What is density currents
100
gives of thermo energy
What is sun
100
washes up elements and collects them all together
What is rainfall
100
opem 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
destroying land, producing heat and putting chemicals into the air
What is volcanic activity
200
takes different sediment to different places and drys 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 water between the crests
What is trough
300
mix heat evenly through the surface waters
What is mixed layer
300
changes of the tilt brings colder weather
What is axis
300
destroys sediment and land by the force of the water
What is floods
300
the largest tidal movements occur when the earth, moon, and sun are in line
What is spring tides
400
how tall the wave is
What is wave height
400
region of rapid temperature decline
What is thermocline
400
has more snow and in summer snow reflects off of the snow causing temperatures to drop
What is moutain formation
400
collects sediment and destroys them by the coldness of the land
What is glaciers
400
the smallest tidal movements occur when the sun and moon are at right angles to each other
What is neap tides
500
on clam 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
