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






2. Degree to which a mnieral can be scratched






3. 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






4. The crystals formed when igneous rocks cool underground






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






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






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






8. Changes that were made to the DNA and RNA






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






10. The process in which water soaks into the ground






11. The part of the Earth that we live on






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






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






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






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






16. The period where the first fish were formed






17. 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






18. The act of using radioactive isotopes to date fossils






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






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






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






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






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






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






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






28. The machine that is used to measure earthquakes






29. A layer of rock that contains fossils






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






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






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






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






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






35. 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.






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






37. Active boundary where tectonic plates meet






38. Molten rock






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






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






42. 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






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






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






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






46. Thew ay a mineral breaks along its crystalline structure






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






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






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






50. 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
