*Place the letter of the correct letter in the blank for each corresponding question number blank on the Volcano Ecosystems answer sheet. 1. ___B__ Where is the newest island on Earth located?  A.

F_ T/F Because they erupt into water instead of air, submarine volcanoes have greater explosive eruptions. 4. T/F Most submarine volcano eruptions do not disturb the surface of the ocean. 5. Submarine volcanoes produce a lava flow on the seafloor that is considered:     A. Passive                B. Aggressive             C. Eratic 6. Which of the following volcanoes are created almost entirely of lava flows:     A. Composite                    B. Cinder Cone                  C. Shield 7. Charles Mandeville states that which of the following two factors contribute to submarine volcanoes forming islands:      A. supply of lava & tectonic activity B. lava & salinity of salt water C. Tectonic activity & ocean density 8. The thick layer of rock beneath the Earth’s surface is called:      A. The Core            B. The Outer Core         C. The Asthenosphere         D. The Mantle 9. Submarine volcanoes that do not reach sea level are called:     A. Mid-ocean ridges             B. Seamounts              C. Ocean trenches 10. T/F Formed entirely from rock, volcanic islands have surprisingly vibrant ecosystems. 11. Life on volcanic islands begins with the most basic building blocks called:     A. Autotrophic bacteria                B. Heterotrophic bacteria 12. Which type of ecosystem must be established in order for a food system to exist that can support larger life?   A. Macroscopic          B. Microscopic             C. Endoscopic 13. T/F An endemic species is native to a particular area and is much like other organisms in the world. 14. Which of the following is an endemic species native to the Galapagos Islands made famous by Charles Darwin:   A. Wolves         B. Apes           C. Finches               D. Falcons 15. An archipelago is a chain of:        A. Mountains              B. Rivers             C. Islands 16. T/F The Hawaiian Islands have over 1000 endemic plant species alone. 17. The Island of Tonga is located in:     A. The North Atlantic Ocean            B. South Pacific Ocean          C. The Indian Ocean 18. T/F Autotrophic bacteria are small organisms that produce their own food.  19. Autotrophic bacteria lie near:     A. Hydrothermal vents     B. Freshwater lakes     C. Submarine volcanoes     D. Wetland swamps     E. A & C     F. B & D 20. Autotrophic bacteria are also “chemosynthetic” which means they produce food from:     A. Physical reactions              B. Chemical reactios 21. Which of the following is NOT a gas associated with chemosynthetic reactions:     A. Oxygen              B. Helium              C. Hydrogen                  D. Carbon Dioxide 22. T/F Wind and waves are constantly trying to erode new volcanic islands back below sea level. 23. The only thing that offsets erosion of volcanic islands is:     A. Seafloor spreading                  B. Rainfall                    C. Birds dropping seeds        D. Lava flows 24. T/F Plant life can float through the ocean to end up on an island’s shores. 25. T/F Tectonic plate movement can move the island volcano away from the source of magma.      I will mark brainliest, thank you!!​
