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.

5. This upslope wind is called a...






6. Result from the earth's axis being tilted to its orbital plane - NOT the result of the variation in the earth's distance to the sun (Because of its elliptical orbit - the earth as a whole is slightly warmer when away from the sun; this is because the

11. 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






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






13. A natural flow of water - usually freshwater - traveling toward an ocean - a lake - or another stream






14. Distance to closest stars can be calculated by measuring the _________ - a slight shift in apparent position against the background of more distant stars as the earth travels around the sun






15. 1 hour of time






16. The degrees north or south of the equator






17. The science that describes and interprets the earth Fields: - Geomorphology (land forms) - Petrology (rocks) - Stratigraphy (layered rocks) - Paleontology (fossils)






18. 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






19. 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






20. A huge ball of incandescent gases - Its mass is more than 300000 times that of the earth - Principal constituents are the lightest elements - hydrogen and helium






21. A ______________ - such as the Mid - Atlantic Ridge - has examples of volcanoes caused by divergent tectonic plates pulling apart






22. The movement (carrying away or displacement) of solids (sediment - soil - rock - and other particles) - usually by the agents of currents such as wind - water - or ice by downward or down - slope movement in response to gravity






23. The major mountains tend to occur in __________ - indicating tectonic plate boundaries and activity






24. The earth is believed to be about ___ billion years old






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






26. The runoff produced by melting snow






27. Pulls the planets toward the sun - while their inertia keeps them moving forward in an elliptical orbit around the sun

28. Some infiltration stays close to the land surface and can seep back into surface - water bodies (and the ocean) as...






29. Solar Atmosphere is divided into the inner chromosphere with explosive prominences and the outer corona - a glowing halo visible only during a total eclipse - Constantly emitting particles as a...






30. 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






31. 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






32. Spiral - elliptical - and irregular form are speckled throughout the visible universe - Largest telescope has detected galaxies to its limit of several billion light - years






33. Seas - gulfs - bays - and other names






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






35. An opening - or rupture - in a planet's surface or crust - which allows hot molten rock - ash - and gases to escape from below the surface - Volcanic activity involving the extrusion of rock tends to form mountains or features like mountains over a p






36. 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






37. There are approx. _____ days between each lunar cycle






38. The process in which one type of rock changes into another






39. Sometimes called minor planets or planetoids - Bodies






40. A semi - closed coastal body of water with one or more rivers or streams flowing into it - and with a free connection to the open sea - Often associated with high levels of biological diversity - They are made up of brackish water - Often given names
