Rava: Hi, my name is Rava the Lava.
Careful! Don't touch me.
Rava: See, I am one thousand degrees Celsius. I'm hot!
Rava: This is my friend Java the Lava.
She's hot too.
Java: Hi there! It's nice to meet you.
Rava: We are not from here.
We come from a very different place.
Java: Hey Rava, let's tell them how we got here.
Rava: That's a great idea!
Today, we came out of a volcano.
Rava: Before that, we were magma, which means melted rock.
Rava: We are from deep in the earth.
Java: Let's go have a look!
Java: When you travel down into the earth, it gets hotter and hotter.
Java: Thirty kilometers down, all the rock is melted.
Rava: Down here used to be our home.
We lived here with the magma.
Rava: Everything is very hot.
Java: When rock turns into magma, it makes gas.
Java: It becomes very crowded down here.
Java: So the gas pushes us up to the surface.
Java: The gas and the magma try to find cracks in the earth's crust.
Java: We push everywhere until we find a crack.
Rava: Hey guys, I found a crack over here!
Rava: When we find a crack in the crust, we climb up it.
Java: We rise and we rise, pushing through the earth.
Rava: It is hard work.
But soon we are almost at the surface of the earth.
Java: When we get to the top, we all work together and [n3@push through the earth's crust.
Rava: Push! We push so hard that we fly up high into the sky.
Java: Whee! We have made it to the surface.
Rava: It is much cooler here.
Ah, I like it here.
Java: Up here the gas, the air, and the magma all mix into one.
Java: Together they make lava.
Rava: That is how we got here today.
Rava: Most people do not like lava because we destroy their cities.
Java: But we did not know there was a city here!
Rava: Watch out! Get out of the way! We can't stop.
Java: Now we are beginning to cool down.
Rava: Soon we will become rock.
Rava: Then, we will be part of a volcanic mountain.
Java: Volcanoes make very large mountains.
Rava: Many mountains were made by lava that cooled into rock.
Java: There are the Smokey Mountains in the eastern United States.
Rava: There is Mount Kenya in Africa.
Java: And many, many more.
Sometimes volcanoes erupt in the ocean.
Java: When this happens, a new island is made.
Rava: The islands of Hawaii were made from a volcano.
Rava: Long ago, magma pushed through the earth's crust under the ocean.
Rava: When the lava cooled, the new islands of Hawaii were born.
Rava: We must say good-bye.
We are becoming hard.
Soon we will be rock.
Java: Good-bye!
Rava: So long!
