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 correct answer is B. False
Explanation:
Russia is considered the largest country in the world, located in both Asia and Europe. In terms of population, most of the Russian population is now located in the western zone of the country or in Europe, which includes cities such as Moscow or St. Petersburg. Despite this, since the 19th century and especially during the Soviet Union period there were migrations of Russians eastward or towards the Pacific coastal zone, which led to the creation of Russian settlements in new zones.
However, in the last decades, this migration pattern has decreased and settlements in the east are still small in comparison to those of the west. In this context, the eastward migration has not been a huge phenomenon since 1991, and even if there is still migration and the government promotes this, it has not led to a lack of accommodations or restrictions, which makes the statement false.
D. Rock type
Explanation:
The major factor that influences the strength of rocks is the rock type.
Different rock types are known to have their own relative strength.
Based on their strength, rocks are classified into hard and soft rocks.
Soft rock types are dominated by sedimentary rock. Sedimentary rocks are formed by accumulation and deposition of sediments. They are often layered.
Metamorphic and igneous rocks are usually classified as hard rocks. These rocks forms under very high temperature and pressure conditions.
In engineering applications, the soft rocks not desired for construction purposes although they have their own unique material functions.
Hard rocks are used for heavy duty and durable constructions like dams and bridges.
