QUESTION 3

1. Choose all that apply. Consider a hike from the peak of Mt. Terevaka, to Tongariki on the cost, to the peak of Poike. Which of the following statements are true?

   		It would be a fairly gentle descent to the coast at Tongariki, dropping roughly a ½ kilometer over a horizontal distance of approximately 5 km (~6 degree slope).
   		It would be a fairly steep descent to the coast at Tongariki, dropping roughly a 2 kilometers over a horizontal distance of approximately 5 km (~22 degree slope).
   		The hike from the coast up the extinct volcano Poike would be a fairly steep climb ~300 m over a horizontal distance of roughly 1 km (~17 degree slope).
   		The hike from the coast up the extinct volcano Poike would be a gentle slope up as you would climb ~300 m over a horizontal distance of roughly 5 km (~3 degree slope).

Answer 1

Mt. Terevaka is 507 metres above sea level. So it is about 500m high.

2) Ahu A Tanga is about 14metres above the sea level and is about 2 km away from the peak. so the slope is $\frac{490}{2000}=0.245$ (slope is calculated here, by dividing the total hight by the ariel distance between the places)

Ahu Akahanga is at 5m above water level. and a distance of about 10-11 km away from the Terevaka peak. so the slope would be about $\frac{500}{10000}=0.05$

Anankena is about 3 km away from the peak and is at about 14 m above the sea level. so the slope is $\frac{490}{3000}=0.16333$

the higher the slope, the harder it is to climb.

so Ahu A Tanga --->3

Ahu Akahanga ------->1

Anakena------>2
