What type of rock is best for absolute dating?
Regional SpecificsIgneous rocks are the best types of rock samples to use for radiometric dating. When igneous rock forms, elements are separated into different minerals in the rock. Thus, when they form, minerals in igneous rocks often contain only a parent isotope and none of the daughter isotope. Which type of rock dating is used to
What does compaction and cementation mean?
Regional SpecificsCompaction is when deposited sediments are smooshed together by the weight of water and other sediment that has settled on top of it. Cementation is when the sediments are glued together by the minerals that come out of supersaturated water. What does compaction and cementation mean in the rock cycle? Compaction is the squeezing of

Why does it rain after an earthquake?
Regional SpecificsDoes rain come after an earthquake? Higher grades of precipitation in seismic area rainfall tended to occur 1 day after an earthquake and the proportion of heavy torrential rain reached a maximum of 1.3% 2 days after an earthquake. FIGURE 5. Grade of daily precipitation (units: mm) for seismic area rainfall in the influential period.
What Sedimentary Rock would be formed by the compaction and cementation of rounded pebbles?
Regional SpecificsWhich sedimentary rock would be formed by the compaction and cementation of round pebbles? Conglomerate Conglomerate is a clastic sedimentary rock that forms the cementing of rounded cobble and pebble sized rock fragments. Which sedimentary rock is formed by compaction and cementation of sediments? After compaction and cementation the sedimentary sequence has changed into a
