How do sedimentary rocks form? How much of the earth is made of sedimentary rock? How do these rocks give us an insight into Earth's history? List some names of some sedimentary rocks.
Sedimentary rocks are formed when sediments, such as sand, rock fragments, mud, and dirt, build up and are pressed together over very long periods of time. Some sedimentary rocks are limestone and shale. Sedimentary rock forms in water, and water makes up 70% of the earth, so this type of rock is common everywhere.
Sedimentary rocks form when sediment in a river piles on top of its self and hardens into rock. Sedimentary rocks include shale, sandstone,and coal. Sedimentary rock forms mostly in water and the Earth is 70% water so that is how common sedimentary rocks are. Sedimentary rock is what we find most of are fossils in so that is how sedimentary rock can tell us about are past.
Sedimentary rocks form by river piles and hardens into rock. Different types of rocks are coal, sandstone and shale. Sedimentary rocks are formed in mostly water. Fossils are found in mostly sedimentary rocks.
70% of all of the rocks on earth are sedimentary rocks. Sedimentary rocks form when sediments pile up and are pressed together in layers. As sedimentary rocks form remains of dead animals or plants can be pressed into them creating a fossil; we can learn about past life on earth by studying these fossils. Some types of sedimentary rocks include: Sandstone, Shale, Limestone, Conglomerate, etc.
Mrs.Hoffman, Most sedimentary rocks form under water. Most of the earth has been covered by water some time in the past.70% of the earth is covered by water now.So sedimentary rocks are common all over the world. Sandstone Limestone Siltstone Chalk
They are made up of rocks that have been erouded.70% of earth is made up of sediments.They can creat fosles. Sandstone,limestone,shale, and conglomarte.
Sedimentary rocks are formed when sediments bulid up and press together over very long periods time. Since this rock can be found almost anywhere 70% is made up of the earth. We find fossils in mostly Sedimentary rocks. Limestone, Sandstone.
sedimentary rocks come from the earth's surface the types of sedimentary rocks are limestone and sandstone we find them in rivers and when volcanoes expload.

Sedimentary rocks are formed by weathering. These types include sandstone, limestone, shale & even conglomerate.-Dominic Deutsch

@katherine,
ReplyDeleteI agree with you because i felt your answer was good and long and had full detail.

ReplyDeletethey are made of sediments quarts and bits of other rocks.
