Answer:
A characteristic of the Woodland and Mississippian cultures was the earthen mounds.
Explanation:
The Woodland and Mississippian cultures were the most advanced cultures in what is now the USA. They had well-developed civilizations in comparison to the people groups in their surroundings. Their trademark though was the construction of earthen mounds that are found all over the territories in which the two cultures existed.
The earthen mounds, as the name suggests, are mounds made out of the ground. They vary in size, from just a few meters to hundreds of meters. Their shapes too vary, with some being in a semi-circular shape, some like bulges, while some even like snakes. The purpose of these mounds is still a theme of hot debate, but it is most commonly thought that they had religious purposes.
Answer:
<em>Coastal Armoring</em>
Explanation:
It is a practice of continuously reshaping the shoreline. It can prevent the shoreline from sandy beaches, wetlands and other intertidal area's. From moving in land and the land get eroded the sea level rises. Since its a complex process the coastal armoring has the potential to remove habits pf marine organisms and also checks the beach generation by restricting the natural movements of sediments. They act to stabilize the shoreline. According to me its a good investment as shoreline erosion may greatly impact human lives, like changes in sea level and high tides and waves or any construction of harbors, etc. Alternative channels for coastal armoring may include the building of fences and wall-like structures, raising the bar for the shoreline.
