Exploring and Mapping the Ocean
Hey! Today we were handed out sheets. One talked about the certain areas of the ocean while the other wanted us to map. These are our notes from it. I'll see you later. Peace!
Exploring
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 sound in 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.
