According to the rock cycle, which of the following transitions are
possible? mark all that apply. you may choose more than 1.
a metamorphic rock becomes an extrusive igneous rock after it melts and
moves to the surface.
magma turns into sedimentary rock due to heat and pressure.
a sedimentary rock becomes soil due to weathering.
magma crystallizes to become sedimentary rock.
igneous rock turns into metamorphic rock after exposure to wind, water and
ice.

I think that the answer will be The rock cycle best explained as the relationship between earth’s internal and external processes.  Weathering (breaking down rock) and erosion (transporting rock material) at or near the earth's surface breaks down rocks into small and smaller pieces.  These smaller pieces of rock (such as sand, silt, or mud) can be deposited as sediments that, after hardening, or lithifying, become sedimentary rocks. Extreme pressure from burial, increasing temperature at depth, and a lot of time, can alter any rock type to form a metamorphic rock.   If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock. Metamorphic rocks can form from either sedimentary or igneous rocks. The sedimentary particles from which a sedimentary rock is formed can be derived from a metamorphic, an igneous, or another sedimentary rock. All three rock types can be melted to form a magma. Thus, the cycle has continued over the ages, constantly forming new rocks, breaking those down in various ways, and forming still younger rocks.  Rocks at the surface of the earth range in age from over three billion years old to a few hundred years old.  

Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.

Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly.

i would say it is a and b.

hope this
