redshift and doppler effect
redshift is an increase in the wavelength of radiation emitted by a receding celestial object as a consequence of the Doppler effect and the Doppler effect is a tool used to measure frequency changes as light travels to, from, or pass an observer
The hardness of the water is given by the presence of calcium and magnesium <span>carbonates. The mixing of these minerals in water turns the water more alkaline.
</span><span>The Langelier saturation index uses the pH to predict the calcium carbonate stability of water. So, through the pH, it is possible to know whether a water is more or less acidic.</span>
Nile river is the longest river in Africa
Indirect effects include pluvial lakes, changes in sea level, and isostatic depression.
<u>Answer:</u>
A "geographer" who works with "city governments" to help layout new parks and streets might be a cartographer.
<u>Explanation:</u>
- A cartographer is the one who is responsible for making precise and accurate maps of different places by studying the features and the orientation of "natural and man-made objects" at that particular place.
- To prepare layouts of new parks and streets already built or to be built in the city, the city government would hence need to consult a cartographer.
