Answer:
A. It helped sailors steer around rocky coasts.
Explanation:
An astrolabe is an elaborate inclinometer. An inclinometer is an instrument used for angles of slope, elevation, or depression with respect to gravity's direction. It is also used as a tilt sensor, tilt indicator, slope meter, slope gauge.
<em>A. It helped sailors steer around rocky coasts.</em>
Rocky coasts are dangerous. In order to maneuver them, the sailors used an astrolabe. This helped them to understand the angles of slopes, elevation, depression of several rocks on sea.
<em>B. It aided navigators in predicting the weather.</em>
An astrolabe cannot predict the weather.
<em>C. It allowed sailors to know their north-south location.</em>
A compass is used for this purpose.
<em>D. It kept crews from getting sick.</em>
An astrolabe is not a medicinal equipment.
The salinity can simple be defined as the amount of salt that is contained in the ocean waters.
The salinity of the ocean waters comes from the interaction of the chlorine and the sodium which are in abundance. With their interaction the salt is created, or chemically, the NaCl.
The salinity varies from place to place, and it is dependent on multiple factors, with the climate being the most important, backed by the income of freshwater from rivers and streams.
The hotter it is, the higher the salinity, because there's bigger evaporation and the salt concentrates more, and vice versa.
The waters that are near a coast, and there's a stream or a river that constantly bring in freshwater, are less saline, because the freshwater increases the amount of water on the amount of salt, thus it is much more dispersed.
Answer:
also learned how plate tectonics is important in the formation of rock, mountains, volcanoes and earthquakes. Studying the interior of the Earth helps learn about all of these and the processes that helped create the Earth and currently drive plate tectonics.
False, I know that because humans dont eat dog food in summer months.
