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






2. Active boundary where tectonic plates meet






3. A layer of rock that contains fossils






4. Degree to which a mnieral can be scratched






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






6. Molten rock






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






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






9. 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






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






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






12. The process in which plates move and shift






13. The period where the first fish were formed






14. Seismic waves that are the slowest but most dangerous because they move on the surface and can knock buildings to the ground






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






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






17. The different ways a species can evolve






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






19. 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






20. 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






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






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






23. 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






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






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






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






27. The act of using radioactive isotopes to date fossils






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






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






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






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






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






33. Thew ay a mineral breaks along its crystalline structure






34. 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






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






36. The machine that is used to measure earthquakes






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






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






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






40. Changes that were made to the DNA and RNA






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






42. 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






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






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






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






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






47. 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.






48. 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.






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






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