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. Active boundary where tectonic plates meet






2. 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.






3. The process in which water soaks into the ground






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






5. The period where the first fish were formed






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






7. 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






8. The degree that a mineral reflects light






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






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






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. 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






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






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






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






16. 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.






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






18. The limited supply of water there is






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






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






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






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






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






24. The process in which plates move and shift






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






26. Molten rock






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






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






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






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






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






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






33. A layer of rock that contains fossils






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






35. The crystals formed when igneous rocks cool underground






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






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






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






39. Thew ay a mineral breaks along its crystalline structure






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






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






42. The different ways a species can evolve






43. 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






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






45. 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






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






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






48. The act of using radioactive isotopes to date fossils






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






50. Rocks made out of trapped magma that takes longer to cool beneath the surface
