Those pieces could collect in a river bed, flood plain, be swept into sand dunes, or collected on the ground. Over time, layers of the rock fragments build up and way down on one another. They get fused together and become sedimentary rock.]]> 2017-04-24 17:26:47 UTC https://padlet.com/121928/24jmxq922p40/wish/167911282 121928 https://padlet.com/121928/24jmxq922p40/wish/167912928 When heat and pressure occur in a rock. It can happen when friction of the Earth's shifting crust, pressure deep within the Earth, or radioactive decay. ]]> 2017-04-24 17:31:16 UTC https://padlet.com/121928/24jmxq922p40/wish/167912928 121928 https://padlet.com/121928/24jmxq922p40/wish/167914330 When rocks get super heated deep within the Earth they melt and form into magma. When magma rises up to the surface, or moves up in the Earth's crust, it begins to cool and becomes an igneous rock.

A metamorphic rock can change into an igneous rock. An igneous rock can change into a sedimantary rock. A sedimentary rock can change into a metamorphic rock. There are many more ways.  ]]> 2017-04-24 17:47:37 UTC https://padlet.com/121928/24jmxq922p40/wish/167919009 121928 https://padlet.com/121928/24jmxq922p40/wish/167990656 Any type of rock can be formed into a metamorphic, igneous, or sedimentary rock. To become an igneous rock, a sedimentary or metamorphic rock must get heated and melt to form magma. When the magma rises, it cools and can become igneous. To become a metamorphic rock, an igneous or sedimentary rock should be heated and applied with pressure. Then it becomes a metamorphic rock. To become a sedimentary rock, a metamorphic or igneous rock would need to be broken down into tiny pieces and collected in a river bed, flood, etc. Layers of rock fragments build up and way down on each other. They get fused together to become sedimentary. All rocks can turn into each different form if these consequences apply.]]> 2017-04-25 00:53:00 UTC https://padlet.com/121928/24jmxq922p40/wish/167990656 121928 https://padlet.com/121928/24jmxq922p40/wish/167991666 Fossils are important because they give scientists information on different types of insects, animals, plants, etc. from the past. If we did not have fossils we would not know much about the different animals there were before.]]> 2017-04-25 01:06:48 UTC https://padlet.com/121928/24jmxq922p40/wish/167991666
