IT'S GONNA BLOW!!!!!!

Volcanic eruption
volcanoes are openings in the earths crust created when molten material under the crust is ejected upward through the surface. A volcanic eruption occurs when magma rises into cracks or weak spots of the Earth's crust. Pressure builds up inside the Earth causes a plate movement. The magma explodes to the surface causing a volcanic eruption.
Negative effects after a Volcano Erupts
Negative Atmosphere
When the ash rises from the volcano to the sky, the smoke blocks the sun causing plants to die.
Negative water
As the ash falls it mixes with the water and it creates a fast moving mud slide that is dangerous to people.
Negative Surface
When the lava flows out it covers the ground and it destroys everything in sight(plants, animals and destroy homes/community)
Positive Effects after a Volcano
Positive Atmosphere
When the volcano explodes it release in energy along fault lines increase the amount of geothermal energy.
Positive water
The change in the environment causes rain clouds to form, creating greater rainfall.
Positive surface
When lave covers the ground later it break downs and in-riches the soil with nutrients.
How the habitat, food webs, & biodiversity are affected
Volcanic eruptions not only affect the habitat, but the food webs and biodiversity too. Eruptions can affect the habitat because they kill plants (smoke cover sun and the plants not being able to get sunlight needed for growth) and animals in that environment. That would then affect the food webs because if a large amount of a certain species were killed by the volcano, predators would not be able to eat due to the lack of prey. Since they would not eat, the predators would begin to die. In the end animals would continue to die causing a domino effect also can be described as if one species died the species that eats wouldn't have a food source then it would die and then it happening to the next species that eats it, causing that domino effect. Biodiversity is then affected. Since more and more species begin to die out, this decreases biodiversity and sustainability.
