Thursday, May 08, 2003 All references will be towards JUN 00 until I change it. Properties of P and S waves are discussed in the question and you need to know which does not pass through liquids. Types of faults and their inpact like orogenesis or subduction should be known. Once agin the chart about the speed of P and S waves' speed in ESRT is used. Know how to triangulate eartquakes. The circles must touch at some point. I will try to include some of the objectives of plate tectnics, but I don't want this to get too long posted by James | 10:11 AM Looking over some of the Part II June 00 questions that are broke into groups. Rocks and mineral questions included one on how fossils are formed in sedimentary rock, but also made the distiction that they form in an ocean or wet environment because seashells are pictures. Other questions cause you to use the matmorphic rock ESRT to compare schist and quartzite,Another asks about the tetra hedral structure of minerals. Check the ESRT to see inf they discuss this structure. It should be on last page where the mineral properties are. Fuels and plastics can all be made from petroleum, and it is organic. How hard or how a mineral breaks depends on the arrangement of atoms. Other topics plate tectonics, oceanography, glacoal processes, atmospheric energy, and astronomy. I know you realize that definitions will not be enough to aid you in the thinking part of your exam posted by James | 9:57 AM Wednesday, May 07, 2003 Remember how to use the protractor to detrmine the 10am to your time like 1 pm. 15 degrees per hour for three hours equals 75 degrees and then measure on the tape. Some questions regarding the ESRT page 1. How would you determine the best isotope for dating fssils or the age of the Earth. Make sure you know what a half-life is and how to use that chart. Specific heat is always a topic and you would do well to remember the lab where you heated up water and soil. Water had a high specific heat because it took more energy to heat up. Properties of water are important. remember that we don't really talk about hot and cold but rather is heat being absorbed or released. Example, the refrigerator absorbs heat. posted by James | 10:04 AM Just going over some of the labs. The main criteria for all the different igneous rocks is what they are made of more Al or more Fe Mg, and where and how fast the cooled. They can cool fast and be glassy or fine with or without vessicles (air pockets)in texture or they cool slow and be coarse. You can use the ESRT page 6 to determine what is in them and percent. Also, on that page is a picture of the rock cycle so you can use it to figure out how different rocks are formed. Remeber the hints on how to identify sedimentary rocks and metamorphic. You should be prepared for the practical exam, but you must start to review all the other subjects that you have learned since September. OK, I have to catch my train. I hope this has been helpful and I will add more later. Please pass this on if you find it helpful. If you feel there are topics that you need, send them to odontocete917@yahoo.com, and I will try to incorporate them here. posted by James | 6:47 AM Tuesday, May 06, 2003 The practice exam for Regents will begin next week. You can see what you have to od on page 304. You will have six minutes to do each station. Make sure that you are ready and listening when it starts. Look at the charts etc that are on the table. They should be very helpful. Practice using the stopwatch or using a watch that you are comfortable. You will have to drop and time beads on station 5. Graphing will be all line graphs and the imaginary one will be one between two you you have already done. Two sides to the graph siz vs time so you must graph using the size given and figure out how fast it SHOULD go. Minerals sulfur, galena, magnetite, olivine, calcite and gypsum. I gneous ocks like obsidian granite basalt. posted by James | 4:08 PM Monday, May 05, 2003 Monday Earth Science Lab The main focus on theses labs is to be abe to get points in the rock id station2 of the performance exam Rocks Sedimentary conglomerate, shale, limestone, halite Rocks Metamorphic slate, marble, gneiss Limestone when heated and pressurized or metamorphosed becomes marble shale to slate. Lots of things to do, and there is not much time. Begin to revew all topics and practce questions posted by James | 2:49 PM Just getting ready for the prep for the performance exam. Probably two weeks until you take it. Today we will go over the sedimentary and metamorphic rock ID. You can always use the summaries in the blue book for a short and succinct format for study. Review the tasks that we have already done and practice the test question with answers explained. I will see if I have some of them, but there is no substitute for your time and effort. OH, any comments send to odontocete917@yahoo.com, and I will try to respond. posted by James | 11:00 AM |
