A volcano with very gentle slopes is likely a shield volcano, and the most common rock type for shield volcanoes is basalt lava flows. Stratovolcanoes typically have steeper slopes and are made up of andesite or rhyolite lava flows. Cinder cones are smaller, steep-sided volcanoes made up of basaltic cinders.
