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.
Answer:
People in some temperate zones may benefit from milder winters, more abundant rainfall, and expanding crop production zones. But people in other areas will suffer from increased heat waves, coastal erosion, rising sea level, more erratic rainfall, and droughts .
Answer:
D .physical processes observed today (such as erosion and volcanic eruption) occurred much more rapidly in the past, quickly sculpting the Earth’s surface.
Explanation:
physical processes observed today (such as erosion and volcanic eruption) have been active in the past and are responsible for the geologic history we see preserved in the rock record.
Uniformitarianism, in geology, the doctrine suggesting that Earth's geologic processes acted in the same manner and with essentially the same intensity in the past as they do in the present and that such uniformity is sufficient to account for all geologic change.
The Principle of Uniformitarianism states that the laws of nature that are in effect today, have been in effect forever. The major folds and unconformities seen in rocks could not have been produced in such a short time if the principle of uniformitarianism is applied.
