Answer:
B. Erosion
Explanation:
Igneous rock (derived from the Latin word ignis meaning fire), or magmatic rock, is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
Erosion is the process of wind, water, and ice breaking down rocks tint smaller pieces. Erosion breaks down igneous rocks, metamorphic rocks and sedimentary rocks. Erosion breaks down igneous rocks in the same manner as it breaks down other rocks
