Watch the video to learn about the Rock Cycle, then complete the questions to review. What is the rock cycle? Earth’s process of changing one type of rock into another type of rock Any process that an object on the Earth goes through, whether plant or mineral The path that magma follows when it changes into lava or igneous rock Any type of rock formation that is circular or triangular in shape How is the rock cycle like recycling? It depends on humans to do most of the work. It takes place on the planet Earth. It transforms existing material into new material. It requires weather and factories for completion. What helps to change rocks into other types of rocks? heat erosion pressure all of the above Layered rock, such as limestone, is an example of what kind of rock? melted rock sedimentary rock igneous rock metamorphic rock Read about the "Rock Cycle" and then answer the questions.-click here to read the passage- According to the passage, what type of rock do most rocks start out as? igneous metamorphic sedimentary magma What would be the best title for this passage? Rocks are Fun to Throw How Rocks are Cooled and Hardened The Processes of How Rocks are Formed 5 Main Types of Rocks What is the process that turns a sedimentary rock into a metamorphic rock? Cooling and hardening Compacting and cementation Heat and pressure Heat and melting. According to the passage, what is the rock cycle? The circular path the rock takes How rocks are created from dirt Process of how rocks are formed from dead plants and animals The process that forms and recycles different rocks Watch the video to learn about how fossils are formed, then complete the questions to review. Which of the following can turn into sedimentary rocks as part of fossil formation? Select ALL that apply. mud sand ash To form a fossil, water dissolves bones and leaves behind minerals which become stone mud wood Why are marine fossils like sharks more common than land fossils like dinosaurs? Dinosaurs move faster than sharks, so they're less likely to stay in one place. Animals in the sea have more bones and teeth to be found. Animals in the sea die and sink into the sand and mud at the bottom to be buried quickly. Where are most dinosaur fossils found? Near water, so they end up covered in mud and silt. Near a prairie, where they end up covered in grass Near a forest, where they end up covered in leaves Read about "Types of Fossils" then answer the questions. -click here to read the passage- Which of the following parts of a forest ecosystem could not become a fossil? twigs that dropped from trees a dead mouse a puddle deer footprints in the soil What is the difference between mold and cast fossils? Mold fossils form from collected minerals and cast fossils do not. Mold fossils are impressions into rock and cast fossils form from minerals filling molds. Cast fossils are impressions into rock and mold fossils form from minerals filling casts. Cast fossils are formed in sedimentary rock but mold fossils are not Fossils are typically found in which type of rock? Sedimentary Igneous Metamorphic The preserved remains of ancient living things are called _. fossils rocks bones
