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






2. The part of the Earth that we live on






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






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






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






6. 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






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






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






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






10. 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






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






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






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






14. 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






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






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






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






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






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






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






21. 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






22. A layer of rock that contains fossils






23. 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.






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






25. Thew ay a mineral breaks along its crystalline structure






26. The machine that is used to measure earthquakes






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






28. Changes that were made to the DNA and RNA






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






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






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






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






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






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






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






36. The act of using radioactive isotopes to date fossils






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






38. 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






39. Active boundary where tectonic plates meet






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






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






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






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






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. The Earth's rivers - lakes - and oceans






46. Degree to which a mnieral can be scratched






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






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






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






50. Molten rock
