volcanic eruptions may cause mass extinctions or volcanic haze.a mass extinction is when a large number of species die out over a short period of geologic time and volcanic haze is when the gases of an eruption cause a haze and block out sunshine, causing a mass extinction.

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.
Vulcanicity is a process through which gaseous, liquid and solid materials are forced out of the earths crust to the earths surface. Volcanicity is the process where igneous materials reaches the earths surface from the earths crust to the earth surface
...because of diz volcanic eruption,many lives will be lost,properties will be destruct...
Mountain ranges such as Himalayas may be formed from magma during volcanicity takes place in volcanic mountains.
The study of volcanoes is found under Physical Geography. It is taught in the topic Volcanicity. Which is a part of Orogenesis, ie origin of rocks, volcanoes and other landforms of igneous properties.
Magma in mantal is under great heat and high temperature. Once there is a crack or we called a line of weakness appears on crust's surface,magma would escae to the surface from mantal.Volcanic ashes,gases and magma would throw out and causes volcanic eruptions.
volcanicity is the process where by magma in the interior of the earth crust forced it way out to the earth surface cause by intense pressure in the interior of the crust there by forcing the earth crust to expand and causing a crack which will intend force it self through flowing out to form hard igneous rocks
current has five effects. 1. physical effects 2. xray effects 3. heating effects 4. chemical effects 5.magnetic effects.
Adobe after effects is a professional special effects software for creating insdustry standard visual effects.
how do we separate the effects of specific and non specific drug effects
