Surface
* All surfaces are energetically unfavourable in that they have a positive free energy of formation.
* Any surface touched by raw animal foods can transfer deadly bacteria, parasites and viruses.
* Every surface can experience a force from the constant impact of trillions of atoms

  - draw water
  - form volcanoes
* Some surfaces have complex shapes
  - conductivity
  - exoskeletons
  - fluid
  - friction
  - impact craters
  - membranes
  - minimal friction

  - move water
* Some surfaces pass through cell membranes
* Some surfaces prevent heat
  - produce light
  - protect embryos
  - push water away
  - reflect rays
  - resist forces
  - simulate the texture of grass, and others are little more than carpet
  - slide across surfaces
  - transmit light
  - use for food storage.
  * A 'surface' is the outer part of something. Most surfaces have a width and a length, but no depth. The two dimensions are width and length
* Waves Several types, travel along the earth's surface or on layer boundaries in the earth.
* acting involves controlling the outward expression of emotions.
* affect appearances
* anchoring can influence the orientation field deep into the bulk of the liquid.
* are also manifolds
  - artifacts
  - aspects
  - coloured and elevated by temperatures
  - critical in the performance and interaction of materials
  - dangerous for motorcycles in some areas
  - flat planes
  - important Most microbes in the environment
* are located in geometry
  - lakes
  - mirrors
  - objects
  - solids
* are made of materials
  - plastic
  - mirror images of each other
  - part of lithospheres
  - plane or convex
  - smooth, plane, or convex
  - some of the simplest, yet most interesting topological objects
  - studied in geometry
* are used for counters
  - paintings
* based inversions occur during long nights when calm conditions and dry air exists.
* become increasingly important in devices, as the dimensions are shrinking.
* can change quickly when the wind shifts, the rain starts or the season turns cold
  - gather energy after they have shot
* clays Typically from river bottoms.
* collect dirt
* come into contact.
* composed of convex planar polygons can be of arbitrary complexity.
* contain grooves
  - transverse grooves
* contaminates such as sulfur can contribute to hot cracking.
* craze, bend and tear and stick together.
* crusting occurs on irrigated, dryland, and rangeland soils.
* display structures
* experience friction.
* features contain clues to understanding the Earth
  - like water, green vegetation, pavement and others have unique spectral reflectance
  - mediating cellular encapsulation in noctuid moths
* have a chemistry of their own
  - tendency to be textured at some level, no matter what the medium
  - characteristics
  - elevation
  - finish

* hoar forms on the surface of the snow at night when it gets colder than the dew point.
* includes sections.
* is an artifact
  - sand coated to provide a weather-resistant textured surface
* lows forming south of the polar jet and bottom-up types of lows are slow to deepen.
* lures can take fish all day long, sometimes.
* melting on polar ice sheets occurs as temperatures increase.
* offer protection.
* piercing propellers require a large amount of air to operate effectively.
* plane of const.
