Which statement BEST describes the relationship between human activities and the availability of soil? A. Removing vegetation during logging or construction can reduce the availability of soil due to erosion.
B. Conventional farming increases the availability of soil because farmers make new soil every year.
C. Human activities can move soil from one area to another but cannot create or destroy soil.
D. Human activities cannot affect the availability of soil because soil is made by natural processes

show the diagram then i will answer

1 the 4 is sig

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
