Answer:
Using a control group means that any change in the dependent variable can be attributed to the independent variable.
Explanation:
The barrier islands shelter and protect the mainland from the powerful forces of wind, waves, tides, currents and the ravages of storms and hurricanes. They shelter the estuaries that form behind the barriers.
Barrier islands form as waves repeatedly deposit sediment parallel to the shoreline. As wind and waves shift in keeping with weather styles and neighborhood geographic features, those islands constantly pass, erode, and grow. They can even disappear entirely.
Key Biscayne is a barrier island found at the bottom give up of a sequence of islands that stretches alongside the southeastern coast of Florida. Barrier islands are construct-united states of sand that shape alongside the coast of larger land bodies.
Barrier islands are critically crucial in mitigating ocean swells and different hurricane events for the water systems at the mainland aspect of the barrier island, in addition to defensive the coastline. This efficaciously creates a unique environment of exceedingly low strength, brackish water.

Answer:
Rays of light emanate from a real image, but only appear to do so from a virtual image.
Explanation:
- The real images are inverted to the object and rays of light are emitted from the virtual object tends to do so and this image is always bigger than the object.
- Thus a real image occurs where the rays of light converge and a virtual Image occurs when the rays of light diverge and a virtual image can't be projected to a screen as compared to a real image.

The Richter scale is used, from 0.1 to 9.0 magnitude. The Richter scale is determined from the logarithm of the amplitude of waves recorded by seismographs.
