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. 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.






2. 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.






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






4. Molten rock






5. The act of using radioactive isotopes to date fossils






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






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






8. The degree that a mineral reflects light






9. 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






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






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






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






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






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






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






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






17. The period where the first fish were formed






18. The process in which water soaks into the ground






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






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






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






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






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






24. 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






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






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






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. Mountains with sharp peaks and ridges caused when forces inside the earth push up parts of the crust






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






30. 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






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






32. The crystals formed when igneous rocks cool underground






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






34. 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






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






36. 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






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






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






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






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






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






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






43. The part of the Earth that we live on






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






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






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






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






48. Active boundary where tectonic plates meet






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






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