Volcanoes

Global Warming

Global Warming means that the rising of the temperature of the Earth and making eruptions to the mountains and the seas and also the ground. Global Warming started in the late 19th Century and it is getting worse every time days are passing because now it is getting worse like the one that happened in 2010 in Eyjafjallajokull it was 250 million cubic meters. The temperature of the world now became 0.8 *C. The green house effect is getting worse because when the gasses get trapped in the Earths atmosphere the sun light when it shines it wants to get out but it cant so thats why the Earths is getting worse anytime.


Volcanoes

A volcano is a opening in the earths surface that when the ocean on the bottom gets too hot it boils example when you boil water in a kettle and left the cap open when it gets at maximum point of boiling the water rises the same things with volcanoes the sea boils underneath and the water rises with the lava on its way it erupts. The volcanoes gas that volcanoes produce is deathly acidic like if you brought lava and poured it on your self you will burn in one second the same things with the volcano gas it travels 300 km per hour.


How Volcanoes are Harmful and
Helpful!!☹☹☹!!☺☺☺?


Volcanoes are harmful because they release a gas that can kill a human and anything on its way and can even sometimes destroy building it is depending on the strength of the volcano if it is strong it will destroy buildings but if it is weak it cant but it will damage the buildings. Volcanoes are helpful because when the volcano finishes the lava becomes soil. The soil is the best because it is very fertilized. Also it is very good for growing crops and other plants.

Volcanoes

There are 1510 active volcanoes in the world now and they are getting more every time. There is three parts for the volcano Crust, Mantle and Core. The crust is like a mountain then the magma rises to erupt then the core is the middle of the volcano. The Magma is the liquid rock inside the volcano it doesn't explode. The lava is the liquid rock that explodes from the volcano. The biggest volcano is the one in Hawai in Mauna Loa. There is 80% of the earth rock is volcanic origin. More than half of the worlds volcanoes form the ring of fire. The ring of fire is a circle of volcanoes in the earth.
