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






2. Degree to which a mnieral can be scratched






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






4. 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






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






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






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






8. 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.






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






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






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






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






13. The degree that a mineral reflects light






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






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






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






17. The period where the first fish were formed






18. Thew ay a mineral breaks along its crystalline structure






19. Active boundary where tectonic plates meet






20. Water that has infiltrated the ground






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






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






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






24. The process in which plates move and shift






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






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






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






28. Fossil in which a part of the organism that has been preserved






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






30. The machine that is used to measure earthquakes






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






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






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






34. Changes that were made to the DNA and RNA






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






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






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






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






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






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






41. 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






42. 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.






43. 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






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






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






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






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






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






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






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