### surface:

Impervious surface
* are a source of increased runoff, which contributes to erosion.
* can also cause stream water temperatures to rise, damaging fish habitat.
* change the flow of stormwater over the landscape.
* contribute to the hydrologic changes that degrade waterways.
* increase both the amount of and speed in which stormwater travels.
* represent a major component of the intensive land uses that generate pollutants.
* result in more storm water running directly into the lake.

### surface:

Interface
* are application programs
  - connections
  - essential structures in biological systems
  - overlap
  - surfaces
* are the exposed methods and properties of a particular object
  - most important aspect of most materials
* change because people find better ways of doing things.
* define how information is passed between adjacent layers in a given computer.
* is the largest commercial carpet manufacturer in the world
  - point of contact between the person and the content
  - world's largest manufacturer of commercial carpeting

### surface | interface:

Haptic interface
* apply robotic techniques to develop better ways to interface humans and computers.
* provide force and touch feedback to the human from a computer.

Land surface
* Most land surfaces radiate heat.
* Some land surfaces are produced by erosion.
* are held together by multiple forces.
* have a higher specific heat than water surfaces.
* is solid, so molecules can only vibrate more when they absorb radiation.
* react quickly to heat gain and loss, becoming warm in summer, cold in winter.
* show up as gray and ocean surfaces nearly black.
* sinks relative to sea level.
* tend to appear gray.

Natural surface
* Many natural surfaces act as a diffuse reflector to some extent.
* are rough and erodible to different degrees.

Ocean surface
* Most ocean surfaces absorb energy
  - solar energy
  - expose to air
* tend to reflect the least visible light, so they tend to be the darkest features.

Optical surface
* All optical surfaces are anti-reflection coated.
* are polished and protected with damage-resistant reflective coatings.

### surface:

Pavement
* also has a major impact on water quality.
* belong to pedestrians.
* can occur on spatial scales ranging from a few square meters to many square kilometers.
* includes sections.
* is located in cities
  - driveways
  - freeways
  - ground
  - towns
  - used for hitting
* paved surface
* provides stability.
* rapidly deteriorate as base and subgrade layers become saturated.
* reappears from time to time, especially under bridges.
* reflects brightly across all wavelengths
  - or absorbs heat, depending on whether it is light or dark in color

### surface | pavement:

Asphalt pavement
* is close to medium gray as is some tree bark.
* mixture of rock and sand held together by liquid asphalt cement.
* oxidize over time and becomes increasingly brittle.

Porous pavement
* allows water to percolate through the soils.
* operate in a similar fashion to infiltration trenches.

Photosphere
* are part of sun
* is where photons can escape more easily without further interaction.

Platform
* allow services.
* are computer operating systems
  - documents
  - economies and places where people express themselves
  - flat areas
* are located in arenas
  - buildings
  - concert halls
  - depots
  - docks
  - museums
  - stages
  - structures
* are used for presentation
  - speaks
  - speechs
  - supporting
  - vehicle designations, such as minivan, light truck, and passenger car
* enable customers.
* serve general purposes
* support walls.

### surface | platform:

Backstage
* includes right stages
  - sections
  - stage rights
* visual tool for building database-powered Web sites.
