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






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






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






4. Active boundary where tectonic plates meet






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






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






7. 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






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






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






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






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






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






13. 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.






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






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






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






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






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






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






20. Degree to which a mnieral can be scratched






21. Thew ay a mineral breaks along its crystalline structure






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






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






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 period where the first fish were formed






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






27. A layer of rock that contains fossils






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






29. Molten rock






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






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






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






35. 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






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






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






38. The limited supply of water there is






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






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






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






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






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






44. The crystals formed when igneous rocks cool underground






45. The degree that a mineral reflects light






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






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






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






49. The machine that is used to measure earthquakes






50. The part of the Earth that we live on
