They are made of lighter elements, they tend to be more buoyant than mafic rocks, which are rocks high in magnesium and iron, like basalt.
THE ANSWER IS LETTER D
= Today scientists are devising ways to use advancements in positive ways for the environment.
Answer:
Earthquakes are usually caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake.This is also because the rocks are still pushing against each other, but not moving. After a while, the rocks break because of all the pressure that's built up.

It's C. Mangroves. This is true because The roots of mangroves help absorb the action from waves and help prevent shoreline erosion. When these trees and shrubs are removed, additional support structures such as seawalls are needed. Along the same lines, seagrass stabilize sediments on the seafloor.There are 80 described species of mangroves, 60 of which live exclusively on coasts between the high- and low-tide lines. Mangroves once covered three-quarters of the world's tropical coastlines, with Southeast Asia hosting the greatest diversity. Only 12 species live in the Americas. Mangroves range in size from small bushes to the 60-meter giants found in Ecuador. Within a given mangrove forest, different species occupy distinct niches. Those that can handle tidal soakings grow in the open sea, in sheltered bays, and on fringe islands. Trees adapted to drier, saltier soil can be found farther from the shoreline. Some mangroves flourish along riverbanks far inland, as long as the freshwater current is met by ocean tides. Hope this helps!
