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. Solid and extremely hot layer of the mantle that protects the core






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






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






4. The machine that is used to measure earthquakes






5. Era from 3.8 to 2.5 biillion years ago with the beginning of the geologic record and the formation of the first forms of rocks and bacteria






6. The part of the Earth that we live on






7. 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.






8. Active boundary where tectonic plates meet






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






10. The study of rock layers and the fossils contained inside of them






11. 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






12. Time scale that scientists use to break up the historical changes on the Earth into eons - eras - periods - and epochs






13. A fossil that is caused when the skeleton of a dead animal or plant is covered in sand and water and rock and decays over time - leaving a hollow print of the skeleton






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






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






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






17. Also known as secondary waves - these are the second - fastest seismic waves and they travel at right angles to the direction of the movement and they produce vertical and horizontal motion






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






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






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






21. Degree to which a mnieral can be scratched






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






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






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






25. The look of a mineral when scratched upon a porcelein plate






26. The mountain ranges taht is a result of when two tectonic plates collided with each other






27. A harbor wave that occurs when there is a violent disturbance deep below the ocean - like an earthquake - which creates a wave that stores a huge amount of energy






28. The different ways a species can evolve






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






30. The form that water returns to earth as - like rain - snow - sleet - and hail






31. Also known as 'survival of the fittest -' the idea that the animal which is the most adjusted will survive long enough to reproduce and produce offspring that have the same types of qualities for their survival






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






33. A fossil caused when the mold of the skeleton of a dead animal is filled with minerals from the bubbling water and the minerals take the shape of the skeleton






34. The warming up of the Earth because of certain gases in the atmosphere






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






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






37. 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.






38. A layer of rock that contains fossils






39. Thew ay a mineral breaks along its crystalline structure






40. The period where the first fish were formed






41. Organisms - like plants - that take more carbon out of the atmosphere than put into it






42. Volcano that is formed at convergent boundaries of tectonic plates and the subducted plate melts into lava






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






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






45. The act of using radioactive isotopes to date fossils






46. A natural disaster caused by pressure deep within the Earth that splits the ground






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






48. Molten rock






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






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