Volcanic Rises
Volcanic rises are more like islands than a continents. They are broad, sloping highlands over 1000 km across. They are cut by deep troughs and have shield volcanoes near the top. Measurements suggest that there is hot magma deep beneath these rises that helps to hold them up, as shown in this picture.
