Why are fences put along some beaches ?
kvv77 [185]

The answer is; B

Sometimes winds carry the sand of the beaches causing erosion. The fences act as breakers of this wind erosion. As wind tries to carry the sand, they encounter the fence and 'break'. Therefore, the sand is deposited along the fence forming a sand dune. These dunes also form protection from storm surges.

What system consists of the region where life exsists and extends from the depths of the oceans to the summit of the mountains?
kodGreya [7K]
The biosphere (from Greek βίος bíos "life" and σφαῖρα sphaira "sphere") also known as the ecosphere (from Greek οἶκος oîkos"environment" and σφαῖρα), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system (apart from solar and cosmic radiation and heat from the interior of the Earth), and largely self-regulating.[1] By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, geosphere, hydrosphere, and atmosphere. The biosphere is postulated to have evolved, beginning with a process of biopoiesis (life created naturally from non-living matter, such as simple organic compounds) or biogenesis (life created from living matter), at least some 3.5 billion years ago.[2][3]

In a general sense, biospheres are any closed, self-regulating systems containing ecosystems. This includes artificial biospheres such as Biosphere 2 and BIOS-3, and potentially ones on other planets or moons.

Why do chicken eggs grow larger compared to other eggs?
Aloiza [94]

Answer:

Chicken eggs grow larger compared to other eggs due to their relative body sizes.

Explanation:

Egg laying and the size of an egg is relative to the size of the organism. So an ostrich lays a really large egg because it is a larger animal and can handle that size. Whereas a bluebird lays a small egg because it is a small bird.
