They are different because lava is when it hits earth's atmosphere; magma turns to lava. Magma is when its inside the volcano. They are different because of the color: darker/blacker and magma rocks are way hotter. Lava rocks are colder and fragile.

Rocks that form as a result of cooling magma?
Rocks formed from magma are igneous rocks. Extrusive igneous rocks form from lava at or near the surface. Intrusive rocks form from magma below the surface.
How do igneous rocks that form from cooling lava differ from igneous rocks that form from cooling magma?
The difference between the two lies in the mineral crystal size. Rocks that form from lava on the surface will cool quickly, with little time for crystal formation. Rocks that form from magma below the surface will cool slowly, resulting in larger mineral crystals. Chemically, they could be identical.
Why does lava cool into?
The minerals in magma form crystals when solidifying, giving igneous rocks their characteristic hardness.
Where is igneous rock formed?
Igneous rock is formed when hot magma from inside the earth meets the earth's outer crust and eventually cools to form one of the three different types of rock.
What type of rocks form from melting and cooling?
These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.
What materials do rocks form from?
Magma or Lava
What is a large group of rocks which form magma or lava?
Igneous rocks.

Are magma and lava sedimentary rocks?
No. Magma and lava are molten rock. When the cool they form igneous rock.
How do igenous rocks form?
They form when magma or lava cools and solidifies.

How do igneous rocks form?
Igneous rock forms from the cooling of molten material called magma or lava.
Lava is magma that has reached the what in an eruption?
Lava is magma that has reached the surface of the earth in an eruption. When this cools down, it will form igneous rocks.
