Just about all materials contract when they cool. As newly solidifies lava or magma cools and contracts, the stress often creates cracks.
The rocks that are formed from cooling of lava are known as Igneous rocks.
A rock formed from cooling lava is classified as an igneous rock. Igneous rocks are formed from the cooling and solidification of magma/lava. They can be further classified based on their mineral composition, texture, and formation process.

Igneous rock, such as basalt or andesite, results from the cooling of lava from a volcano.
A long crack from which lava flows is called a fissure.

Pumice is the result of extremely fast cooling lava.

Volcanologists, or scientists who study volcanoes, are most likely to study the cooling of lava. They are interested in understanding the behavior, properties, and processes associated with volcanic eruptions, including the cooling and solidification of lava after it is erupted from a volcano. By studying the cooling of lava, volcanologists can gain insights into various volcanic phenomena and hazards.
