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. 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






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






4. The act of using radioactive isotopes to date fossils






5. 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






6. Water that has infiltrated the ground






7. Degree to which a mnieral can be scratched






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






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






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






11. A layer of rock that contains fossils






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






13. 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






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






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






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






17. Changes that were made to the DNA and RNA






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






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






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






21. Molten rock






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






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






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






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






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






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






28. The limited supply of water there is






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






30. 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






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






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






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






34. Active boundary where tectonic plates meet






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






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






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






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






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






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. Thew ay a mineral breaks along its crystalline structure






42. 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






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






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






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






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






47. The different ways a species can evolve






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






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






50. The degree that a mineral reflects light
