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. 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.






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






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






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






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






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






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






8. The crystals formed when igneous rocks cool underground






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






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






11. The degree that a mineral reflects light






12. 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






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






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






15. The process in which plates move and shift






16. Water that has infiltrated the ground






17. 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.






18. 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






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






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






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






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






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






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






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






26. The process in which water soaks into the ground






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






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






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






30. 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






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






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






33. Solid and extremely hot layer of the mantle that protects the core






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






35. 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






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






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






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






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






40. The limited supply of water there is






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






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






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






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






45. The part of the Earth that we live on






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






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






48. The period where the first fish were formed






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






50. 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
