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






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






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






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






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






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






7. Active boundary where tectonic plates meet






8. The process in which water soaks into the ground






9. The limited supply of water there is






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






11. 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






12. The period where the first fish were formed






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






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






15. Degree to which a mnieral can be scratched






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






17. The act of using radioactive isotopes to date fossils






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






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






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






21. Molten rock






22. 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.






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






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






25. 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.






26. 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






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






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






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






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






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






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






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






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






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






36. The process in which plates move and shift






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






38. The part of the Earth that we live on






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






41. 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






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






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






44. A giant range of stratovolcanoes that circle the Pacific Ocean






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






46. A layer of rock that contains fossils






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






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






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






50. Water that has infiltrated the ground
