Diatoms.
a coastline made out of chalk! ta daa!
YEP!
no,chalk is not magnetic because it is not made out of either iron or steel or otherwise it is not made out of meatal
Diatoms are microscopic plants (phytoplankton) found in oceans and lakes. Their cell wall is made of Silica which remain after the diatom dies. Diatoms are single celled, photosynthetic algae this means that they are producers!!
I would say diatoms. Diatomaceous earth is chalky, much like the calcite powder from limestone actually used for chalk.
The cell wall of diatoms are very thick and remain long after the diatoms die. when the cell wall remains of many dead diatoms clump together, they form a crumbly, abrasive substance called diatomaceous earth or diatomite.============================================The rock type called Chalk is also made of diatom skeletons.
flamborough is made from chalk because it is
We know that limestone is made up of those things, and some others. We also know that chalk, a kind of limestone, is composed mainly of tiny shells made of a mineral called calcite.

Chalk is mainly made of Calcium Carbonate.
Diatoms belong to the class Bacillariophyceae, which is a class of algae characterized by their unique cell walls made of silica.
Diatoms are a form of algae found almost everywhere. Commonly diatoms refers to the silica exoskeleton left behind when the alga dies. White Cliffs of Dover made from billions of diatom skeletons.
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.
dust from a chalk. Chalk is made from calcium carbonate, CaCO3.
