Explanation:
The petals on a flower are not just to be pretty, they attract insects (bees) that will pollinate another flower or that flower, so it will reproduce.
The mangroves trees help in holding the soil in place, they help in absorbing the energy of waves, and they help in filtering water and better the quality of it.
Mangroves are a kind of estuarine or coastal wetland, featured by the existence of salt amended shrubs and trees, which develops beside the coast in subtropical or tropical latitudes all around the world. Several of the mangroves forests can be determined by their dense tangle of prop roots, which make the trees seem to be standing on stilts above the water.
The mangroves safeguard the shorelines from destructing hurricane, storms, winds, and floods. They help in inhibiting erosion by stabilizing the sediments with their tangled root infrastructure. They sustain the clarity and quality of water, trapping the sediments and filtering pollutants arising from land.
The oldest oceanic crust is found at the mid-ocean ridges. Thus, option "A" is correct.
<h3>How old is the youngest oceanic crust?</h3>
The ocean crust is about younger than 200 million years (for example, smaller than 5% of the age of the earth).
The crust is most naive (still being created by volcanic eruptions) along the axis of the mid-ocean ridges and increases in age down the sides of the mid-ocean rises and out onto the more serious basin floors.
Thus, option "A" is correct.
