Answer and Explanation: Geologists and volcanologists, a type of geologist specializing in volcanoes, conclude that volcanoes are constructive forces because they often create new landforms and build on existing ones .
Is a volcanic eruption constructive or destructive Why do you think so?
Volcanic eruptions are constructive forces when they cause mountains to form . However, explosive volcanic eruptions can be destructive forces if they blow apart mountains, leaving craters. Landforms are also worn down by the destructive forces of weathering and erosion.
Are volcanoes constructive or destructive?
To scientists, volcanoes are known as “constructive” forces . That is, volcanoes often result in the construction of new landforms. “Destructive” forces are those like erosion or weathering in which landforms are broken down into smaller pieces like soil and sand.
What are the constructive and destructive effects of volcanoes?
Discuss – Constructive effects of volcanic eruptions – Formation of Fertile Soils- Volcanic soils, Creation of new land, Provides useful materials, Geothermal energy, Volcano Tourism etc. Destructive effects of the volcanoes include – mudflow or debris flow that contains magma, Nuée ardentes, Environmental damage etc .
Are volcanoes always destructive?
Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive . ... Volcanic eruptions can result in additional threats to health, such as floods, mudslides, power outages, drinking water contamination, and wildfires.
What are 3 examples of constructive forces?
- Sediment (Deltas, sand dunes, etc.)
- Tectonic Plates Colliding (Mountains)
- Crust deformation (Folding or Faulting)
- Volcanoes (makes Islands)
Is water constructive or destructive?
Water carries sediment down river and as the river becomes more shallow, the sediment is deposited, forming landforms such as deltas. Mountains are also an example of a slow constructive force due to two tectonic plates being pushed into each other.
What are the three constructive effects of volcanoes?
Constructive effects of volcanic eruptions – Formation of Fertile Soils – Volcanic soils, Creation of new land, Provides useful materials, Geothermal energy, Volcano Tourism etc.
What are the constructive effect?
1 serving to build or improve ; positive. constructive criticism. 2 (Law) deduced by inference or construction; not expressed but inferred. 3 (Law) having an implied legal effect.
What are three destructive effects of volcanoes?
- Volcanoes can change the weather. They can cause rain, thunder and lightning. ...
- Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. ...
- Lava can kill plants and animals too.
Can a dead volcano come back to life?
Volcanoes typically are categorized thusly: active (a volcano that has erupted in the past 10,000 years), erupting (an active volcano that is experiencing an eruption), dormant (an active volcano that has the potential to erupt again), and extinct (a volcano that has not erupted in over 10,000 years and is unlikely to ...
How do you know if the volcano is active?
If a volcano has erupted since the last Ice Age —in the last 10,000 years or so—and is still showing activity like lava and ash flows or gas emissions, it's considered to be active. If a volcano hasn't erupted in the last 10,000 years, but scientists think it will erupt again, it's considered dormant.
Can dead volcanoes be revived?
An extinct volcano by definition is dead volcano, which has not erupted in the last 10,000 years and is not expected to ever erupt again .
What is the constructive process?
Constructive processes are things that happen to the earth that build it up or make positive changes . One example of a constructive process is when sand is deposited onto a river bank by the running water. This builds up the river bank, making it higher.
What are examples of constructive and destructive forces?
Collection and analysis of data indicates that constructive forces include crustal deformation, faulting, volcanic eruption and deposition of sediment , while destructive forces include weathering and erosion. I can explain how constructive and destructive forces affect the nature of landforms on Earth.
Is a sand dune constructive or destructive?
Wind – sand transported by the wind creates sand dunes. Water – bits of soil and rock can be carried downstream and deposited causing deltas.
