Answer:
Igneous rocks are the cooling and hardening of magma or lava and sedimentary rock is made of sediment cemented together
Explanation:
The three types of rock are igneous, metamorphic and sedimentary. Igneous rock is formed by the cooling and hardening of magma and lava. Examples include granite and basalt. Metamorphic rock is formed when other rocks are exposed to high heat and pressure, causing a chemical change in the rock. Examples include marble and gneiss. Sedimentary rock is formed when sediment is cemented together by minerals. Examples include sandstone and limestone.
