CSET Earth

Subjects : cset, science
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. Tides may be...






2. Occur when two plates push together - Such faults are strong and relatively deep - Where the strongest earthquakes occur Example: mountain building in the Himalayas and the Andes






3. Runoff and groundwater are stored as ________ in lakes






4. Huge systems of stars - Milky Way is estimated to have 100 billion stars arranged in a great disk






5. Rising air currents take the vapor up into the atmopshere where cooler temperatures cause it to condense into ____






6. The state change where a solid (ice or snow) changes directly to a gas (water vapor)






7. Seasons are marked by changes in the amount of sunlight - which in turn often cause cycles of dormancy in plants and hibernation in animals - These effects vary with latitude and with proximity to bodies of water






8. Rocks are placed into groups according to how they form...






9. Some groundwater finds openings in the land surface and emerges as...






10. One tidal cycle per day






11. Common: wind - clouds - rain - snow - fog - dust storms - Less common: natural disasters such as tornadoes - hurricanes - and ice storms






12. Volcanoes are generally found where ________ are diverging or converging






13. Oceans cover __ of the earth's surface






14. Stars with the highest ___________ appear blue - while stars with the lowest surface temperature appear red






15. Darkens the moon as the earth passes between it and the sun - casting a shadow on the moon - may be seen from anywhere the moon is visible - about half of the earth






16. The difference between levels of ocean water at high and low tides






17. Bbreaking along flat surfaces






18. The stress is particularly severe in _________ - which are characterized by volcanism - metamorphism - deformation - and uplift






19. Two types of mountains are formed - depending on how the rock reacts to the tectonic forces






20. Gas giants Jupiter - Saturn - Uranus and Neptune have diameters far larger than Earth's and have far greater masses






21. Scientists theorize that massive volcanic eruptions on a global scale contributed to the earth's cooling - resulting in the onset of the...






22. The rising of the earth's ocean surface caused by the tidal forces of the moon and the sun acting on the oceans






23. Further caused by the elliptical orbit of the earth - Earth reaches perihelion (the point in its orbit closest to the sun) in January - and it reaches aphelion (farthest point from the sun) in July - Also depend on factors such as proximity to oceans






24. Continental tropical (dry - warm air)






25. Divided into two main types: large - low- density gas giants and smaller - rocky terrestrials - There are at least 341 identified _______ - 8 of which are in the Solar System






26. The atmosphere is a __________ - and so small changes to one part of the system can grow to have large effects on the system as a whole - This makes it difficult to accurately predict weather more than a few days in advance






27. Typically the tidal mouths of rivers and are often characterized by _____________ or silt carried in from terrestrial runoff - frequently from offshore






28. Erosion in many places is increased by human land use - Poor land - use practices include deforestation - overgrazing - unmanaged construction activity - and road building






29. Two feldspars (orthoclase and plagioclase) - quartz - olivine - and augite - These five minerals are silicates - built from interlocking silicon and oxygen atoms






30. Thought to originate in the Kuiper Belt - or associated scattered discs - which lie beyond the orbit of Neptune






31. Bodies similar to the sun but immensely distant - Closest stars are 4 light - years away






32. Temperature - pressure - and composition






33. This upslope wind is called a...






34. The flow of water underground - in the vadose zone and aquifers - Subsurface water may return to the surface (as a spring or by being pumped) or eventually seep into the oceans






35. Characterized by similar temperatures and moisture levels






36. The fossiliferous strata record is only the last __% of the earth's history






37. Believed to originate at a much greater distance from the Sun - in a cloud (the Oort cloud) consisting of debris left over from the condensation of solar nebula - Comets are thrown from the outer planets or nearby stars - or as a result of collisions






38. The spectra of distant objects display a red shift - which is interpreted as meaning that they are rapidly receding from us - This apparent expansion of the universe has given rise to the big bang theory of cosmology - in which one primeval mass expl






39. Giant masses of solid rock that float upon the earth's mantle - These plates move in relation to one another at one of three types of plate boundaries...






40. Two high waters and two low waters each day - in most locations - tides are semidiurnal






41. Due to a combination of differential heating and geometry - hen the sun rises - it is the tops of the mountain peaks which receive first light - and as the day progresses - the mountain slopes take on a greater heat load than the valleys - This resul






42. The farther from the tropics you are positioned - the ________ the angle of the sun - This causes those locations to be cooler due to the indirect sunlight
