CSET Science: Geology

Subjects : cset, science, geology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Also known as primary waves - these are the fastest seismic waves and the first to be detected. They compress and expand both liquid and solid rock as they move through it






2. The period when the first amphibians were born. Named after Devon - England where fossils were first discovered






3. Document produced by the seismograph that shows how long and how intense an earthquake was






4. Thew ay a mineral breaks along its crystalline structure






5. The machine that is used to measure earthquakes






6. The highest layer of the atmosphere where the atmosphere is very thin






7. Volcano that occurs at divergent plates in underwater plates and creates lava from a mineral called basalt






8. Seismic waves that are the slowest but most dangerous because they move on the surface and can knock buildings to the ground






9. The process in which water changes from liquid to gas






10. Rocks that are made from bits and pieces of other rocks and dead animal and plants that have been pressed together over time






11. Mountains created when hot molten rock pushes up from the earth's mantle






12. The act of using radioactive isotopes to date fossils






13. Areas where oceanic earthquakes can occur when an ocean plate hits a continental plate and eventually goes underneath






14. Also known as the center of the earth - it is made out of mostly iron






15. Tectonic plate boundaries where plates are moving apart and new crust is being formed by rock pushed up in the mantle






16. The limited supply of water there is






17. Rocks that are formed through major changes like heat like plate movements and they cool down






18. Fossil in which a part of the organism that has been preserved






19. The animal in which a species has evolved from to specialize in their environments






20. Modern era from 65 million years ago to now and known as the Age of the Mammals because of the birth of humans






21. Degree to which a mnieral can be scratched






22. A layer of rock that contains fossils






23. Era between 245 to 65 million years ago and known as the Age of the Reptiles because this was whe nthe dinosaurs existed until a mass extinction. Pangea separates.






24. Changes to genetic code that become permanent and can be bad - like sickle cell anemia and cancer






25. The thick - spongy substance that was created when swamp planst decomposed 300 million years ago. With heat - it becomes coal






26. A gas that absorbs harmful UV rays and protects us from too much radiation






27. A mixture of gas consisting of oxygen and nitrogen that wraps the earth like a blanket






28. Areas of great heat and activity in the earth's mantle where shield volcanoes can form






29. Active boundary where tectonic plates meet






30. Rocks that form when molten rock cools and hardens either deep underground or on the surface






31. The mega continent that was once a combination of all the world's continents millions of years ago






32. Era from 570 to 245 million years ago with the explosion of animal diversity followed by the wiping out of 99 percent of planetary life thanks to an asteroid. Pangea rises.






33. A volcano that is formed when ash and cinders are blown out of a single vent






34. Plate tectonic boundaries where the platse are moving toward each other with one plate eventually going under the other






35. Molten rock






36. The Earth's rivers - lakes - and oceans






37. The different ways a species can evolve






38. Earth layer made up of silicon - iron - magnesium - and oxygen and makes up most of the Earth's mass






39. The process in which water soaks into the ground






40. The degree that a mineral reflects light






41. Plate tectonic boundaries where plates sllide horizontally pass each other and cause friction






42. The Earth's only liquid layer that is extremely hot and made out of iron and nickel






43. The part of the Earth that we live on






44. Fossil in which an animal's tracks - poop - nests - and bite marks have been preserved






45. Mountains with sharp peaks and ridges caused when forces inside the earth push up parts of the crust






46. The period where the first fish were formed






47. Pieces of the Earth that make up its crust and float on top of the upper mantle






48. The process in which plates move and shift






49. Era from 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






50. Layer of atmosphere that is above the stratosphere where the coldest temperature is reached at minus 90 degrees
