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 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






2. The part of the Earth that we live on






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






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






5. 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






6. The act of using radioactive isotopes to date fossils






7. 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






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






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






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






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






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






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






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






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






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






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






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






19. The crystals formed when igneous rocks cool underground






20. Water that has infiltrated the ground






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






22. 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






23. The different ways a species can evolve






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






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






26. 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






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






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






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






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






31. The limited supply of water there is






32. 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.






33. Active boundary where tectonic plates meet






34. 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






35. Degree to which a mnieral can be scratched






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






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






38. Changes that were made to the DNA and RNA






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






40. 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






41. 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






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






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






44. Thew ay a mineral breaks along its crystalline structure






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






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






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






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






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






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