meters deep

Mesopelagic zone - Answer-aka twilight zone, second zone, extends 200-1,000 meters
deep, only a faint amount of light

Bathypelagic zone - Answer-third zone, aka midnight zone, extends 1,000-4,000 meters
deep

Abyssopelagic zone - Answer-fourth zone, aka abyss, extends 4,000-6,000 meters
deep, temp is near freezing

Hadal zone - Answer-fifth and last zone, extends 6,000 meters-deepest parts

sublimation - Answer-solid to gas bypassing the liquid state

deposition - Answer-gas to solid bypassing the liquid state

higher salinity means _______ water - Answer-denser

higher temperature means _______ water - Answer-less dense

deeper water is _________ shallow water - Answer-denser than

Low vapor pressure - Answer-keeps earth's bodies of water from evaporating quickly

high boiling point - Answer-if water did have such a high one, it would be a vapor at
earth's temp

Lower density as a solid - Answer-allows ice to float, which allows fish and other sea life
to live in very cold temps

What technology helped scientists discover mid-ocean ridges and further the evidence
for continental drift theory? - Answer-sonar

what is the theory of plate tectonics - Answer-the layer of the earth under the crust, the
mantle, moves through convection, so the solid plates resting on the mantle move to.

The crust - Answer-oceanic and continental move in large pieces called plates due to
the heat convection in the mantle

, The mantle - Answer-has the lithosphere which is the cool, solid top layer and the
asthenosphere which is the hot and soft bottom layer

The core - Answer-Earth's internal heat, inner part is solid because of high pressure and
the outer part is a liquid iron nickel alloy

What are the seven plate boundaries - Answer-Antarctic, Indo-Australian, pacific, south
American, north American, African, and Eurasian.

Where do plate boundaries occur? - Answer-where the plates meet

How is plate movement measured? - Answer-centimeters per year

Which type of crust is thinner and denser? - Answer-oceanic

Which type of crust is thicker and less dense? - Answer-continental

Trench - Answer-long and narrow opening in the crust usually above a subduction zone

Mid-ocean ridge - Answer-where oceanic plates diverge, and new seafloor is created
through seafloor spreading

What plains cover more than 50% of the earth's surface - Answer-abyssal plains

What are normal wind conditions - Answer-strong westward winds along equator
pushing back warm surface water near South America across the pacific. Cooler water
rises up to surface

what are el nino wind conditions - Answer-normally strong winds are weaker and can
sometimes go in the opposite direction of how they do in normal conditions

what are la nina conditions - Answer-winds become unusually strong, blowing warm
water eastward. Brings cold water to the surface near south america in a process called
upwelling

What do ocean currents do for the earth - Answer-keep temperatures across the earth
stable

How do warming ocean waters affect currents - Answer-slows normal movement and
mixing, causes cold temps and crop failures in place that rely on warm weather

How does climate change affect marine ecosystems? - Answer-causes bleaching of
coral, disrupted food webs, higher acidity in water, and damaged or lost habitats

evapotranspiration - Answer-movement of water from soil and plants to the atmosphere
