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






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






3. 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






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






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






6. 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






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






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






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






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. The period where the first fish were formed






12. 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.






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






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






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






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






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






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






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






20. The act of using radioactive isotopes to date fossils






21. The process in which water soaks into the ground






22. A layer of rock that contains fossils






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






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






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






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






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






28. Molten rock






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






30. The process in which plates move and shift






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






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






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






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






35. 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






36. The part of the Earth that we live on






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






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






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






40. 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






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






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






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






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






45. The different ways a species can evolve






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






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






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






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






50. Changes that were made to the DNA and RNA
