Rocks found in a river bed would typically be what type of rocks?
Sedimentary, Igneous, and/or Metamorphic
What kind of rock is river stone?
Not necessarily always sedimentary. It depends on the rock type of the surrounding rocks, which erode into the stream bed. It could be sed., metamorphic, or igneous.
Is a plateau created by sediment deposits?
Generally, Yes, but not necessarily. Plateaus are generally created by an upwards thrust of the crust, pushing a flat rock bed further up than the surrounding area. The rock beds closest to the surface are usually either sedimentary rock layers (which are created by compacted sediment deposits) or sedimentary rock layers with intrusive igneous rocks. There are some plateaus that have metamorphic rock beds because the crust has been significantly eroded, warped, or overturned, but metamorphic rocks can be altered sedimentary or igneous rocks.
Are sedimetary rocks formed from heat and pressure?
Sedimentary rocks are formed from buildup of sediment, or particles of dirt and organic debris and things like that. Think of sedimentary rocks like the bottom of a river bed- stuff builds up on top until it becomes hard and solid- a rock, so pressure is a factor, but not necessarily heat. It is usually metamorphic rocks that involve both heat and pressure.
Which location would most likely produce sedimentary rocks a dried-up lake bed of the side of a volcano?
A dried-up lake bed will more likely produce sedimentary rocks than the side of a volcano. Igneous rocks are formed in places near volcanoes.
Sedimentary rocks can't be dated?
Sedimentary rocks cannot be given an absolute date by radiometric testing, but they can be given an estimated date from a few geological laws, for example if a bed of desert sandstone ins under a bed of limestone there is a law that says that the sandstone is older.
What a river causes by removing rocks and soil from itys river bed?
erosion. and due to that erosion we get sedimentary rock.
When sea animals die they fell to the sea bed and buried what did they turn into?
Do You Know The Sedimentary Rocks?They are formed into sediment on the sea floorsediment is sand
What is sedimentry?
Well, sedimentary 'rocks' are made when small parts of eroded rocks are carried by rivers and deposited to the bottom of a river/sea bed. Over time, the pressure of the sea pushes the rocks deeper down, forming a layer of 'Sedimentary' rocks. Miners collect this rock to make other types of rock materials like limestone and sandstone.
Why are fossils found in sedimenta rocks but no in igneous or metamorphic rock?
there arnt any rocks in metamorphic because they would be destroyed by whatver made the rock, the igneous rock is made from lava/magma when it hardens so any fossil structure would burn or disintegrate before the rock even solidified, the sedimentary rock is covered by more layers of dust or dirt or rock after the remains (fossil)is there many times the remains dont survive becoming fossils even sedimentary rock because of the pressure or erosion.
What are the links between metamorphic and igneous and sedimentary rocks?
They are all linked because you have to go through a cycle to get each one. Each one comes from the other.
What does sediment form into when it falls to the sea bed?
when sediment falls into the sea it forms into sedimentary rock which then turns into metamorphic rock and back again it comes from the volcanoes it plays a major role in the rock cycle
