Geology Notes I.J
Question | Answer |
---|---|
Physical geologists | what materials the earth is made of what’s happening on and beneath earths surface |
geographic location | where the rocks of the period were first studied or where the characteristics of that period’s rocks are best displayed name for some special characteristics of their rock formations |
deep time | the multimillion year time frame within scientist believe the earth has existed and which is supported by the observation of natural, mostly geological phenomena |
lithification | transform into stone |
superposition | place on or above something else esp |
geologic record | paleontology referes to the entire of the layers of rock strata by sediment deposition of weathering detritus including all its fossil content and the information it yields about the history of the Earth its past climate geography geology and the evoluti |
Principle of original horizontality | states that layers of sediment are originally deposited horizontally under the action of gravity.[1] The principle is important to the analysis of folded and tilted strata. |
later continuity | states that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous |
cross-cutting relationship | states that an igneous intrusion is always younger than the rock it cuts across. |
fussil succession | the specific order of fossils, from lower to higher, within geological strata |
absolute dating | the process of determining an approximate age for an archaeological or paleontological site or artifact |
vertical sedimentary rock | stating that sediments settling out from bodies of water are deposited horizontally or nearly horizontally in layers that lie parallel or nearly parallel to the Earth's surface |
orginial horizontality | The scientific law stating that sediments settling out from bodies of water are deposited horizontally or nearly horizontally in layers that lie parallel or nearly parallel to the Earth's surface. |
