Why are magma and lava not considered to be rocks ?
a both are formed by weathering and erosion
b neither is solid
c gravitational or potential gravitational energy
d all of these power the rock cycle

B. Neither is solid

Explanation:

The magma and the lava are not considered as rocks because they are not in solid aggregate condition. Both of them are liquid, though very dense liquids, made out of molten rocks, metals, and very often trapped gases. Even though they are not considered as rocks, they are the ones that are responsible for the formation of the rocks. As the magma cools off inside the crust, or the magma on the surface, they consolidate, become solid, and form igneous rocks, intrusive or extrusive. These rocks later give the basis for the formation of the two other types of rocks, the metamorphic and the sedimentary, depending on the conditions. Eventually, those rocks will be subducted, melted into the mantle, recycled, and will come out as magma or lava toward the surface again in the distant future.
