What does non interlocking mean?
Non-interlocking rock texture is a characteristic of clastic sedimentary rock, where particles of sediments have been cemented together by precipitated minerals. The particles may be loosely cemented, with spaces between particles. Rocks of this type tend to be 'soft' in that they are broken easily. An interlocking crystalline rock structure is formed by the progression of crystallization temperatures of various minerals as they form from solidifying magma. The solidification temperatures of the mineral constituents vary, and the last to crystallize is usually quartz, which infills any voids that remain. The resultant mineral structure is compact, hard, and resistant to weathering.
Is metamorphic rock generally soft rock or hard rock?
Comparatively hard, due to larger interlocking crystals and a higher density than most igneous/sedimentary rocks
Why are sedimentary rocks softer than igneous rock?
It's because sedimentary rocks have big air spaces in them which makes them very porous, whereas igneous and metamorphic rocks are less porous, as the crystals are tightly packed.
What rocks are formed when sediments are compressed compacted and cemented togerther?
Sedimentary rocks.
What are interlocking grains?
interlocking grains fit tightly together to make hard rocks
Is igneous harder than sedimentary rocks?
They are generally harder because of their interlocking crystalline structure and mineral composition.
Rocks formed from weathered debris from preexisisting rocks are called?
They are called clastic sedimentary rocks.
Are sedimentary rocks classified tofoliated sedimentary rocks?
Metamorphic rocks are classified by foliation or lack there of, not sedimentary rocks. They are classified into Clastic Sedimentary, and Chemical Sedimentary.

Are sedimentary rocks formed from fragments of other rocks chemical sedimentary rocks?
No. The rocks you describe are clastic or detrital sedimentary rocks.
What has the author Sam Boggs written?
Sam Boggs has written: 'Petrology of sedimentary rocks' -- subject(s): Sedimentary Rocks 'Petrology of sedimentary rocks' -- subject(s): Rocks, Sedimentary, Sedimentary Rocks

Are there any fossils in sedimentary rocks?
Yes all fossils occur in sedimentary rocks or rocks that began as sedimentary rocks.
What rocks are formed when sediments are compressed compacted and cemented togerther?
Sedimentary rocks.
Where are crystalline minerals found?
In all three rock types: igneous, sedimentary, and metamorphic. By definition, a mineral has a crystalline structure, and rocks are composed of combinations of minerals. Rocks with interlocking crystalline mineral structures are usually igneous or metamorphic.
What are interlocking grains?
interlocking grains fit tightly together to make hard rocks
