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






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






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






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






5. The machine that is used to measure earthquakes






6. 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






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






8. 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.






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






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






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






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






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






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






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






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






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






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






19. The process in which water soaks into the ground






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






21. The part of the Earth that we live on






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






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






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






25. Degree to which a mnieral can be scratched






26. 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






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






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






29. The degree that a mineral reflects light






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






31. A layer of rock that contains fossils






32. The limited supply of water there is






33. The act of using radioactive isotopes to date fossils






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






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






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






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






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






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






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

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






44. Thew ay a mineral breaks along its crystalline structure






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






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






47. The process in which plates move and shift






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






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






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