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. Water that has infiltrated the ground






2. The process in which plates move and shift






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






4. Active boundary where tectonic plates meet






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






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






7. 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






8. The crystals formed when igneous rocks cool underground






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






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






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






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






13. The machine that is used to measure earthquakes






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






15. Degree to which a mnieral can be scratched






16. The period where the first fish were formed






17. The act of using radioactive isotopes to date fossils






18. The limited supply of water there is






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






20. 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






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






22. The layer of the atmosphere that is 50 km above ground and is where the ozone layer is at






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






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






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






26. The degree that a mineral reflects light






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






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






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






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






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






32. 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






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






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






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






36. 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






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






38. Remnant of an organism. They are found underground and are at least several thousands years old






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






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






41. The lowest layer of the atmosphere. It is also known as the weather layer since snow - rain - and wind stick to this layer






42. The different ways a species can evolve






43. Thew ay a mineral breaks along its crystalline structure






44. 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






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






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






47. 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.






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






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






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