Which type of rock has a coarse texture due to slow cooling in magma chambers?
extrusive
intrusive
metamorphic
sedimentary

Extrusive rocks

Explanation:

Extrusive rocks are developed from the crystallization of liquid (Molten rock).The texture of the extrusive rocks depends upon the measure of cooling of the melt. Passive cooling allows large crystals to be formed.The slowing cooling of Magma and the resultant Plutonic rock bodies cool and crystallize slowly forming coarse-grained texture.These coarse grained-texture varieties are called Phaneritic where the mineral grains can be seen large without a magnifying glass.These extrusive rocks are also named as volcanic rocks.
