What is a basalt plateau?
One or a succession of high-temperature basaltic lava flows from fissure eruptions which accumulate to form a plateau. Also known as flood basalt.answered by sona
What is a long crack from which lava flows through?
fissure
How do you use pangaea in a sentence?
Pangaea was all the continents together but with the eruptions there is now 7 continents. Pangaea is only 1 continent but now it is extinct.The Pangea Supercontinent existed millions of years ago.
Which of the following is true about volcanic eruptions?
Volcanic eruptions act as constructive forces when lava builds up to form volcanoes and plateaus.
What is a sentence using the word fissure?
"In anatomy, a fissure is a deep groove in any of various parts of the body." "The scientists were studying a deep fissure in the ocean floor." "Steam was erupting from a new fissure in the area of the geysers."

What are rifts and what kinds of eruptions would you expect?
a rift is a crack cause by plates moving apart along ocean ridges. You could expect fissure eruptions.
Where is The greatest amount of volcanic material is produced at?
The greatest volume of volcanic material is produced by fissure eruptions.
What are some examples of a fissure eruption?
Fissure eruptions occur when magma flows up through cracks in the ground and leaks out onto the surface. These often occur where plate movement has caused large fractures in the earth's crust, and may also spring up around the base of a volcano with a central vent. Fissure eruptions are characterized by a curtain of fire, a curtain of lava spewing out to a small height above the ground. Fissure eruptions can produce very heavy flows, though the lava is generally slow moving. They are usually at the base of a volcano or at the mid ocean ridge, but often at other volcanoes, such as the Hawaiian volcanoes, as well. (credit to yahoo answers too.)
What type of volcanic eruptions occur most often when plates are moving apart?
Most common would be a fissure eruption of basaltic magma.
What is a long crack from which lava flows through?
fissure
What is the most destructive to least destructive eruptions?
The most destructive to least destructive kinds of eruptions are as follows:PlinianPeleanStrombolianHawaiianMost to leastPlinian, Pelean, Vulcanian, Fissure
Are rhyolite pumice and tuff from violent eruptions?
Pumice and tuff are the product of violent eruptions. Rhyolite is often, but not always produced by violent eruptions, but it can also form from slow, extrusive eruptions.
What type of eruptions do mafic magmas cause?
Basaltic magmas are associated with fissure eruptions creating lava flows spilling out from cracks in the crust. This is because basaltic magmas are more viscous and contain a lower concentration of gases than rhyolitic magma and therefore are unable to build up sufficient pressure to produce explosive eruptions.
Why continents dint just stay in one place?
Natural disasters, such as earthquakes, tsunamis, and volcanic eruptions can move or destroy them.
Do basalt plateaus form from explosive or quiet eruptions?
Quiet eruptions are a characteristic of basalt lava flows and plateaus.
What do underwater volcanic eruptions cause?
Underwater eruptions cause tsunamis and cause lava to form and underwater ridge.
