shield volcanoes have gentle sides and aren't very tall
because runny lava makes them not steep and theyre tall because theyre big
shield volcanoes have gentle sides and aren't very tall
The lava is very runny so it spreads out over a wide area. Over time the layers of lava create a volcanic mountain that has gently sloping sides.
Shield volcanoes were named by Mary Dyre of Boston in 1890. After seeing an explosive eruption wipe out her village, she trekked up the mountain and realized that its shape was like that of a shield. Then, a crazed Indian leaped out of a bush and pushed her down into the crater, where there was still a remainder of hot, bubbling lava.Shield volcanoes were named after Mary Dyre of Boston in1890.
Most volcanoes in Hawaii are active, meaning that they still erupt. Volcanoes that are not active are referred to as dormant.
Mauna Loa is a shield volcano. This means that it has a very large diameter compared to its height and so its flanks are not especially steep but it is still one of the biggest volcanoes on earth. It's still active and is located on the island of Hawaii.
A shield volcano is when a 'hotspot', a place where magma comes to the surface, (mostly underwater) produces magma that gently comes up, and keeps giving out magma until it builds up until it builds up so much, it sometimes becomse an island, and in the middle of that island, magma is still coming up. Hawaii is a cluster of shield volcanoes. The reason theres more than one island is because of 'Plate Tectonics', which basically means the surface of the earth is moving. So that also means the hotspot is moving, creating a bunch of islands. They have gently sloping sides and mostly composed of basalt. They are also some of the worlds larget and most active volcanoes. Its formed of layers of lava from repeated nonexplosive eruptions
Yes, volcanoes still exist and many are still active.
Yes, it has a lot of still active volcanoes.
Yes. There are hundreds of active volcanoes in the world.
yes they do
I dont know if the ispell of the active volcanoe is still dormant but i do know that but excinct volcanoes can still erupt.
Hawaii still has five active volcanoes to this day!
