Harmony, Heaven, and Hope were the 3 sisters that did everything together. Their grandmother just recently died though, sadly. The grandma loved science and left them each a necklace with a different gemstone: a Periodot, Amythest, and a Diamond. Little did the sisters know, when they touched their necklaces 3 times at the same time, they would get transported to the start of the Rock Cycle, at the begining of time.
Hope: Hey, aren't these bracelets our grandmother gave us the coolest?!
Harmony: Yeah. Sad that she died, though
Hope: Not now. Harmony is going to braid my hair.
(The three sisters see a flash of light, and the next thing they know, they're floating in zero gravity, looking at the Earth, which is covered in active volcanos spewing lava.)
Heaven: Hey, where are we?
Hope: We have to stick together
Hope: Just because we are in zero gravity does not mean we should flip, Harmony!
(A woman fades into the scene.)
Jackie: Hello, I am Jackie. I am here to teach you about the rock cycle. Right now we are at the first stage of the Earth when the Earth was just lava and magma. Lava is a hot substance that has been erupted from a volcano or
has not haven a erosion. Magma is a hot substance that has not been erupted yet and is still under the Earth's surface still heating.
Jackie: As you can see this is Igneous rock. Igneous rock is formed through the cooling and solidification of magma or lava. In addition there is Extrusive Igneous Rocks. Extrusive igneous rocks form when magma reaches the Earth's surface a volcano and cools quickly. Most extrusive (volcanic) rocks have small crystals. Examples include basalt, rhyolite, andesite, and obsidian.
Jackie: Here is another important rock Sedimentrary rock. This rock has formed through the deposition and solidification of sediment, especially sediment transported by water (rivers, lakes, and oceans), ice ( glaciers ), and wind. Sedimentary rocks are often deposited in layers, and frequently contain fossils. In addition Limestone and Shale are common sedimentary rocks.
Jackie: One of the last rocks I shall teach you about is Metamorphic. Metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change.
Jackie: Also dont forget the earth is made into different parts.
Heaven: Woah that's so cool!
Jackie: Oppps I almost forgot to teach you about Weathering. Weathering is the process by which rocks are broken down into small grains and soil. Weathering can happen through rainfall, ice formation, or the action of living things, such as algae and plant roots. It is part of the geological cycle. This process break' s rocks.
Hope: Wow so these rock's can be anywhere!
Jackie: Exactly Lets fast foward to Earth now in the present.
Jackie: Here we are. You see all these stones and rocks such as Coal, Granite, Limestone, Marble, Obisdian, Quartizite, Sandstone all come from the 3 important rocks that I tought you about. They come from each of there cycle. They are all important. Any rock at that is important. My purpose here is to teach humans that rocks are important because in the future we have none.
Heaven: Wow this is crazy.
Jackie: Yes I know, well I have done my job for teaching you about the rock cycle know it is time for you to go. Remember take care of rocks and spread my lessons goodbye Heaven, Harmony, and Hope.
(The three sisters see a another flash of light, and the next thing they know, they're back in there bed's and it is morning)
Mom: Goodmorning Harmony, Hope and Heaven did you sleep well?
(The three sisters look at each other with a certain look of mystey and exitment that they can go visit the rock cycle anytime and tell people about rocks and how they are important.)
