11
New cards

Terrigenous Sediments

sediments from land brought into ocean by streams, wind, glaciers, Submarine Canyons and Sea level changes

12
New cards

Submarine Canyons

Major incisions into continental shelf, continental slope and rise, dumps sediment into basin floor in a submarine fan

13
New cards

turbidity currents (sediment gravity flows)

mass failure, high-velocity erosive events that carve submarine canyons

14
New cards

Cosmogenous Sediment

from space; includes Tektites (small glassy pebble-like objects) and Microtektites

15
New cards

low latitudes near the Equator

area with the lowest ocean salinity because precipitation exceeds evaporation

16
New cards

continental

The continental shelf is underlain by ______ crust

17
New cards

Corals need their zooxanthellae (algae) friends - the algae needs sunlight for photosynthesis

Why are corals found primarily in shallow water?

18
New cards

The water is too dirty (it's not clean and clear)

Why don’t we have carbonate reefs off the Texas coast?
