State Plane Coordinate Systems

The state plane coordinate system (SPCS or SPS) is a collection of 124 coordinate systems or geographic zones prepared for particular regions of the U.S. Every state consists of one or more than one state plane zone, the boundaries of which generally follow the county lines. Inside the U.S., there are 110 zones in total, 10 more zones in Alaska, 5 in Hawaii, and 1 for Puerto Rico and US Virgin islands. The system is extensively used for geospatial and geographic data assembling by the state and local governments.

Question

Tension cracks only develop if the soil is fully saturated near the ground
surface.
The presence of water in the crack alone tends to increase the shear
stress developed along the slip surface shown in the figure above,
while reducing the effective stress component normal to the slip
surface.
When calculating the FoS against the slip surface shown above, the
soil shear resistance along the crack should be omitted whether the
crack is filled with water or not.

For the slope shown in the figure below, which of the following
statements apply (select all that are correct):
i
Crack filled
with water
Slip surface
Cracks observed at the surface behind the crest are generally due to
tension stresses that develop in cohesionless soils (coarse-grained
soils).
