Fissure eruptions on continents can lead to the formation of extensive lava plateaus or basalt plains. As magma erupts from long cracks in the Earth's crust, it can cover large areas with layers of basaltic lava flows, creating flat landscapes with relatively low relief. Over time, these eruptions can build up thick sequences of basaltic rocks that form distinctive geological features on the continents.
What else can I help you with?
When a fissure eruptions occur on continents?
Fissure eruptions on continents occur when tectonic forces cause the Earth's crust to crack open and release magma. This magma can flow out of the fissure as lava, creating long lines of volcanic activity. Fissure eruptions can be more gradual and less explosive compared to central vent eruptions.
What is a long crack from which lava flows through?
A long crack from which lava flows through is called a fissure. These fissures can be found along volcanic zones and can release lava during volcanic eruptions.
Are continents and plates not the same?
No, continents and plates are not the same. Continents are large land masses that form the Earth's surface, while tectonic plates are pieces of the Earth's lithosphere that move and interact with each other, causing geological phenomena like earthquakes and volcanic eruptions. Continents are located on top of tectonic plates and can be made up of one or more plates.
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.
How are magmatic materials transported to the surface?
Magmatic materials are transported to the surface through volcanic eruptions. When pressure builds up in the magma chamber below the surface, it can force the magma to erupt through a vent or fissure, releasing gases and molten rock onto the Earth's surface. This process can result in different types of volcanic eruptions, such as explosive eruptions or effusive eruptions.

What is a long crack from which lava flows through?
A long crack from which lava flows through is called a fissure. These fissures can be found along volcanic zones and can release lava during volcanic 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 the lava called from a crack in earth?
The lava that flows from a crack in the Earth's surface is called fissure or fissure lava. It typically arises from volcanic eruptions along long cracks in the ground, known as fissures, rather than a central volcanic vent.
Are continents and plates not the same?
No, continents and plates are not the same. Continents are large land masses that form the Earth's surface, while tectonic plates are pieces of the Earth's lithosphere that move and interact with each other, causing geological phenomena like earthquakes and volcanic eruptions.

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
How are magmatic materials transported to the surface?

This process can result in different types of volcanic eruptions, such as explosive eruptions or effusive eruptions.
What happens at a continent-continent convergence?
When two continents converge, they often form mountain ranges due to the collision of their landmasses. This can also lead to intense geological activity such as earthquakes and volcanic eruptions. Over time, the continents may continue to collide and push against each other, causing further changes to the landscape.
Can smaller continents form from larger continents by rifting?
No. Its through paleomagnetism.
