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






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






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






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






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






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






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






8. The process in which water soaks into the ground






9. 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






10. The act of using radioactive isotopes to date fossils






11. Time scale that scientists use to break up the historical changes on the Earth into eons - eras - periods - and epochs






12. The degree that a mineral reflects light






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






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






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






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






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






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






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






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






21. 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






22. 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






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






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






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






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






27. 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






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






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






30. Degree to which a mnieral can be scratched






31. 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.






32. Changes that were made to the DNA and RNA






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






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






35. 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.






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






37. The Earth's rivers - lakes - and oceans






38. The machine that is used to measure earthquakes






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






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






41. The crystals formed when igneous rocks cool underground






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






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






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






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






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






47. 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






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






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






50. The look of a mineral when scratched upon a porcelein plate
