What else can I help you with?
Why does a constructive plate boundary produce a shield shape and a destructive plate boundary produce a cone shape?
Its to do with the viscosity of the lava, the thicker (more viscous) the lava the slower and less far it will travel making a shield volcano. This happens on a constructive plate boundary. on a destructive plate boundary the lava is less viscous and runs further making a conical shaped volcano
How volcanoes can be destructive?
Well, volcano are destructive because they erupt lava and they are very destructive :D
Is lava a constructive or destructive?
It is constructive: the lava builds into a new structure.
What is the consistency of lava in the composite volcanoes?
Composite volcanoes are found on destructive plate margins , where the oceanic crust sinks beneath the continental crust. Composite volcanoes have the following characteristics: Acidic lava, which is very viscous (sticky). Steep sides as the lava doesn't flow very far before it solidifies
Is eyjafjallajokull on a plate boundry?
Yes. It is believed to have erupted in 2010 twice because of the constructive margin. The plates were pulled apart by convection currents then because of this basalt lava seeps in to form a new crust beneath the sea and existing volcano. Much of the magma was intruded as dolerite dykes (thin sheets of igneous rock.) New lava and dykes then added extra crust at each side of the spreading ridge.
Are lava combs constructive or destructive?
Lava combs are considered destructive features because they are formed by volcanic eruptions that can cause widespread damage to the surrounding environment. They are often associated with explosive eruptions and the deposition of lava and other volcanic materials, which can lead to destruction of landscapes and ecosystems.
Is the El chichon volcano located along colliding plate boundaries?
Yes, the El Chichon volcano is located along the boundary between the North American Plate and the Cocos Plate in southern Mexico. This boundary is a convergent plate boundary where the Cocos Plate is being subducted beneath the North American Plate, leading to magma generation and volcanic activity.
Are lava flows harmful?
Yes. Lava flows can be extremely destructive. Since most lava flows move slowly, though, relatively few people have been killed by them.
What are some landforms that are constructive and destructive?
Destructive:SlumpsCreepsMudslidesConstructive:Mid-Ocean ridgeIslands made of Molten Lava
Was the paricutin volcona destructive?
Yes, Paricutin volcano in Mexico was destructive. It erupted in 1943, causing the evacuation of nearby villages and covering surrounding areas with lava, ash, and debris.
Is lava fluid?
Lava of relatively low viscosity (relatively low silica content, so basic rock such as basalt). Associated with constructive plate margins and with intra-plate volcanoes such as Hawaii.
Put these eruption types in order from most destructive to least destructive.?
When eruption types are arranged from most destructive to least, it is in descending order.
