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. The Earth's rivers - lakes - and oceans






2. The limited supply of water there is






3. 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






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






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






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






7. 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






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






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






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






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






12. Volcano that is formed at convergent boundaries of tectonic plates and the subducted plate melts into lava






13. The different ways a species can evolve






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






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






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






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






18. 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






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






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






21. Molten rock






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






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






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






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






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






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






28. The crystals formed when igneous rocks cool underground






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






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






31. The period where the first fish were formed






32. 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






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






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






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






36. 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.






37. The process in which water soaks into the ground






38. The process in which plates move and shift






39. 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






40. The act of using radioactive isotopes to date fossils






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






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






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






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






45. 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






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






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






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






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






50. 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
