Why is there flint in chalk?
Cryptocrystalline quartz concretions (flint) of different density, size, morphology and abundance, occur isolated and concentrated in layers in the Late Cretaceous (Tuffaceous) Chalk of NW Europe. Concretions started to grow during early diagenesis at sites of elevated authigenic silica-polymorph concentrations, a result of bacterial metabolism in an anoxic mixture of skeletal carbonate, skeletal opal, organic matter and pore fluid. The late diagenetic growth of flint nodules has been investigated with the help of a numerical model that simulates the dissolution, diffusion and precipitation of different silica polymorphs in a medium of changing porosity/permeability. It is suggested that the occurrence of various flint types reflects the distribution of the early diagenetic, authigenic silica polymorphs, rather than the distribution of detrital skeletal opal. The model results imply that flint nodules can be used to reconstruct the depositional and early diagenetic conditions during the genesis of sequences of Chalk with flint.
How does a chromosome control cell processes?
A chromosome controls cell processes by biological processes such as mitosis and meiosis. These cell processes are what direct cell processes such as cell growth and division.
When scientists study natural processes they use to state observations about the processes and they use to state how or why the processes occur?
descriptions; explanation
What processes are involved in the water cycle?
The processes involved in water cycle are: Evaporation, Condensation, Precipitation and Collection. These are the important processes that are involved.

What are eogenesis telogenesis and mesogenesis?
Eogenesis: early diagenetic eventMesogenesis: middle diagenetic events Telogenesis: late diagenetic events
What has the author Michael Alexander Sweeney written?

Briefly describe classification of manufacturing process?
The different classifications for manufacturing processes are casting processes, machining processes, surface finishing processes, metal working processes joining processes, and shearing and forming processes. The processes used to change the physical characteristics of materials are hardening and tempering.
What are the different geological forces that shape the earth?
There are seven main geological forces that shape the planet Earth. These forces are Aeolian processes, biological processes, fluvial processes, glacial processes, hill slope processes, igneous processes, and tectonic processes.
What has the author Stanley Turner Paxton written?
Stanley Turner Paxton has written: 'Petrography and diagenetic evolution of cements in some Pleistocene glaciofluvial deposits from southwestern Ohio, southeastern Indiana, and northern Kentucky' -- subject(s): Glacial epoch, Cementation (Petrology)

What is the definition of external processes?
processes which bring about changes on the surface of the earth are called external processes.
