### distribution:

Random distribution
* are typical for many kinds of organisms with widely dispersed individuals.
* show random variances.

Revenue sharing
* are distribution.
* is distribution
* reduces the pressure to give away public funds.

Scatter
* baits early in the morning before grasshoppers start to feed.
* is distribution
  - spread

Unequal distribution
* problem with flood irrigation systems.
* result of unequal, private ownership of the main means of creating wealth.

Water distribution
* highly controversial subject, particularly in arid and semiarid zones.
* is also very unequal, both within countries and among different states.
* major component of geological science.

### disturbances:

Outburst
* floods in the high mountains mean devastating floods for the lowland countries downstream.
* is disturbances
  - expression
  - happening

Ditch
* Some ditches contain water
  - have slopes
* are excavation.
* are the best way to carry water away from roads and to the water table
  - trenches along the river, dangerous for their undertow and slippery banks
  - waterways
* can play an important trapping and processing role.
* especially can be dangerous if ice forms on the top and water is still flowing underneath.
* includes sections.
* is excavation

### ditch:

Trench
* Some trenches are where the water pipes go
  - qualify as confined spaces
* are active with earthquakes and resulting tsunamis
  - ditchs
  - like very deep ditches in the ocean floor
* are the deepest parts of the ocean floor and are created by subduction
  - world ocean
  - longest continuous structural features of the deep-ocean basins
* form the deepest parts of the Atlantic
  - where plates subduct
* includes sections.
* occur along the boundary between two plates that are moving towards each other.
* often are associates with volcanic arcs.
+ Oceanic trench: Landforms :: Oceanography
  * Trenches are active with earthquakes and resulting tsunamis. Most volcanism associated with trench occurs on the continent and not on the seafloor. The western Pacific has island arcsm as do the Aleutian Islands.

### ditch | trench:

Furrow
* are depressions
  - trenchs
  - troughs that allow for plants to be watered without wetting leaves
* lie straight and true towards the horizon.
* retreat like sandcastles Washed by a truculent sea.
* watering every other bed prevents excessive soil moisture conditions in clay loam soils.

### ditch | trench:

Moat
* are deep , wide ditches filled with water
  - expensive to build and, therefore, best suited to peninsulas with narrow isthmuses
  - furrows
* keep animals safely in their space, but allow for an unrestricted view.
  * are deep, wide ditches filled with water. They were usually built near sources of water that flowed into the moats, filling them with water. The moats were filled with water for a few reasons. It made enemies swimming across the moat easy targets. It also made it impossible for enemies to dig underneath the castle walls, which was a common method of attack. It also prevented fires from destroying the castle.

### diurnal animals:

Giant otter
* are diurnal animals
  - mammals
  - more social than river otters, but separate groups tend to avoid each other
  - strictly diurnal
  - terrestrial animals
* are very sensitive to human disturbance
  - social animals
* eat mainly fishes and crabs.
* exhibit a high degree of pair bonding and group cohesiveness.
* have large, fleshy feet with thick webbing that extends to the tips of the digits.
* live in lakes and slow-moving rivers in forested areas.

American pika
* adapt to environments.
* are diurnal creatures, active only in the daytime
  - native to America and can be found in the mountainous regions of North America
* have body temperature.
* have high body temperature
* live in areas.
* seek shelter.
* store food.
