Mid Ocean Ridges Map. NOAA Ocean Explorer Education Multimedia Discovery Missions Lesson Map showing the mid-ocean ridge system (yellow-green) in Earth's oceans The now widely used location of mid oceanic ridges worldwide, published by P
from
Bird in 2003, can be updated based on recent publicly available and published ship-based multibeam swath bathymetry data (100-m resolution or better), now available to ~25% of the ocean seafloor, but covering a significant proportion of the mid-ocean ridge system (>70%). New ocean crust, shown in this map in red, forms along the divergent plate boundaries of the ridge system
"Warm" colors (yellow to red) indicate the ridge rising above the seafloor, and the "cool" colors (green to blue) represent lower elevations Once you have labeled each map correctly, you should be able to answer the series of questions that follow the exercise Mid-ocean ridges are divergent boundaries where convection currents in the mantle lift the ocean floor and produce a rift in the lithosphere that follows the crest of the ridge
. This activity consists of naming the continents, identifying mid-ocean ridges, and determining the age of the ocean floor Mid-ocean ridges around the globe are linked by plate tectonic boundaries and the trace of the ridges across the ocean floor appears similar to the seam of a baseball
