Yes, it's a sedimentary rock composed of calcium carbonate.
Classroom chalk is not necessarily the same as chalk the rock, since it may include binders and pigments in addition to pure calcium carbonate.
Yes. Chalk occurs naturally. It is a form of limestone, or calcium carbonate (CaCO3). Along the British coastline there is a spectacular formation of chalk called The White Cliffs of Dover.

Yes, chalk is a type of organic rock if it is natural. More specifically, it is a type of sedimentary rock made from a variety of limestone.
Chalk is an organic sedimentary rock made of tiny shells and shell fragments.
Chalk contains organic material. It is made out of microscopic shells of phytoplankton and may contain visible fossils as well.
Chalk is inorganic in nature. It is largely made up of calcium carbonate.
no chalk is a rock but it is not hard
It is clastic
Chalk is a very soft sedimentary rock.
Yes It Is.
because the weather break down the rock until it gets soft like chalk
Chalk is a form of limestone, a sedimentary rock.
Made up of clay and sands. Erodes quicker than hard rock which is limestone or chalk. Not resistant to weathering and erosion. Eroded quicker than hard rock which creates a bay and the hard rock is called a headland. When you have hard rock then soft rock alternating it is called a discordant coastline.
Nature's chalk is limestone--hard. Blackboard chalk is soft--gypsum.
Chalk is a biochemical sedimentary rock.

Chalk is a hard rock, with large lines of weakness so will erode by physical weathering and the sea.
Hard rock, an example of soft rock is Barton-on-sea.
classic rock, alterlative, hard rock, soft rock, To be specific talk kinda like chalk,amethyst nice and sparkly and more!!!
Chalk is a fossil itself and chalk is soft, and so while you might form a fossil; in it, it would not remain. Within chalk there is often harder rock - which sometimes does contain fossils.
No. Chalk is a soft carbonate sedimentary rock whereas slate is a fissile rock with a pronounced cleavage formed by the metamorphism of fine grained sedimentary rocks containing clay minerals. Chalk (the soft white mineral used in marking on a slate or blackboard) is actually now commonly made from gypsum but in the past was actully composed of calcitic chalk.

Chalk is a form of limestone, a sedimentary rock.
Chalk would fit this description.
Chalk - however, the fossils are microfossils called Coccolithophores. Limestone is a soft sedimentary rock, not exactly "crumbly" like chalk but more likely to contain fossils visible to the naked eye.
It's Rock, Chalk, Jayhawk KU!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
