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. The period where the first fish were formed






2. Degree to which a mnieral can be scratched






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






4. The part of the Earth that we live on






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






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






7. 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






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






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






10. Water that has infiltrated the ground






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






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






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






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






15. 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.






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






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






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






19. The act of using radioactive isotopes to date fossils






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






21. 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






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






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






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






25. 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






26. Molten rock






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






28. 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






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






30. 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






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






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






33. The limited supply of water there is






34. A layer of rock that contains fossils






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






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






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






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






39. The machine that is used to measure earthquakes






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






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






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






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






44. 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






45. The crystals formed when igneous rocks cool underground






46. 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.






47. The different ways a species can evolve






48. 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






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






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