What's one indirect consequence of building seawalls?

a. it rises the sea level, which infiltrates groundwater aquifers.
b. it causes an excess amount of fertilizer to become stuck in the sand.
c. it increases the frequency of algal blooms.
d. the shoreline habitat is destroyed through loss of sand.

The correct answer would be option D.

Explanation:

Sea walls are the structures or the boundaries that are built near the seashore to stops the erosion in coastline due to the waves that damage the shoreline region.

These structures are built of concrete as the main component and are generally very massive as their primary function is to restrict the effect of wave action. The negative consequence related to the building seawall is that it causes a disturbance in the habitat of the shoreline animals.

Thus, the correct answer is option D.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
