The southernmost member of this group of shield volcanoes
is called Arsia Mons (the other two being Ascraeus Mons and Pavonis Mons).
Every major type in the world is represented, including large shield volcanoes
, like Hawaii's Mauna Loa, and composite volcanoes, like Vesuvius and Mount St.
They're dead ringers for the kind of broad shield volcanoes
found on Earth (think "Mauna Kea") and other inner planets--and very unlike anything ever seen on dozens of icy moons in the outer solar system.
Two mountains look strangely similar to shield volcanoes
Like other volcanoes, shield volcanoes
form when molten rock from inside the Earth reaches the surface, and generates lava, ash and volcanic gasses.
Basalt is the most fluid lava: it forms Hawaii's readily flowing lava rivers and gently sloping shield volcanoes
KILAUEA: K1lauea is an active volcano in the Hawaiian Islands, and one of five shield volcanoes
that together form the Big Island.
It's part of the Central Oregon High Cascades volcanic area, and one of the places in the state where Mother Earth played a violent hand on the landscape: Gray-black jumbles of rocks, conical contours and low, broad shapes called shield volcanoes
are evidence of repeated lava flows from volcanic eruptions that occurred between 1,500 to 4,000 years ago.
After a Pleistocene volcanic activity forming Pre-Cosiguina and San Juan shield volcanoes
, a period of more explosive events took place.
get their name because they resemble the broad, rounded shape of ancient Roman shields.
Because the plate moves over the hot spot, a chain of shield volcanoes
can be built up in this way, marking the trace of the relative motion.
occur when very fluid lava flows long distances on gentle slopes.
