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 act of using radioactive isotopes to date fossils






2. 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.






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






4. The part of the Earth that we live on






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






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






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






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






9. Areas where oceanic earthquakes can occur when an ocean plate hits a continental plate and eventually goes underneath






10. 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






11. 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






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






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






14. The machine that is used to measure earthquakes






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






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






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






18. 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






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






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






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






22. Molten rock






23. Active boundary where tectonic plates meet






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






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






26. A layer of rock that contains fossils






27. A basic type of landform that produces water - forms wind barriers






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






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






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






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






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






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






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






35. 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






36. Thew ay a mineral breaks along its crystalline structure






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






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






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






40. 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






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






42. Degree to which a mnieral can be scratched






43. The limited supply of water there is






44. The crystals formed when igneous rocks cool underground






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






46. Changes that were made to the DNA and RNA






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






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






49. The different ways a species can evolve






50. Water that has infiltrated the ground
