There is a crack in the earth then magma pushes through the crack.That forms lakes and rivers of lava.When lava cools 9t turns to rock.

First it gets so hot deep under the crust that the rock melts and now is magma. Magma pushes through the the cracks in the earth, this is called an eruption. Once it the magma spews onto the ground it is called lava. After the lava cools it hardens into rock.

Volcano's form by cracks or holes in the earth magma then goes up through. Which is now the eruption and then when the magma that just erupted is now called lava.

The magma pushes its way through the cracks. Then it has its eruption and the lava shoots out the top. Last the lava hardens and forms to rock.

First,the earths crust will crack and the lava will pop out which is called a volcanic eruption. Second, it will scatter into lakes, land, and rivers. Last it will start to dry up and crust up with things inside the dried up.

The magma pushes through the crust. The magma explodes through the top of a mountain. As the magma touches the top, It is now called lava. After a while the lava turns into rock.14

There are layers and when there is a crack in the crust it pushes lava up and can
cause an eruption and shots hot lava

I think the molten rock will fell down then the magma will goes up and goes up and goes up and then erupted.

Before: is that the volcano gathers to much heat and erupts.

During: the volcano melts everything in its path, including houses, people, and animals.

After: the volcano stops and all the magma melts into the ground and all the stuff that the volcano melted is all debris.

The cracks on the volcano pokes into the earths middle layer to make an eruption.After the lava ecsploids there are like lava rivers .Then the lava drys up C-23

1.they start to talk about how Vulcan is the god of fire.

2.It tells us that our planet is made up by many layers of rock and crust is the top layer.
orm.
3.volcanoes are formed by cracks or holes in the ground that poke through the earths crust.really it talks about how volcanoes form.C-11

I believe that before a volcanic eruption you can hear rumbling noises coming from the ground and feel the ground moving. Under the ground hot melted rock [magma] gets so hot that it streams through the cracks and the holes in the next layer.

Then during the volcanic eruption you could see red and orange magma [lava] spewing into the air. You could feel the temperature rise about 2 degrees. If your close to an erupting volcano get to a high place or as far away from it as you can.

After a volcanic eruption you would see either hard or hardening that is now black like rock.

Before an eruption magma tries to find holes to get out of. During a eruption lava flows out and mack rivers and lakes of lava.After an eruption the lava hardens and new land is formed.

Heat from the earths crust makes the magma heat up. When theres enough heat built up the magma searches for a way to escape from the inside to the outside. When the magma find a way out the magma exploads and the lava burns everything in it's path. When the lavas all melted the whole place looks burnt to pieces.

I don't think their is a god of fire. Well
the early Hawaiians told stories about Pele the god of fire. But she was chased by her sister from one island to another but then finely she stopped at the biggest island in Hawaii and lies in a volcano.

The magma bursts out of earth's crust. Then the magma will expold onto the surfuse. Once it has reached the surfuse, the magma is called lava. The lava will eventully turn into rock.

The magma underneath the earth's core is acctualy melted rock. The magma forces its way through many layers of the earth, building up pressure along the way. This pressure is so great that the magmabursts through a crack in the earth. The magma hits air and becomes lava. After a while, the lava cools into rock.
