Magma is the first part of the rock cycle Magma starts the whole rock cycle. Magma is melted rock that explodes from a volcano. It explodes because of all of the pressure and heat that builds up and makes more heat so magma is the start of the whole rock cycle.
Igneous rock is the second start of the rock cycle igneous rock is magma that is cooled. Igneous rock has air pockets in it and the air pockets are just the air that got stuck in the magma and dried up and the air stayed in it as it was drying up and that's why the igneous rock has air pockets in in
Sediments are the third part of the rock cycle is small igneous rock that has been broken down in to small bits. Igneous gets broken down over time by water and wind also ice so it just brakes down and becomes sediments. Sediments are everywhere they are on trails on the bottom of lakes and rivers they are small pebbles of rock that we pretty much see all the time.
Sedimentary is the fourth part of the rock cycle. Sedimentary is kinda like sediments but not really so sedimentary is a rock that has dead plants and animals and bugs. Sedimentary is a rock that has straight layers and that is caused by pressure and heat. The layers are made up of the dead plants and animals and bugs.
Metamorphic rock is the fifth part of the rock cycle. Metamorphic rock is like sedimentary rock but metamorphic rock also has layers like sedimentary but the layers are all bunched up and messed up. The layers are bunched up because of even more heat and pressure the sedimentary also got heat and pressure but metamorphic got even more heat and pressure that is why all of the layers are all miked up and bunched up.
After metamorphic rock get more and more heat and pressure it will then melt and the whole rock cycle will start over and it will start back a magma. That is how the rock cycle works and how it just keeps going over and over and over again but it takes a long time for the rock cycle to get through one rotation. It takes years and years to got through one rock cycle just because it takes a really long time doesn't mean it's not there. The rock cycle is so amazing to learn about it takes awhile to really understand the rock cycle but once you figure it out it's really simple and it makes it supper easy to explain to someone else for them to know and for them to explain to someone i really liked to learn the rock cycle it was so fun to learn about so teach some one to learn the rock cycle so they can teach someone else so that's all i have to say about the rock cycle.
