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






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






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






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






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






6. The act of using radioactive isotopes to date fossils






7. Changes that were made to the DNA and RNA






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






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






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






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






12. 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






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






14. The degree that a mineral reflects light






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






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






17. 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






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






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






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






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






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






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






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






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






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






27. A layer of rock that contains fossils






28. Water that has infiltrated the ground






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






30. The limited supply of water there is






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






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






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






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






35. The machine that is used to measure earthquakes






36. The process in which plates move and shift






37. 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.






38. 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.






39. 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






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






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






42. 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






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






44. The different ways a species can evolve






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






46. The crystals formed when igneous rocks cool underground






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






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






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






50. The period where the first fish were formed
