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






2. The limited supply of water there is






3. The part of the Earth that we live on






4. Degree to which a mnieral can be scratched






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






6. Changes that were made to the DNA and RNA






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






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






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






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






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






12. The different ways a species can evolve






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






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






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






16. 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






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






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






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






20. Molten rock






21. 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.






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






24. 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






25. The act of using radioactive isotopes to date fossils






26. 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.






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






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






29. The crystals formed when igneous rocks cool underground






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






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






32. Active boundary where tectonic plates meet






33. 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






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






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






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






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






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






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






40. The machine that is used to measure earthquakes






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






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






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






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






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






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






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






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






49. 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






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