What else can I help you with?
Can large areas be covered with layers of sedimentary rocks?
Yes, massive areas of Earth are covered by sedimentary rocks. A good geology map will tell you what rocks are in your area.
How can sedimentary rocks helpus learn about earths's past?
it is good
Why is sedimentary rock good for rock climbing?
Not all sedimentary rock is good for climbing. Some sedimentary rocks can easily break. Sedimentary rock can be very good for climbing because it often has interesting textures and holds. For example, welded tuft is a kind of sedimentary rock that is very good for climbing due to the large sediments that formed it. It makes for interesting holds and pockets
What is the relationship between sedimentary rocks and fossils?
When sedimentary rocks grow more layers small fossilised animals get caught between the layers. Ther fore when people chip away at the rock or erosion happens the fossilisd animals have been turned into fossils and fall out.
What are some igneous and sedimentary rocks?
Igneous rocks are made from magma. Magma is made of melted rocks. (When it is underground it is called magma, when it erupts on the surface of the earth, it is called lava. It's the same material though.) When magma/lava cools, it forms igneous rocks. There are many types of igneous rocks and the specific type of igneous rock can vary according to which minerals are present in the melted rock, how fast it cools, and the presence of things like water. Sedimentary rocks are made out of tiny pieces of debris. This can include tiny rocks, sand, clay, silt, and organic material. (Organic materials can vary from rotted leaves to tiny, shelled ocean creatures, or many other types of organic material.) These bits of material collect in an area, then through compaction and cementation, they stick together to form sedimentary rocks. Sedimentary rocks can also be formed when minerals are dissolved in water and are then resolidified. This type of sedimentary rock is called a chemical sedimentary rock. Oolitic limestone is a good example of this type of sedimentary rock.
One reason Tetragraptus is considered a good index fossil is that Tetragraptus?
evolved rapidly, had a wide geographic distribution, and had a relatively short geological range, making it useful for correlating sedimentary rocks in different locations.
What types of stones are most likely to contain fossils?
There are three basic types of rock; sedimentary, igneous and metamorphic. Igneous rocks are formed by volcanic action and don't contain fossils. Sedimentary rocks are formed, usually under water, by eroded material accumulating. Metamorphic rocks are formed when sedimentary rocks are changed by heating and/or pressure. From this, you can see that sedimentary rocks are the most likely to contain fossils, although metamorphic rocks also can contain fossils. Any sedimentary rock can contain fossils, but some make fossil hunting easier. Shales and mudstones are particularly good; chalk is pretty much entirely made of fossils - it's formed of skeletons of small organisms, but its difficult to see the individual fossils.
Are skipping stones made from sedimentary rocks?
You can find "skipping stones" from any of the classic rock formations: sedimentary, igneous, metamorphic, and mineral. The only criterion is a good skipping stone needs to be round and a thickness much thinner than the width and height.
What are sedimentary rocks made from dead plants or animals compacted together?
The only good example of this is chalk, which is made from the compacted shells of tiny marine organisms called diatoms. Other than that, animal and plant remains do not tend to form rocks, although the hard parts may form fossils.
What rock is copper found in?
Copper is actually an element, although it is present in rocks as a mineral. Physically, it's a metal mostly used for the conduction of electricity. As for other rocks, granite and basalt are igneous rocks, as in they were formed straight from a flow of lava. They will be generally of one colour and are not easy to break. Sedimentary rocks include limestone, sandstone, and other softer rocks. They are basically layers of mud that have hardened and compressed into rock over millions of years. You can find lots of fossils in sedimentary rocks. Beds of sedimentary rock will look like many layers sandwiched on top of each other and should be fairly brittle and easy to break. Metamorphic rock is sedimentary rock that has fused and reformed into "igneous" or solid rock because of heat, pressure and time. The sedimentary rock was heated under the surface of the earth, re-fused into a solid mass, and then cooled. Some rocks will have different coloured bands around them, this is a good indication of metamorphic process.
A classification scheme that grouped plutonic and metamorphic rocks together and sedimentary and volcanic rocks together would be based on what?
This classification scheme would likely be based on the genesis or origin of the rocks, as plutonic and metamorphic rocks are both associated with processes occurring beneath the Earth's surface (igneous intrusion and metamorphism), while sedimentary and volcanic rocks form at or near the Earth's surface through sedimentation and volcanic activity, respectively.
