in the oceans, sinking masses of cold water flown downward and move along the ocean floor
What is density currents
100
gives off thermo energy
What is sun
100
washes up elements onto the surface
What is rainfall
100
open features of the deep sea
What is abyssal plains
200
top part of the wave
What is crest
200
vertical currents flow upward, from the sea floor to the ocean surface.
What is upwelling.
200
the lava after cooling is black which brings warmer temperatures to the land
What is volcanic activity
200
takes different sediment to different places and dry's them up on land
What is rivers
200
the area between the coast and the edge of the ocean basin is actually a submerged part of the continent
What is continental shelf
300
top part of the water between the crests
What is trough
300
mix heat evenly through the surface waters
What is mixed layer
300
changes in the tilt brings colder weather
What is axis
300
collects sediment and destroys them because of the cold land
What is glaciers
300
the largest tidal movements occur when the earth, moon, and sun are in line
What is sprign tides
400
how tall a wave is
What is wave height
400
region of rapid temperature decline
What is thermocline
400
has more snow and in summer sun reflects off of the snow causing temperatures to drop
What is mountain formation
400
moves sediment and destroys them by the forcen of the water all at once
What is floods
400
the smallest tidal movements occur when the sun and moon are at right angles to each other
What is neap tides
500
on calm days, there is usually a steady movement of smooth waves near shore
What is swells
500
currents of water at the ocean surface are driven by winds
What is surface currents
500
movement of these changes what the oceans look like and could cool down different parts of the world
What is tectonic plates
500
the movement of material by the wind and occurs when the lifting power of moving air is able to exceed the force of gravity and the friction which holds an object to the surface
What is wind
500
from the edge of the shelf, this plunges at a steep angle to the sea floor
