1 Volcanoes a volcano is …
In volcanoes there is a thing called magma and there is lava and lava is melted rock and it is hotter than the sun. Magma is melted rock under the earths crust.

2 The solar system Earth is not the only planet that has volcanoes so I am giving you some information about the solar system

3 All about planets starting with uranus…
From the sun Uranus is 2,871 million km The orbit of the sun is 30,684 days The number of moons Uranus has is 27 The mass of Uranus is 14.6 x earth

4 All about Neptune… Neptune The distance from sun is 4,496 million km
The orbit of sun is 60,190 days The number of moons Neptune has is 13 The mass of Neptune is 17 x earth

5 About Mars… Mars The distance from the sun is 229 million km
The orbit of the sun is days Mars has 2 moons The mass of mars is 10% of earth

6 About Mercury… Mercury The distant from the sun is 57 million km
The orbit of sun is days Mercury has 0 moons

7 About venus Distance from the sun is 107 million km
The orbit of the sun is days Number of moons Venus has is 0

8 All about the earth Distance from sun is 150 million km
The orbit of the sun is days Number of moons earth has is 1 The mass of the earth is one hole earth

9 All about jupiter The distance from the sun is 777 million km
The orbit of the sun is days The number of moons Jupiter has is 50 The mass of Jupiter is 317 x earth

10 All about Saturn The distance from the sun is 1,429 million km
The orbit of the sun is 10,759.2 days The number of moons Saturn has is 53 The mass of Saturn is 95 x earth

11 How do volcanos erupt? First a volcano makes something called magma from melted rock. The magma goes through a currency. It has to form at the bottom of the volcano and then start its way up the main vent. The main vent is a hole that is in the volcano and when the volcano is ready to erupt the lava is at the top of the main vent. The magma goes up the main vent slowly while it is still getting hotter. lava is hot, running rock that flows out of a volcano. Lava can sometimes travel very fast like a red, hot river. When the magma is about halfway up the main vent, it turns into lava. Lava is a very hot liquid which burns the remaining rocks from the magma. The lava slowly continues up the main vent. While going up the laver continues to get hotter and hotter. Ash and rocks are collected and the lava is getting hotter and hotter while the lava is continuing its way up the main vent. When the lava is at the top of the main vent the volcano erupts. The lava blasts out of the volcano along whith ash, rocks, and a cloud of dust that is very thick.

12 Here are some pictures of volcanos erupting…
This a picture of a volcano that has just erupted. When the erupting has stopped, the smoke is still there. The smoke goes so fare up the sky if reaches the clouds and so the smoke is weight and brown. You can sea that the smoke has pushed the clouds out of the way so you can sea the volcano.
