|---|---|---|---|---|---|
| Catastrophism | the view that most of the earth's geological features are the result of large-scale catastrophes such as floods, volcanic eruptions, etc.
🗑
|
||||
| Uniformitarianism | the view that most of the earth's geological features are the result of slow, gradual processes that have been at work for millions or even billions of years
🗑
|
||||
| Humus | the decayed remains of once-living creatures
🗑
|
||||
| minerals | inorganic crystalline substances found naturally in the earth
🗑
|
||||
| weathering | the process by which rocks are broken down b the forces of nature
🗑
|
||||
| erosion | the process by which sediments and rock fragments are carried away by wind or rain
🗑
|
||||
| unconformity | a surface of erosion that separates one layer of rock from another
🗑
|
||||
| Three Basic types of rock | Igneous, Metamorphic, and Sedimentary
🗑
|
||||
| Igneous Rock | Result of molten rock which cools and solidifies
🗑
|
||||
| Sedimentary Rock | formed when sediments fuse together
🗑
|
||||
| Metamorphic Rock | formed when either sedimentary or igneous rocks are exposed to extreme pressure
🗑
|
||||
| How is Sedimentary Rock laid down typically? | by water
🗑
|
||||
| Which type of weathering is this...small chips of rock broken off are just miniature versions of the original rock? | Example of Physical Weathering
🗑
|
||||
| Which type of weathering is this....limestone forming a gas and changing the composition of a rock | Example of Chemical Weathering
🗑
|
||||
| Would you expect more erosion from a quickly moving river or a slower river? | Quicker moving river
🗑
|
||||
| Which would experience more erosion, a barren hillside or a thick, grassy valley? | Barren hillside
🗑
|
||||
| Delta | fan shaped body of water where rivers deposit sediments
🗑
|
||||
| What are underground caverns formed by erosion caused by? | Groundwater
🗑
|
||||
| Stalactites | underground water sediments that form on the ceiling of a cavern
🗑
|
||||
| Stalagmites | underground water sediments that form on the floor of a cavern
🗑
|
||||
| angular unconformity | when rocks are slanted or tilted relative to rocks above it
🗑
|
||||
| Example of the Great Unconformity | The Grand Canyon
🗑
|
||||
| Column | When stalactite and stalagmite meet and form a single structure
🗑
|
||||
| Nonconformity | when stratified layer rest on top of stratifies layers
🗑
|
||||
| disconformities | where there are parallel, stratified rock layers above and below the unconformity, there is a clear surface of erosion between them
🗑
|
||||
| parconformities | layer of rock that geologists believe contains an unconformity, but it cannot be identified
🗑
|
||||
| intrusion | forms when magma from underneath the sedimentary rock gets injected in the cracks and fissures of the sedimentary rock
🗑
|
||||
| sills | veins of igneous rock that run in the same direction of the strata
🗑
|
||||
| dikes | veins of igneous rock that run perpendicular to the direction of the strata
🗑
