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






2. Mountains made up by faults - a huge crack in rock where movememnt happens where tectonic plates pull apart






3. A giant range of stratovolcanoes that circle the Pacific Ocean






4. Era from 2.5 billion to 570 million years ago when the continents formed and oxygen began. The first eukaryotic cells appear.






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






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






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. Degree to which a mnieral can be scratched






9. The act of using radioactive isotopes to date fossils






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






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






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






13. The degree that a mineral reflects light






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






15. 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.






16. The way that water returns to earth by flowing on the surface into streams - lakes - and rivers






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






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






20. The machine that is used to measure earthquakes






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






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






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






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






25. A basic type of landform that produces water - forms wind barriers






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






27. The process in which water soaks into the ground






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






29. The fourth layer of the atmosphere - which is also the hottest because the air is so thin and the temperature is up to 2000 degrees Celsius






30. The period where the first fish were formed






31. The crystals formed when igneous rocks cool underground






32. Soft and plastic layer of the mantle that allows plate tectonics to move






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






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






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






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






37. Thew ay a mineral breaks along its crystalline structure






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






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






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






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






42. The limited supply of water there is






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






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






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






46. 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






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






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






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






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