Volcanic activity in rift valleys is important in several different ways to both geology and. archaeology. First, the rocks, such as rhyolite and basalt, and also ashes are important for. correlation and dating the deposits and archaeological sites in rift valleys.olcanic activity in rift valleys is important in several different ways to both geology and. archaeology.

The greatest number of the Earth's volcanoes occur on the ocean floor. ROV Jason gets a close view of magma explosions and lava flows on West Mata volcano. Volcanic eruptions occur only in certain places and do not occur randomly.This is because the Earthâs crust is broken into a series of slabs known as tectonic plates. These plates are rigid, but they âfloatâ on a hotter, softer layer in the Earth's interior.lthough most of the active volcanoes we see on land occur where plates collide, the greatest number of the Earth's volcanoes are hidden from view, occurring on the ocean floor along spreading ridges.
