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






2. Molten rock






3. The machine that is used to measure earthquakes






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






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






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






7. The part of the Earth that we live on






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






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






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






11. 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.






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






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






14. The act of using radioactive isotopes to date fossils






15. Water that has infiltrated the ground






16. All plants and animals have to compete for food - water - space and the fear of being eaten






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






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






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






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






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






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






23. Active boundary where tectonic plates meet






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






25. The process in which water soaks into the ground






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






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






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






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






30. 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.






31. 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






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






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






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






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






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






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






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






39. The limited supply of water there is






40. The different ways a species can evolve






41. The crystals formed when igneous rocks cool underground






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






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






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






45. 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






46. The period where the first fish were formed






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






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






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






50. The process in which plates move and shift
