Q

A rock and sand structure extending from the bank of the river toward the channel is known as a __________.

🔍 Key Concepts

• River training structures used to control current and protect banks • How rocks and sand are used to build projections from a bank into the river • Differences between features that extend from shore and those that are islands or cuts in a bend

💭 Think About

• Which option describes something that physically STICKS OUT from the riverbank toward the main channel to influence current or protect the bank? • Which option sounds more like an island or bar in the river, rather than a man‑made structure tied to the bank? • Which option refers to changing the course of a river bend rather than building out from the bank?

✅ Before You Answer

• Identify which terms are artificial river structures vs. natural formations • Check which choice clearly extends from shore toward the channel, not parallel to it or detached from it • Eliminate any terms that describe islands, sandbars, or channel shortcuts rather than built structures
