Lava is pouring out of the crust at a vent on the ocean floor. as it cools, igneous rocks form. which characteristics would one expect to find when studying the cooled lava? a. small crystals and coarse texture b. small crystals and fine texture c. large crystals and coarse texture d. large crystals and fine texture

b. small crystals and fine texture

Explanation:

Generally, igneous rocks are formed from the solidification of molten magma . Molten magma are usually semi liquid that originates from the interior of the earth. The location or environment where the magma solidifies determine the kind of igneous rock that is formed.  If the magma solidifies below the earth crust it will result to an intrusive igneous rock which have a coarse texture due to the slow rate of solidification. But if magma creeps or erupt to the surface of the earth crust as lava, the solidification process becomes rapid to form an extrusive igneous rock.

Lava pouring out of the crust at a vent or fissure on the ocean floor are more expose to cooler temperature, water and air . This result to rapid cooling and more faster crystallizing process to form more fine grain and small crystals.  Example of this extrusive types of igneous rocks is Basalt.

The picture below are examples of extrusive igneous rocks . Notice their small crystal . 

figureit out

explanation:

because scientists need to know the stars so they understand space

i do believe that its called,(the segovia highlands); plz check first good luck;
