Chalk is a type of sedimentary rock that primarily consists of the mineral calcite, derived from the microscopic remains of marine organisms, such as coccolithophores. These tiny planktonic algae accumulate on the ocean floor after death, forming thick layers of calcareous ooze. Over time, pressure from overlying sediments compacts and lithifies this material into solid rock. Chalk typically forms in warm, shallow marine environments where these organisms thrive.
What else can I help you with?
Is chalk a type of igneous rock?
limestone or could be gypsum Could be chalk. Dip it in vinegar. If it fizzes, it might be a sedimentary carbonate rock like limestone or chalk. There is always a possibility it is another kind of sedimentary rock or possibly an extrusive igneous one. Testing is needed to be sure.

Is caulk a Sedimentary rock?
No limestone and sandstone are sedimentary rocks. Chalk is not.
Is chalk an extrusive rock?
No, chalk is not an extrusive rock; it is a type of sedimentary rock. Chalk is primarily composed of calcite, derived from the accumulated remains of microscopic marine organisms. Unlike extrusive rocks, which form from lava that cools quickly at the Earth's surface, chalk forms through the accumulation and compaction of sediments over time.
Chalk is an example of what kind of rock?
Chalk is a form of limestone, a sedimentary rock.
Where does sedimentary rock chalk form?
they come from the sky
Chalk and coal are examples of a kind of sedimentary rock called?
Chalk and coal are examples of a kind of sedimentary rock called biochemical sedimentary rock. Biochemical sedimentary rocks form from the accumulation and lithification of organic remains, such as shells and plant material.
What can sedimentary rocks make?
sedimentary rock can form rock such as sandstone that the Egyptian pyramids were built of or they can form the chalk that is used to write on the ground or on a black board.
