As the magma cools, different crystals form at different temperatures, undergoing crystallization.]]> 2022-03-02 20:52:03 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074402712 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074405152 Liquid magma also turns into a solid — a rock — when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind.]]> 2022-03-02 20:54:06 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074405152 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074406478 Extrusive, or volcanic, igneous rocks are formed when molten hot material cools and solidifies.]]> 2022-03-02 20:55:15 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074406478 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074408801 The formation of clastic and organic rocks begins with the weathering, or breaking down, of the exposed rock into small fragments. Through the process of erosion, these fragments are removed from their source and transported by wind, water, ice, or biological activity to a new location.]]> 2022-03-02 20:57:11 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074408801 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074410710 Once the sand particles are sedimented, they create layers which are soon covered by another layer of new sediments and the process goes on. This gives rise to pressure on the sedimented layers below.]]> 2022-03-02 20:58:46 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074410710 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074413137 Compaction is when sediment is pushed together by the weight of water and other sediment pushing down on it. Cementation is the last stage in the cycle and happens when sediment is glued together by minerals such as silica and calcium carbonate as the minerals infiltrate pore space between compacted sediment.]]> 2022-03-02 21:00:32 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074413137 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074414899 The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.]]> 2022-03-02 21:01:41 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074414899 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074577198 The magma bursts through Earth's surface in the form of a volcano. Heat and pressure deep in the Earth makes some rocks change to metamorphic rock. Layers of rock get squashed and packed together and gradually harden to form sedimentary rock. The igneous rock gets broken down by weather, and the cycle begins again.]]> 2022-03-02 23:51:45 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074577198 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074578814 Metamorphic rocks are rocks that have been changed from their original form by immense heat or pressure. Metamorphic rocks have two classes: foliated and nonfoliated. When a rock with flat or elongated minerals is put under immense pressure, the minerals line up in layers, creating foliation.]]> 2022-03-02 23:53:29 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074578814 kludden2 https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074581179 The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius to melt a rock, turning it into a substance called magma.]]> 2022-03-02 23:56:04 UTC https://padlet.com/kludden2/t0z2xlhc2wqhzmm3/wish/2074581179
