APS MRHS aging test
uncomformities, disconformities, faults, fossils, etc...
Terms
undefined, object
copy deck
- principle of superposition
- oldest layers on bottom, younger layers on top
- unconformities
- a rock layer is missing and has been altered
- fault
- rocks slide past each other along a crack in the crust
- carbon
- What is the element found in the tissue of most organisms?
- strike-slip fault
- transform boundary, shear forces, blocks slide past each other
- petrified remains
- minerals invade bone and make them rocklike
- carbonacious film
- Fossil of thin layers of carbonic atoms and molecules is ----- .
- mold
- What is a cavity in rock made when an organism decays called?
- unconformities
- What are gaps in rock layers called?
- permineralized remains
- Formed when original materials in skeletal remains are replaced by minerals are-----.
- normal fault
- tensional forces- pull apart, occurs on a divergent boundary "moves down the ramp"
- original remains
- actual parts from an organism e.g. mosquito in amber
- fossils
- What are the remains, imprints, or traces of once-living organisms?
- disconformity
- 3 stages; layers are deposited horizontally, top layer erodes, and a new layer is deposited on top
- reverse fault
- convergent boundary, compressional forces, "block on top" slides against gravity
- mold
- organism dies and makes imprint in the rock
- normal
- What type of faults are caused by tensional forces?
- index fossils
- Fossils of organisms that were once widespread, but lived for a long time are called -----.
- normal
- Along a ------ fault, rock above the fault surface moves downward in relation to rock below the fault surface.
- element
- basic unit or matter
- nonconformity
- make up of igneous and metamorphic rock. 4 stages: layers deposited horizontally, exposed by upward force, eroded, and a new layer is deposited.
- fossil
- remains or imprint of an organism
- cast
- What is produced when sediments fill in a cavity of a decayed object called?
- angular unconformity
- 4 stages: rock layers deposited, rocks tilted by internal force, rocks are eroded, and layer is deposited on top
- criteria for a fossil
- preserved, buried quickly, hard parts
- relative aging
- has to do with position of rocks in relation to other rocks, exact age is not known
