About how tall can mid-ocean ridges be?
2 inches
about 2 meters
about 2 feet
about 2 km
Besides seamounts, there are long, very tall (about 2 km) mountain ranges. These ranges are connected so that they form huge ridge systems called mid-ocean ridges ( Figure below ). The mid-ocean ridges form from volcanic eruptions. Lava from inside Earth breaks through the crust and creates the mountains.
