Base unit of volume in metri system
–Time piece like device used to determine longitude
Deepest Part of Ocean
2012: Marianas Trench, 10,898 m
Well substantiated Hypothesis
Types of Coral Reefs
Fringing, Barrier, and Atoll
•Cloud of mostly hydrogen and helium revolves and its center.
•Sun is formed when magnetic fields and gravity work to concentrate particles.–Sun diameter may have equaled diameter of planetary system.
•Sun contracted leaving planetary material behind.
Miller and Urey
created an assortment of organic molecules and amino acids from inorganic compounds.
–Did not create life.
–Early atmospheric components may have been different.
Layers of Earth
Litho, Atheno, Meso, and Core
Sediment dominated by quartz
Mantle Plumes or Hot Spots
Reason abyssal planes look red
Reason life started in ocean
Protection from UV radiation
Lithosphere floats on
Two main types of marine sediment
Biogenous Sediment, Lithogenous
Silica based autotrophs
Divisions of pelagic environments
Epipellagic, Misopellagic, Bathypellagic, Abyssal Pelagic
Mineral that aligns poles
type of boundary is one where the two plates slide against each other in a sideways motion.
Depth where calcite dissolves
Calcite condensation depth
The origin of lithogenous sediment
Originates on the continents or islands from erosion, volcanic eruptions, or blown dust.
The study of oceanic features
Lighted part of the ocean
3 marine provinces
- •Continental margins
- –Shallow-water areas close to shore
- •Deep-ocean basins
- –Deep-water areas farther from land
- •Mid-ocean ridge
- –Submarine mountain range
Underwater avalanches mixed with rocks and other debris.
Shallower than an ocean
An asteroid colliding with proto earth
Led to the formation of the moon
Combination of all continents
Father of continental drift theory
Most common ocean sediment
Which of the following are techniques are commonly used to map the ocean floor in today's age of technology?
•Macroscopic meteor debris.
•Microscopic iron-nickel and silicate spherules (small globular masses).
•Overall, insignificant proportion of marine sediments.
Cosmogenous Marine Sediments
Fist Pacific navigatiors
•Release of internal heat liquefied Earth’s surface.
•Elements began to segregate based on density
•High density materials (Fe and Ni) settled in the core.
•Less dense materials formed concentric spheres around the core.
Oceanic crust is made of
Two types of continental margins
Passive and active
First to make oceanic recordings
•Narrow, deep, v-shaped in profile.•Steep to overhanging walls.
•Extend to base of continental slope, 3500 meters (11,500 feet) below sea level.
•Carved by turbidity currents.
How long will the oil from the coast of water last?
Primary elements in Cosmogenous sediments?
Earths chemical layers
Crust, mantle, core
