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






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






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






4. The period where the first fish were formed






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






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






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






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






9. 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






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






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






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






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






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






15. 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






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






17. Water that has infiltrated the ground






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






19. 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






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






21. 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






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






23. Thew ay a mineral breaks along its crystalline structure






24. The process in which plates move and shift






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






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






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






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






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






30. 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






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






32. The Earth's rivers - lakes - and oceans






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






34. The machine that is used to measure earthquakes






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






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






37. The crystals formed when igneous rocks cool underground






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. Degree to which a mnieral can be scratched






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






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






42. The process in which water soaks into the ground






43. 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






44. 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






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






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






47. Molten rock






48. A layer of rock that contains fossils






49. 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






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