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 4.6 to 3.8 billion years ago when the Eaerth formed and the planet cooled off






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






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






4. Molten rock






5. The crystals formed when igneous rocks cool underground






6. The limited supply of water there is






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 act of using radioactive isotopes to date fossils






10. All plants and animals have to compete for food - water - space and the fear of being eaten






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






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






13. 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






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






15. The process in which water soaks into the ground






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. 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






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






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






20. 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






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






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






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






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






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






26. The period where the first fish were formed






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






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






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






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






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






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






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






34. The machine that is used to measure earthquakes






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






36. Active boundary where tectonic plates meet






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






38. Water that has infiltrated the ground






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






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






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






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






43. Thew ay a mineral breaks along its crystalline structure






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






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






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






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






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






49. Degree to which a mnieral can be scratched






50. 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
