Question

Melting ice sheets increase the volume of water in the oceans and reduce the salinity of water. How would this affect:

a) sea animals in polar regions?
b) coastal areas already at sea level?

Answer 1

Melting ice sheets contribute to global sea level rise and reduced salinity, affecting sea animals in polar regions by disrupting food sources and breeding patterns, while coastal areas at sea level face inundation and potential habitat loss.

Step-by-step explanation:

Melting ice sheets due to global warming have significant impacts on both sea animals in polar regions and coastal areas at sea level.

Sea animals in polar regions may experience adverse effects due to lower salinity levels and changes in their habitat's temperature. These changes can affect the availability of their food sources and may interrupt breeding patterns. Specifically, species adapted to higher salinity and colder waters may struggle to survive in the altered conditions.

For coastal areas already at sea level, the increased volume of water resulting from ice melt leads to sea level rise. This phenomenon can inundate shorelines, reduce island sizes, and potentially submerge some islands entirely, leading to loss of habitat for species and threatening human communities living in these areas.

The combination of meltwater from glaciers and the expansion of water as it warms contributes significantly to rising sea levels. Global sea level is expected to continue rising, exacerbating these problems and posing challenges for preservation of biodiversity and coastal management.

Answer 2

Answer:your answer is B

Step-by-step explanation:

In the polar regions if the water goes onto shore it would freeze adding to the icy land and giving sea animals an advantage as all the sea animals would be at the to of the sea level giving a better attack on prey. as in Coastal area it would flood the area causing and flood.
