Answer: True
Explanation: Jetties are structures constructed perpendicular to shore. They form a 90 degree angle to the shore and cause sediment to accumulate on the updrift side. This is the side that provides sediments.
Jetties are made of heaps of stones or concrete deposited at coastal inlets. They change the longshore current, and due to this, create updrift beaches.
Shoreline Structures such as jetties, and seawells help protect the shoreline from erosion and lessen the effect of currents and waves on the shoreline.
The Mongols set up a tribute empire called The Golden Horde. Serfdom arose as peasants gave up their lands to the aristocracy in exchange for protection from the Mongols. Moscow benefited financially by acting as a tribute collector for the Mongols. Mongol rule kept Russia culturally isolated from Western European trends such as the Renaissance.
Answer:
Deep ocean currents.
Explanation:
In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.
