What is the mechanism that causes "land subsidence"

• An increase in weight at the land surface

• A reduction in subsurface fluid pressures with sedimentary layers

• The dissolution of soluble bedrock such as limestone exposed at the land surface

• A heavy rainfall for a prolonged period of time

The natural movement of downward of soil, regolith, or rocks under influence of gravity without seismic motion or heavy rainfall is collectively called

• Avalanche

• Mass wasting

• Crucial abrasion

• Erosion of wind

This map shows particular information needed for analysis purposes. They are usually derived from original thematic maps and are translations of base data into customized categories such as severe flooding, erosion, steep slopes, etc

If land is limited, which of the following is the best way to plan for parking lots

• 30 degree parking on both side of a one way loop system

• two way circulation with 90 degree parking on both side of the drive

• combining service circulation with parking at 45 degree angle

• 90 degree parking on one side of a one way circulation drive

A drainage basin is the total land area that contributes runoff to a given stream. what characteristics of a drainage basin causes it to have an efficient response to rainfall

• permeable soil

• plasticity of clay bottom

• filtration by its wetland

• sloping topography in bowl like formation

A street or road services pedestrian/vehicular traffic from minor roads leading to major roads

• Alley

• Collector road

• Service road

• Motor court
