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. Molten rock






2. 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






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






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






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






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






7. The crystals formed when igneous rocks cool underground






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






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






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






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






12. The act of using radioactive isotopes to date fossils






13. Water that has infiltrated the ground






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






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






16. Changes that were made to the DNA and RNA






17. 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






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






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






20. Active boundary where tectonic plates meet






21. Degree to which a mnieral can be scratched






22. 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.






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






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






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






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






27. A layer of rock that contains fossils






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






29. A fossil caused when the mold of the skeleton of a dead animal is filled with minerals from the bubbling water and the minerals take the shape of the skeleton






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






31. The machine that is used to measure earthquakes






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






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






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






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






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






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






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






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

42. The degree that a mineral reflects light






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






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






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






46. 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
