What are Sedimentary Rocks?

• Sedimentary rocks are rocks that are made from tiny pieces of other rocks, minerals, and even plant and animal remains.
• These tiny pieces come together and get pressed down over a long time, often in layers.
• Sedimentary rocks often have interesting patterns and are softer than other types of rocks.

Examples:

• Sandstone is a sedimentary rock made from tiny grains of sand that have stuck together.
• Limestone is another type, which forms from tiny shells and bones that piled up on the ocean floor.
• Shale is a sedimentary rock made from mud that gets pressed down over time and turns into layers.

Fun Fact: Some sedimentary rocks can hold important information about the history of the Earth, like fossils of ancient plants and animals!
