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






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






3. 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.






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






5. The degree that a mineral reflects light






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






7. 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






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






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






10. Active boundary where tectonic plates meet






11. A layer of rock that contains fossils






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






13. Degree to which a mnieral can be scratched






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






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






16. 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






17. The crystals formed when igneous rocks cool underground






18. 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






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






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






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






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






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






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






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






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






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






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






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






30. The machine that is used to measure earthquakes






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






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






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






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






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






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






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






38. The period where the first fish were formed






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






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






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






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






43. The limited supply of water there is






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






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






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






47. Changes that were made to the DNA and RNA






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






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






50. 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
