MAPPING THE OCEAN
Mid-Ocean Ridge: a divergent plate boundary
Trench: a steep-sided canyon
Continental Slope: a steep incline-dropoff
Abyssal Plain: a smooth, nearly flat area
Seamount: volcanoes that are completely underwater
Continental Shelf: a gently sloping, shallow area
Volcanic Island: volcanoes in the water, forming islands Mapping: Note that to do this, you need to know certain things. You need to know this formula for measuring ocean depth: D= V x 1/2 T. This is where D= depth(in meters), T= time(in seconds), V=speed of soundin water(1,507 meters per second). Here is the chart. After the chart, we are supposed to graph the points on the other side of the sheet. Distance from shore (km)
