Question

Rainfall on a map is shown by
A. Isohyets
B. Isobars
C. Isotherm
D. None of these

Answer 1

Hint: Rainfall on a map is shown by lines joining points of equal rainfall. It is derived from the Greek word “hyein” which implies “rain”. ”Iso” implies “equal” or “same”.

Complete Answer:
Let us look at the options and discuss the solution.
Option A. An isohyet is otherwise called an isohyetal line, and it is a line on a guide that associates focus that has similar measures of precipitation in a given period or for a specific tempest. The technique utilized in assessing normal precipitation over a specific region is known as an isohyetal strategy. Thus, it is the correct option.

Option B. Isobars are lines on a climate map consolidating spots of equivalent air pressure. The numbers measure the air pressure in millibars. Thus, it is an incorrect option.

Option C. Isotherm is a line that is drawn on a guide or outline getting focused together with a similar temperature. Isotherms are usually utilized in meteorology to show the appropriation of temperature at the Earth's surface or on a diagram demonstrating a steady level or consistent weight. Thus, it is an incorrect option.

Hence the correct answer is Option A.

Additional Information:
An isohyetal strategy utilizes geographical information along with other information to think of bona fide gauges. The strategy considers the plotting of precipitation esteems on an appropriate base map at their stations.

Note: Isohyets are used to make an isohyetal map.
-Isohyetal lines are essentially founded on insertion between rainfall measure stations.
-When isohyets are being made, it is theorized that precipitation between two distinct stations varies directly except if there is a fast or brief change in geology that shows the inverse.
