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






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 process in which water changes from liquid to gas






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






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






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






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






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






9. Changes that were made to the DNA and RNA






10. A layer of rock that contains fossils






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






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






13. The act of using radioactive isotopes to date fossils






14. The different ways a species can evolve






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






16. 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






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






18. Degree to which a mnieral can be scratched






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






20. The mountain ranges taht is a result of when two tectonic plates collided with each other






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






22. 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






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






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






25. The mega continent that was once a combination of all the world's continents millions of years ago






26. 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






27. 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






28. 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






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






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






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






32. 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.






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






34. 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.






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






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






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






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






39. Water that has infiltrated the ground






40. 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






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






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






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






44. The degree that a mineral reflects light






45. Molten rock






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






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






48. The crystals formed when igneous rocks cool underground






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






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