Sedimentary rock - Rocks made of sediments like sand, silt, clay, or gravel COMPACTING and CEMENTING together, Metamorphic rock - A rock that forms underground from other rocks due to HEAT and PRESSURE, Igneous Rock - A rock that forms from magma or lava COOLING and SOLIDIFYING into rock, Sediments - Broken bits of rock like sand, silt, clay, and gravel, Magma - Melted rock below Earth's surface, Lava - Melted rock on Earth's surface, Weathering - When rocks are broken into smaller pieces either by chemical or physical means, Erosion - When broken bits of rock (sediments) are moved by wind, water, glaciers, or gravity, Deposition - When sediments are put down somewhere, Compaction and cementation - When sediments are squished into rock and chemicals help make the sediments stick together. Forms sedimentary rock., Heat and pressure - When rocks inside the Earth heat up from heat inside the Earth and feel pressure from the layers above them. This makes metamorphic rock., Melting - When rocks turn into magma or lava, Solidifying - When magma or lava cool and harden into igneous rock, Heat energy - Heat energy in the rock cycle comes from inside the Earth , Characteristics of sedimentary rocks - Fossils, sand or pebbles, Characteristics of metamorphic rocks - Crystals, ribbonlike layers, Characteristics of igneous rocks - Glassy surface, gas bubbles, sometimes crystals,
