Volcanoes cause a change in immediate weather resulting in cloudcover, rain and lightning. This is due to the property that the volcanic ash particles have; i.e. they promote the production of rain particles at a molecular level. There are also long term climatic effects of volcanic eruptions which are harder to understand. If the ash reaches the stratusphere it cannot be diminished by rain and therefore contributes to the greenhouse or warming sex. Obviously there are also immediate physical damages caused by the lavaflows and acid seeping into surrounding water but this damage is relatively small in comparison to the climatic significance of Volcanoes Electricity and even telephone supplies can be cut off because of the large explotion that has caused a strong vibration............................

RafaA destructive result of a volcanic eruption is what the lava does to the surrounding plant life; no plants can stand the hot temperature of molten lava, and generally die even before coming in contact with the substance.
A constructive result of a volcanic eruption comes when the volcano is out at sea or at least on an island; the lava, when it flows into the sea and cools over a period of time will eventually become another landmass, which is how Hawaii was probably formed.
CONSTRUCTIVE EFFECTS OF VOLCANOES
- The soil produced by lava can be fertile and beneficial e.g. coffee growing regions of South America.
- New land can be created e.g. the island of Surtsey off the coast of Iceland.
- Volcanic activity my produce hot springs or geysers which gush out hot water from below the ground. These can be used to help generate electricity as in New Zealand.
- Volcanoes are often important tourist attractions.
- The high level of heat and activity inside the earth can provide opportunities for generating geothermal energy.
It helps release the stored energy inside the earth
The destructive effects of volcanic ash much outweigh the constructive effects. Significant amounts of volcanic ash can immediately destroy most of a local ecosystem, as well as the collapse of roofs on man-made structures. In addition, ash can become so dense that it can block sunlight, lowering temperatures and causing power outages/breakdown of communication. In addition, ash can be very hazardous to humans, especially if it is in the form of a pyroclastic flow. Pyroclastic flows are 'avalanches' of hot ash, gases and rocks that flow at high speeds, deadly to the touch and often unable to outrun. Finally, planes are unable to fly through ash clouds, due to the blinding and debilitating capabilities of it. However, over time ashfall can lead to the creation of very fertile soils.

What are earths destructive forces and constructive forces?
Rain,Volcanoes and Hurricanes are both destructive and constructive. RAIN: constructive: plant growth and water for animals. destructive: flooding and erosion VOLCANOES: constructive: new earth surface. destructive: lava flow and ash cloud. HURRICANES: constructive: rain and reduction of gases in the air. destructive: winds and flooding.
Is a volocano a construtive or deconstructive?
A volcano is typically considered a constructive force in geology because it builds up land through the deposition of lava, ash, and other volcanic materials. However, volcanic activity can also be destructive due to eruptions, which can cause widespread damage and reshape the landscape.
What are four examples of natural forces that fit both constructive and destructive forces?
Water can be a constructive force by shaping landforms through erosion and deposition, but it can also be destructive in the form of floods and tsunamis. Wind can create sand dunes and reshape landscapes constructively, but it can also lead to destructive forces such as hurricanes and tornadoes. Volcanoes can build new landforms like islands through lava flows, but they can also cause destruction through eruptions, ash fall, and volcanic gases. Earthquakes can create mountains and valleys through tectonic activity, but they can also be destructive in terms of ground shaking, tsunamis, and landslides.
Does volcanic ash create basalt?
No. While volcanic ash can have a basaltic composition, it usually does not. Basalt forms from lava. Volcanic ash forms tuff.
What is made of volcanic ash cinders and bombs?
Tephra consists of volcanic ash, cinders, and volcanic bombs. Tephra is ejected during explosive volcanic eruptions and can vary in size from tiny ash particles to large volcanic bombs.
