True or false: Gravel, cobbles, stones, and boulders are examples of "Rock Fragments."

The statement is true because gravel, cobbles, stones, and boulders are all considered types of rock fragments. Rock fragments refer to pieces of rock that have been broken away from larger rock masses through various geological processes. Each of these materials varies in size, with gravel being smaller pebbles, stones being medium-sized, cobbles being larger, and boulders being the largest. Together, they exemplify the wide range of sizes that rock fragments can take, thus confirming the accuracy of the statement. Understanding the classification of these materials is essential in fields like geology and construction, especially in applications related to drainage and septic systems.
