Correct answer is False.
Explanation:
Cambrian explosion refers to period of geological history of our planet in which most of the multicellular organisms appeared in fossil layers. That was some 540 million years ago.
This period indicates that multicellular organisms began to develope in the early Paleozoic era. Before that much of the living organisms were singlecellular. Cambrian is the first period of Paleozoic era and it lasted between 540 and 485 million years ago. It is followed by Ordovician Period.
The bottom line is that Cambrian explosion is related with 'great occurrence of new and developed species'.

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.
