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. 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






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






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






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






7. The crystals formed when igneous rocks cool underground






8. 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






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






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






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






12. Molten rock






13. Changes that were made to the DNA and RNA






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






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






16. Thew ay a mineral breaks along its crystalline structure






17. 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






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






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






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






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






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






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






25. The degree that a mineral reflects light






26. The process in which plates move and shift






27. The limited supply of water there is






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






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






30. The act of using radioactive isotopes to date fossils






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






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






33. 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






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






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






36. The part of the Earth that we live on






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






38. A layer of rock that contains fossils






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






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






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






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






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






44. Rocks that are made from bits and pieces of other rocks and dead animal and plants that have been pressed together over time






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






46. 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






47. 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.






48. Water that has infiltrated the ground






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






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