1. Nearly 1/5 of the entire ocean floor has been discovered.
2. it is important that we map our ocean floors so that we understand more about our earth. Learning more about our earth can give us more information about life in the past.
Hope this helps :)
Answer:
By constructing dams they create wetlands -- lush environments which attract fish, ducks, frogs and other creatures. However, beavers can become a big headache for farmers and landowners.
The beavers first gnaw away at the barks of trees and branches near the river or stream to allow them to fall on the flowing water-body, blocking its flow and creating a diversion. They then place twigs, stones, leaves, branches, grasses, uprooted plants and anything else the beaver manages to find, on top of the base to build a superstructure. They're usually around five feet tall, a few feet to over 330 feet in length, and the water reservoir resulting from the dam is usually 1.2 to 1.8 meters in depth.
