Answer:

Sand dunes are geological features that are commonly formed in the areas where there is abundant concentration of sands. This includes the bars in the rivers, deserts, and coastal beaches. The agent that is responsible for dune formation is wind. The sand size particles due to high wind get eroded from different places and transported to a place where the accumulation of sand is more.

It is a pile of sand and it has two sides, namely the wind-ward side, the direction from where the wind blows and the flip side, where there are no wind and sand grains deposited.

The stovepipe dunes in California have formed in this way.

dimulka [17.4K]

Answer:

Sr is the more metallic element

Bi is the more metallic element

O is the more metallic element

As is the more metallic element

Hence, as we move across the period, elements become less metallic. As we move down the group elements become more metallic.

This is the basis upon which decisions were made about the metallic character of each of the elements listed above.
