reason rocks are interesting.
pursuit of a career in geology.
importance of learning geology.
impact of a good science education.

I think it's C. The importance of learning geology. for example; if I were to talk about the importance of architecture it would only be important to me and  it's design is interesting to me. Architecture would be the main topic of my personal summary, not how interesting the little things are about the topic. Hope this helps :)

this is the answer , p = 1 + (1/10)x

step-by-step explanation:

we have,

at sea level pressure is 1 atmosphere (i.e at x =0, p0=1 atmosphere)

at depth 23 meters , pressure = 3.3 atmosphere

since the pressure increases at constant rate as the depth increases, so we can write a relation as:

p =p0 +   kx   , where p is the pressure  , p0 is the initial pressure, x is the depth and k is constant rate of increasing.

to find constant rate k, plug p = 3.3 , p0 = 1 and x= 23 meters

we get,

  3.3 = 1 + k * 23

k = 2.3 / 23   = 1/10

so we can write the function formula as:   p = 1 + (1/10)x
