What are negative and positive impacts volcanoes have?

Answer 1

Some say that volcanic soil is much more fertile than "regular" soil, so that would be a positive.

Volcano's release a LOT of energy. Releasing that energy through a volcano could prevent earthquakes. That's a positive.

Big volcanoes put lots of dust and ash into the air. This causes some really beautiful sunsets. that's a positive.

all that dust in the air often causes more rain to fall. that could be a positive.

Of course, depending on where the volcano hits, people often get killed and cities are destroyed. That's a negative.

Volcanoes are pretty unpredictable. That's a negative.

Dust, ash, and poison gasses in the air can make breathing difficult or even fatal to someone who might have Asthma or emphysema. That's a negative.

Some of the poison gases mix with water to form acid rain. That's a negative.

If the volcano is big enough, it can put enough dust and ash into the air that it can actually cool down the earth's atmosphere. This can happen for a couple of years. In this case crops don't grow correctly, and that is a negative.

Answer 2

Negative.

Cause destruction

Positive.

Only that if such erruption dont occur then one day all the pressure in the earch would be released at once causing million times more destruction.

Negative.

Volcanic activity can produce poisonous gases such as Carbon dioxide which can suffocate people.

Answer 4

Beneficials:

1. The land is more fertile as it is covered in mineral rich ashes.

2. The processes of making coal is shortened.

3. It can figure land into different shapes and forms eg making a slightly mountainous area into flat land.

4. Flames can destroy plants allowing them to repopulate in different areas.

5. Flames can force animals to move to a different area to repopulate making animal migration possible.

Harmful Effects:

1. The gases released from the volcano is extremely toxic and can lay waste to an area of land for a extended period of time.

2. The flames could destroy the plant life too much, making it impossible for them to repopulate pushing it to extinction.

3. The flames could annihalate a whole animal species instead of driving it away causing them to go extinct.

4. Human culture (eg monuments etc.) can be destroyed along with the eruption of the volcano.

5. Any human activity near the volcano will render the people certain to die.

Answer 5

what are 5 negative things about volcaneos

Answer 6

The volcanic ash is very fertile and can bring a very good harvest. The pyroclastic flow and the lava is very destractive and can caurse a lot of damedge to the serrounding area.

Answer 7

The negative effect is land is destroyed and lives are lost, but the positive effect is that after a period of time the land grows back and is lush.
