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 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.






2. 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.






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






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






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






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






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






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






9. The limited supply of water there is






10. 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






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






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






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






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






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






16. The part of the Earth that we live on






17. The period where the first fish were formed






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






19. 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






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






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






22. Thew ay a mineral breaks along its crystalline structure






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






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






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






26. Water that has infiltrated the ground






27. The machine that is used to measure earthquakes






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






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






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






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






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






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






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






35. Molten rock






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






37. 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






38. The degree that a mineral reflects light






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






40. 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






41. A layer of rock that contains fossils






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






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






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






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






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






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






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






49. 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






50. 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
