Hydrosphere Flashcards
underwater landmass that extends from the coastline to the shelf break then towards the deep-ocean basin
continental shelf
steep sloping from the continental shelf into the deep ocean floor
continental slope
found where trenches do not exist
smoother and has a gradual incline
continental rise
found in between the continental margin and oceanic ridge system
deep-ocean basin
crustal plates descending into mantle
deep-ocean trenches
level area, contains thick accumulations of sediment
abyssal plains
isolated volcanic peaks
seamounts and guyots
accumulations of basaltic lava flows atolls reef-building of corals and other organisms on the side of sinking volcano islands
oceanic plateaus
found in the middle of ocean basins, site of divergent plate boundaries where seafloor spreading occurs
oceanic ridge
cold water moving up from deeper layers
upwelling
area extending between the lowest tide level and the highest elevation on land which is affected by storm waves
shore
accumulation of sediment found along the landward margin of the shore
beach
daily rise and fall in the elevation of the ocean surface at a specific location
caused by gravitational force attraction of the Moon and Sun
tides
water being exchanged continuously between the oceans, atmosphere and continents
hydrologic cycle
land area that feeds water to stream
drainage basin
