<u>Answer:</u>
Subsistence agriculture is when the activity of growing food is not associated with economic gains and is only carried out in order to feed the cultivator himself and his family.
<u>Explanation:</u>
The word subsistence literally means support. The farming that is done by the farmers to support their survival is thus known as subsistence farming. In subsistence farming, the farmers choose to grow food that would only be enough to fulfill their own needs of survival.
There are no economic gains possible from subsistence agriculture as there is no surplus produce that can be traded to fetch economic gains.
Because the time span of Earth's past is so great, geologists use the geologic time scale to show Earth's history.

Answer:
1.422
N/m²
Explanation:
pressure (P) = ρ g h
where ρ= density of continental crust
g= acceleration due to gravity
h is the depth given
density of continental crust is equal to 2.9 g/cm³
= 
g=9.81 m/s²
height = 50,000 m
now,
pressure (P) = ρ g h
pressure (P) =
=1.422 N/m²
