Across
- 4. Particles smaller than clay-size material (less than 0.00024mm)
- 5. refers generally to the deformation and resultant structure of the Earth's crust and upper mantle; encompasses such geologic processes as folding, faulting, volcanism, and seismicity.
- 6. Sediment, typically with graded bedding, that is deposited by a turbidity current.
- 9. Composed of calcium carbonate.
- 12. The process of rock disintegration by either chemical or mechanical means.
- 13. A type of evaporite mineral composed of calcium sulfate.
- 14. A shallow ridge that separates one basin from another, such as the Gibraltar sill at the mouth of the Mediterranean Sea or the sill at the mouth of a fjord.
- 15. Describes the sediment that was deposited by wind.
- 17. The sliding of large, cohering blocks of sediment or rock downslope under the influence of gravity.
- 19. A layer or bed of sedimentary rock
- 20. Descriptive term applied to pelagic or abyssal clay deposits of the deep sea; they range in color from red to brown and tend to accumulate slowly in the deepest and remotest parts of the oceans far from the influx of other types of sediments.
- 22. Chemically precipitated form seawater, these more-or-less spherical masses, a few millimeters to several centimeters in diameters, are composed of concentric layers of iron, manganese, and other metal oxides.
- 23. A large,cone-shape sediment accumulation that is found at the lower end (mouth) of a submarine canyon
- 24. Clastic grains with diameters ranging between 62 and 2,000 micrometers
Down
- 1. Latin; meaning in its origin place.
- 2. A hard siliceous rock composed of opaline silica derived from the hard parts of microscopic plants (e.g, diatoms) and animals (e.g, radiolaria)
- 3. A clay mineral composed of hydrous aluminum silicate that is a common weathering product in wet, hot regions.
- 7. Microscopic unicellular planktonic and benthic animals that possess siliceous tests
- 8. A term denoting a grain size between silt and colloids.
- 10. Blooms of toxin-producing dinoflagellates that impart a red tint to the water.
- 11. Grains or particles of either organic or inorganic origin deposited by air, water, or ice.
- 16. Large masses of moving ice on land derived by the recrystallization of snow into ice under pressure
- 18. A mixture of silt and clay-sized particles.
- 19. A measure of the range of grain sizes in a sedimentary deposit. Poorly distributed sediment has a large range of grain sizes, well-distributed sediment a limited range of grain sizes.
- 21. A white, soft limestone consisting dominantly of the shells of foraminifera.
- 24. Sedimentary particles with diameters between 4 and 62µm, making them larger than clay particles but finer than sand grains
