Lava cools and solidifies because it loses heat to its surroundings, transitioning from a liquid state to a solid state. The atoms and molecules in the lava arrange themselves into a crystalline structure as they cool, forming a solid rock. The specific type of rock that forms depends on the composition of the lava.

Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
What type of rock that forms due to cooling?
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
What rocks come from lava flow?
Lava flows cool to form extrusive igneous rock. Most lava flows consist of basaltic lava, cooling to form a dark rock called basalt. Some, however, may consist of andesite or, rarely, rhyolite and similar lavas.
Is lava a sedimentary rock or igneous?
The common usage of "lava rock" in the USA refers to a black rock with a number of visible bubbles or air pockets that is formed from cooled lava on the surface. Although lava rock is an igneous rock, it is not the same as the definition for the word igneous, which can also include igneous rocks which have solidified from magma below the surface.
How is a blob of lava turned into rock on the sea bed?
When lava flows into the sea, it rapidly cools down and solidifies, forming a type of rock called pillow basalts. This process, known as quenching, allows the lava to solidify quickly, capturing the shape of a pillow as it hardens. Over time, additional layers of lava can accumulate and solidify on top of each other to form a larger rock formation on the sea bed.
What rock form from cooling lava?
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
What rock forms from lava that cools?
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
What happens to lava when it enters the ocean?
On contact with water lava will cool rapidly to form rock.
What type of rock that forms due to cooling?
Lava will cool to form extrusive igneous rock. The exact type would depend on the composition of the lava.
How did the lava cool from hot lava to hard rock?
The minerals in magma form crystals when solidifying, giving igneous rocks their characteristic hardness.

When a volcanoes lava washes into the ocean what rock does it form?
lava rock
What rock is formed when magma and lava cool and harden?
Igneous Rock.
Why is lava and magma not a rock?
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
