Louisiana wetlands are worth to be protected. Not only cause they do the wetlands provide a buffer zone from a hurricane storm surge, but also Louisiana wetlands give commercial fishermen with jobs and this wetlands are home to thousands of Mammals and trees or plant, some are protected by the federal government. The loss of all Louisiana wetlands is a growing problem that will continue to grow . Louisiana wetlands play a key role in the protection of the residents of Louisiana. These wetlands need to be protected, and they need to be protected now to save the future of Louisiana. add 50 words

i am confused, what is the question? i can you out if you put it into more depth.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)
