Width of hooch (m)

Answers

According to the graph, the difference between the width of the beach in the years 2010 and 2015 is that in 2015 the variation was 16m while in 2010 it was 5m.

What is seen in the graph?

The graph shows the variation in the width of the beach according to its distance in the years 2010 and 2015.

In the year 2010 the width of the beach has very little variation because it goes from 20m at the distance 0 to 25m at the distance 1000m, so its variation is barely 5 meters.

On the other hand, in 2015 the width of the beach varies to a greater extent because at distance 0 it is 15m wide and at distance 1000 it is 31m wide.

According to the above, the width of the beach has greater variation in 2015 because it has 16 meters of variation, while in 2010 it has only 5 meters of variation.

Hill station located in the alps in western Austria is called Tyrol.

What is Hill station?

A town known as a hill station is one that is situated higher up than the neighboring plain or valley.

For towns established by European colonialists as escapes from the summer heat, the term "hill station" was most commonly used in colonial Asia, though it was also used in Africa.

Dale Kennedy notes that in the Indian context, "the hill station was seen as an exclusive British preserve: here it was possible to render the Indian into an outsider."

The majority of hill stations in India, which has the most of them, are located at an elevation of between 1,000 and 2,500 meters.

High refuge, high refuge to hill station, and hill station to town are the three stages Kennedy, following Monika Beuerlein, believes the development of hill stations in India went through.
