Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
Why there were no sedimentary rocks when the earth was first formed?
Sedimentary rocks are the result of weathering, and erosion of other rocks within the rock cycle and from the death and deposition of organic material. As the earth did not have an atmosphere as it first began to form, it had no rivers, no weather and no life. Therefore all of the processes required to produce sedimentary rock were absent.
Is it true all rocks contain organic material?
yes it is true
Can Molten rock material from which minerals can crystallize be called magma?
This question is already answered. From previously existing rocks sedimentary rocks, igneous rocks, and metamorphic rocks are all formed.
Why there were only igneous rocks when the earth was first formed?
Sedimentary rocks are the result of weathering, and erosion of other rocks within the rock cycle and from the death and deposition of organic material. As the earth did not have an atmosphere as it first began to form, it had no rivers, no weather and no life. Therefore all of the processes required to produce sedimentary rock were absent. Metamorphic rocks are the result of igneous or sedimentary rocks undergoing heat and pressure which falls short of complete melting. Therefore igneous rocks would have been required to start the process, as minerals were superheated at great pressure within the molten material that comprised the early earth.

Rocks formed by layering of fragmented crust material are what kind of rocks?
Sedimentary rocks.
Are moon rocks radioactive?
No. At least no more than any other rocks. Almost all materials contain some trace of radioactive material.
What material comes from rocks?
china
What is residual parent material?
ROCKS are residual or in_place parent material.The rocks may be..Igneous rocks,Sedimentry rocks and Metamorphic rocks..
What is extrasive rocks?
Extrusive igneous rocks are 'lava' rocks, those that have formed on the surface from molten material.
What is the raw material in which sedimentary rocks are formed?
weathered remains of other rocks
Rocks formed from melted material inside the earth?
Intrusive igneous rocks.
