They are naturally occurring aggregates of one or more minerals. There are three types of rocks in the rock cycle: sedimentary, igneous, and metamorphic. Plate tectonic movement is responsible for the recycling of rock materials and is the driving force of the rock cycle. This whole processes will be explained by my "rocking" organizer, I know that joke quaked you up!]]> 2019-03-29 18:51:20 UTC https://padlet.com/1836501/69rpl1cypwto/wish/346676939 1836501 https://padlet.com/1836501/69rpl1cypwto/wish/347343845 The first type of rock we are going to talk about is igneous rock. Igneous rock  is formed through the cooling and solidification of magma or lava. Igneous rock that forms when magma hardens beneath Earths surface is called intrusive rock and an example of this is granite. Igneous rock that forms forms from lava one Earths surface is called extrusive rock and an example of this is basalt. This is an image of a obsidian rock, an example of an igneous rock. ]]> 2019-04-01 18:39:45 UTC https://padlet.com/1836501/69rpl1cypwto/wish/347343845 1836501 https://padlet.com/1836501/69rpl1cypwto/wish/347441001 Boys and girls it gets more intersting! Another type of rock we are going to talk about is sedimentary rock. Sedimentary rock is formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface. Weather and erosion produce sediments, after sediments are deposited, they undergo compaction.  Types of sedimentary rock is clastic, organic, and chemical. Clastic rocks are composed of fragments, or clasts, of pre-existing minerals and rock. Organic rocks contains significant amounts of organic carbon. The most common types include coal, lignite, oil shale, or black shale. Chemical rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. This is an image of a rock salt rock, an sedimentary rock. ]]> 2019-04-02 01:41:08 UTC https://padlet.com/1836501/69rpl1cypwto/wish/347441001 1836501 https://padlet.com/1836501/69rpl1cypwto/wish/347444272 Now the last type of rock we are going to be talking about is metamorphic rock. Metamorphic rock is  the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is subjected to heat and pressure, causing profound physical or chemical change. There are two metamorphic rocks foliated and nonfoliated. Foliated rock is, foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. Nonfoliated rock are hornfels, marble, quartzite, and novaculite do not have a layered or banded appearance. Some examples of metamorphic rock are anthracite, quartzite, marble, slate, granulite, gneiss and schist. This is an image of gneiss, an metamorphic rock. ]]> 2019-04-02 01:58:30 UTC https://padlet.com/1836501/69rpl1cypwto/wish/347444272 1836501 https://padlet.com/1836501/69rpl1cypwto/wish/347445460 Now boys and girls we have sadly come to an end. I hope you now know the three types of rocks that change through the rock cycle, igneous, sedimentary, and metamorphic. To thank you for absorbing all that knowledge I will tell you a joke! Whats another name for a clever duck? A wise quacker. Goodbye boys and girls, Ludwig Von Drake. ]]> 2019-04-02 02:06:59 UTC https://padlet.com/1836501/69rpl1cypwto/wish/347445460 1836501 https://padlet.com/1836501/69rpl1cypwto/wish/347446840  http://www.mineralogy4kids.org/rock-cycle/igneous-rocks
