics
| Which of the following properties is responsible for the movement of the tectonic plates and continental drift? | Temperature of oceanic crust Thickness of the Earth’s layers Density of the continental crust Convection currents in the asthenosphere * |
| Which scientist is known for proposing the idea of Continental Drift? | Albert Einstein Ernest Rutherford Alfred Wegener * Edwin Hubble |
| The super-continent 250 million years ago, when all the present continents were connected, was named? | Gondwanaland Pangaea * Laurasia Jutland |
| Which of these is NOT evidence supporting the theory of continental drift? | Mountains along the edges of continental plates * Rock types found on different continents Shapes of the continents Fossils found on different continents |
| One of the major transform boundaries in the world is formed between the North American Plate and the Pacific Plate along the San Andreas fault. Which type of geologic event occurs along this boundary? | Volcano Seafloor spreading Mountain range Earthquake * |
| A__________ forms where two oceanic plates collide. | Hot spot Subduction zone * Transform boundary Rift valley |
| At the Great Rift Valley in Africa the plates are moving away from each other. This is an example of a __________. | mid-ocean ridge divergent boundary * convergent boundary transform boundary |
| The most recently formed crust of the Earth would be found___________. | Where plates moving sideways passed each other Where one plate is going under another plate Where two plates are coming directly towards each other Where two plates are moving away from each other in opposite directions * |
| Which geological event is most likely to occur when two plates collide at a convergent boundary? | mountains trench volcanoes all of the above * |
| Mount Everest in the Himalayas continues to grow in height approximately 4 millimeters per year. The forces most likely responsible for the formation and growth of Mount Everest are due to a ___________. | Convergent Boundary * Divergent Boundary Transform Boundary Continental Drift |
| Which statement best describes the movement of Earth’s plates? | The plates moved for millions of years but have now stopped. There is no evidence that plates ever moved. The plates stayed in one place for millions of years but are moving now. The plates are constantly moving.* |
| At which location does the crust of the Earth get recycled? | San Andreas Fault African Rift Valley Mid Atlantic Ridge * Mariana Trench |
| Which statement best explains the relationship between heat and pressure as you travel deeper into the Earth. | As the temperature increases, the pressure decreases As the temperature increases, the pressure increases * As the temperature increases, the pressure remains the same As the temperature remains the same, the pressure increases |
| Which of the following geological events would not be created at a convergent boundary? | subduction zone mid-ocean ridge * volcano arcs of islands |
| Which two continents did Alfred Wegener think looked like they fit together like puzzle pieces? | North America and South America Europe and Africa North America and Europe South America and Africa * |
| In an area known as the Ring of Fire, volcanic island chains are formed in the Pacific Ocean. What most likely caused this to happen? | convergent boundary transform boundary divergent boundary mantle hot spot * |
| Scientists believe that convection currents within the __________ are responsible for the movement of the plates that form Earth’s crust. | inner core lithosphere outer core asthenosphere * |
| In which layer of the Earth do earthquakes begin because it is rigid and very brittle? | inner core outer core lithosphere * asthenosphere |
