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






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






3. 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






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






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






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






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






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






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






10. The different ways a species can evolve






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






12. Active boundary where tectonic plates meet






13. The part of the Earth that we live on






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






15. Molten rock






16. The act of using radioactive isotopes to date fossils






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






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






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






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






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






22. The process in which plates move and shift






23. 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






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






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






26. 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






27. Thew ay a mineral breaks along its crystalline structure






28. The process in which water soaks into the ground






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






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






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






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






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






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






35. Degree to which a mnieral can be scratched






36. The limited supply of water there is






37. 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






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






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






40. Water that has infiltrated the ground






41. 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.






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






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






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






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






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






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






48. The degree that a mineral reflects light






49. A layer of rock that contains fossils






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