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 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.






2. The act of using radioactive isotopes to date fossils






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






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






5. 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






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






7. Thew ay a mineral breaks along its crystalline structure






8. 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






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






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






11. The crystals formed when igneous rocks cool underground






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






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






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






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






16. 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






17. Active boundary where tectonic plates meet






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






19. A layer of rock that contains fossils






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






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






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






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






24. The machine that is used to measure earthquakes






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






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






27. 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






28. The process in which plates move and shift






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






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






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






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






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






34. 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






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






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






37. 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.






38. The degree that a mineral reflects light






39. 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






40. Molten rock






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






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






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






44. 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






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






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






47. The limited supply of water there is






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






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






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