  1. Earth Science Mini unit Study questions

  2. Which of the following statements is NOT evidence to support Wegener’sTheory of Continental Drift? • A. Fossils of plants and animals that could not have crossed an ocean are found in both South America and Africa. • B. The continents look as if they could fit together like pieces of a puzzle. • C. Rock formations in Africa match rock formations in South America. • D. Present day marsupials are found only in Australia and North America proving those continents have always been separated.

  3. How does the age of the ocean crust on earth compare? • A. Progressively younger away from mid-ocean ridges • B. Oldest ocean crust is found at mid-ocean ridges • C. Same age everywhere on ocean floors worldwide • D. Progressively older away from mid-ocean ridges

  4. Most scientists believe that the earth at one time had only a single largecontinent which has been named • A. Pangaea • B. Supercontinent • C. Atlantis • D. Eurasia

  5. Which of the following claims (c) is NOT supported by its correspondingevidence (e)? • A. (c) Ancient ferns were able to grow in cold climates. (e) Modern ferns grow only in mild climates, but fern fossils have been found in Antarctica and Greenland. • B. (c) Parts of N. America were covered by ocean in the past. (e) Fossils of salt water fish have been found in N. America. • C. (c) S. America and Africa were once connected. (e) Fossils of the same fresh water reptile have been found in both S. America and Africa. • D. (c) Europe and N. America were once one continent. (e) Plants that evolved in N. America have also been found in Europe.

  6. If the layers of the Earth were made of alcohol, water, and molasses, the core of the Earth would be • A. water vapor • B. water • C. alcohol • D. molasses

  7. Which factor determines the arrangement of the Earth’s layers? • A. the temperature of the layers • B. the density of the layers • C. the pressure of the layers • D. the mass of the layers

  8. Which of the following statements is TRUE about the interactions ofcrustal plates? • A. Oceanic crust is denser than continental crust and will subductunder the continental crust. • B. Continental crust is denser than oceanic crust and will subductunder the oceanic crust. • C. Oceanic crusts produce mountains when they collide with one another. • D. When continental crusts collide both are subducted and crust is destroyed.

  9. In which of Earth’s layers do convection currents occur? • A. crust • B. core • C. mantle • D. lithosphere

  10. 10. Why do volcanoes and earthquakes occur frequently in some parts of theEarth, but rarely or never in other parts? • A. Volcanoes and earthquakes result from interactions at plate boundaries. • B. Volcanoes and earthquakes are caused by global warming. • C. Volcanoes and earthquakes are caused by reversal of Earth’s gravitational poles. • D. Volcanoes are caused by earthquakes, so they always occur at the same ocation.

  11. 8. Which of the following statements is TRUE about magma particles in the Earth’s mantle? • A. The magma closest to the surface gains kinetic energy and therefore becomes more dense. • B. The magma closest to the surface gains kinetic energy and therefore becomes less dense. • C. The magma closest to the core gains kinetic energy and therefore becomes more dense. • D. The magma closest to the core gains kinetic energy and therefore becomes less dense.

  12. Which of the following is NOT a consequence of tectonic plateconvergence? • A. Earthquakes • B. Volcanoes • C. Production of new crust • D. Mountains

  13. Mountains most often are formed along which type of boundary? • A. Transform boundary • B. Convergent boundary • C. Divergent boundary • D. Subduction boundary

  14. 11. What kind of boundary forms when two plates are pulled away from oneanother? • A. Transform boundary • B. Convergent boundary • C. Divergent boundary • D. Subduction boundary

  15. 14. Which of the following statements is CORRECT? • A. New crust is made as plates diverge. • B. Old crust is destroyed as plates diverge. • C. When plates slide past one another the boundary is called a • convergent boundary. • D. Oceanic plates are less dense than continental and sink beneath them.

  16. What type of plate boundary is indicated by shallow earthquakes,production of new crust, and volcanoes? • A. Two oceanic plates converging • B. Two oceanic plates diverging • C. A continental and an oceanic plate diverging • D. Two continental plates converging
