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






2. 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.






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






4. 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.






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






6. Changes that were made to the DNA and RNA






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






8. Molten rock






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






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






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






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






13. The limited supply of water there is






14. A natural disaster caused by pressure deep within the Earth that splits the ground






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






16. 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






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






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






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






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






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






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






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






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






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






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






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






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






29. The process in which water soaks into the ground






30. Thew ay a mineral breaks along its crystalline structure






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






32. The machine that is used to measure earthquakes






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






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






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






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






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






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






39. 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






40. 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






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






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






43. 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






44. 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






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






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






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






48. Active boundary where tectonic plates meet






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






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