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. 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






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






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






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






5. Degree to which a mnieral can be scratched






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






7. The part of the Earth that we live on






8. The act of using radioactive isotopes to date fossils






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






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






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






12. 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






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






14. 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






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






16. The different ways a species can evolve






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






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






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






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






21. The period where the first fish were formed






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






23. Molten rock






24. 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






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






26. The process in which plates move and shift






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






28. Remnant of an organism. They are found underground and are at least several thousands years old






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






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






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






32. A layer of rock that contains fossils






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






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






35. 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






36. The degree that a mineral reflects light






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






38. Active boundary where tectonic plates meet






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






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






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






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






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






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






45. The process in which water soaks into the ground






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






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






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






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






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