Microscopic plants called algae grow inside the top layer of sea ice in the Antarctic if enough sunlight reaches that layer of ice and enough seawater, which contains nutrients, reaches that layer after splashing onto the surface. Even though moderate snow cover reduces the sunlight that filters into the top layer, sea ice with moderate snow cover typically contains even more algae in the top layer than does sea ice with less snow cover.

Which of the following , if true most helps to explain the apparent discrepancy?

(A) As the weight of accumulated snow forces ice lower in the water, more seawater splashes onto the surface and seeps through the snow.

(B) Seawater in the Antarctic often contains higher concentrations of nutrients than does seawater in more temperate regions.

(C) As the air temperature around sea ice decreases during the winter, the likelihood decreases that snow will fall and thus add to any existing snow cover.

(D) The nutrients on which algae rely are common in seawater throughout the Antarctic.

(E) More sunlight filters through a layer of ice than through an equally thick layer of snow.

Based on the information given, the option that helps to explain the apparent discrepancy is A. As the weight of accumulated snow forces ice lower in the water, more seawater splashes onto the surface and seeps through the snow.

Based on the information given, it was written that although moderate snow cover reduces the sunlight that filters into the top layer, sea ice with moderate snow cover typically contains even more algae in the top layer than does sea ice with less snow cover.

The reason for this is because as the weight of accumulated snow forces ice lower in the water, more seawater splashes onto the surface and seeps through the snow. This helps in opening up the possiblity of higher growth in algae under the high snow cover.

The correct answer is: (A).

Explanation:

glacial erosion, the picking up and movement of earth beneath a glacier, is also referred to as plucking. erosion and transportation of individual pieces of bedrock, especially large "joint block occur as a result of this glacial erosion. plucking is type of erosion in which rocks become frozen into the bottom and sides of the glacier.as the glacier moves downhill it 'plucks' the rocks frozen into the glacier from the ground.
