Chalk is formed from layers of compressed marine organisms, primarily calcium carbonate derived from the shells of plankton. These layers build up over millions of years in a process called sedimentation.
Chalk is a natural material composed primarily of calcium carbonate, which is formed from the remains of marine organisms over millions of years. It occurs in sedimentary rock layers and is often found in chalk cliffs. While synthetic chalk exists, such as that used for chalkboards or sports, traditional chalk is derived from natural geological processes.
Chalk is a rock that can go onto your hands but can rub off easily chalk i think has a lot of layers it is a sedimentary rock if you hadnt of known that is because well i do not really no ! ha ha ha very funny
One common method to separate sand and chalk is to use the method of sedimentation. By placing the mixture in water, the chalk will float while the sand will sink to the bottom. The layers can then be separated using filtration.
Chalk is made up of tiny calcium carbonate skeletons of marine organisms like plankton. When these organisms die and settle at the bottom of the ocean, their skeletons accumulate over time and create thick layers of chalk. As the soft parts of these organisms decay, their hard skeletons become preserved as fossils within the chalk.
The White Cliffs of Dover are composed mainly of chalk, a soft, white, fine-grained form of limestone formed from the remains of microscopic marine organisms. Chalk is known for its high calcium carbonate content and its characteristic white color, making it a prominent feature of the cliffs. Over millions of years, layers of chalk built up and were uplifted to form the iconic cliffs seen today.
Sedimentary rock, such as limestone, chalk, slate and sandstone.

They are sedimentary rock. Four examples being chalk, sandstone, limestone and slate.
To preserve your chalk artwork for a longer time, use a spray fixative specifically made for chalk. Apply the fixative in thin, even layers over your artwork to protect it from smudging and fading. Make sure to follow the instructions on the fixative product for best results.

To ensure the longevity of your chalk pastel artwork, you can use a fixative spray. This spray helps to seal and protect the delicate chalk pastel colors from smudging or fading over time. Apply the fixative in thin, even layers to preserve your artwork for years to come.
The white cliffs of Dover are mostly chalk (white calcium carbonate) with some small layers of black flint.
