The work of a lifeguard<span> is is to rescue and to ensure the safety of swimmers, surfers, and other water sports participants such as in a swimming pool, water park, or beach. To be a certified lifeguard, you must understand the following:
1. D</span><span>eveloping evacuation plans </span><span>
2. </span><span>Florida-friendly beaches
3. S</span><span>aving people caught in rip currents
4. Identifying signs of oncoming tsunamis</span>
The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone.
This is evidenced by Doppler
shift effect. This is the phenomenon where waves that are coming from an object
that is accelerating towards your direction are heard at a higher frequency than that of
objects moving away from you. This is the same for light (which also has
wave-like properties). When observing distant galaxies, astronomers discovered that
they all showed to be redshift (change in the frequency of light towards red
color). This means that all galaxies are moving away from each other because
the universe is expanding.
If you can be more specific on what I am supposed to do I will help.
