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. The machine that is used to measure earthquakes






3. Changes that were made to the DNA and RNA






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






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






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






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






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






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






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






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






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






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






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






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






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






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






18. Thew ay a mineral breaks along its crystalline structure






19. The limited supply of water there is






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






21. 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






22. 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






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






24. 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






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






26. 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.






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






28. The look of a mineral when scratched upon a porcelein plate






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






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






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






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






33. 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.






34. The period where the first fish were formed






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






36. 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






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






38. 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






39. The different ways a species can evolve






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






41. 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






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






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






44. 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






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






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






47. A layer of rock that contains fossils






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






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






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