### direct health risk:

Contaminated water
* can also be a factor in transmitting the bacteria
  - be dangerous to humans and animals under certain circumstances
  - cause many illnesses
  - contain microorganisms that cause disease
  - enter shallow porous aquifers if nearby areas become flooded
  - harm plants, animals, and humans
* causes millions of preventable deaths every year, especially among children.
* direct health risk.
* imposes harsh economic and social costs on people.
* is bad for our health as well as the livelihood of aquatic species
  - difficult and expensive to manage once it becomes dispersed underground
  - heated to form steam
  - just like a food poisoning in a healthy person
  - one source of infection
* is the most common source for outbreaks other than in institutions
* jeopardizes both the physical and social health of all people.
* poses an increased risk for infection in immunocompromised patients.

Direct object
* can be nouns, pronouns, phrases, or clauses.
* is an object

Direction
* Change the orientation of the frames within a frame.
* are true only along the equator.
* is determined by the position of the sun
  - in degrees from north as measured by a compass
  - inclination
  - messages
  - paths
  - positions
* is the angle between a line and an arbitrary chosen reference line
  - application of a leader's philosophy, the actions resulting from it
  - used to represent positive or negative effects
* plays an important role in a soldier's everyday life.

### direction:

Magnetic north
* is determined by the earth's magnetic poles
  - direction
* lies north of Canada in the islands of the Arctic Ocean.
* varies with each longitude and is different each year.

Stage direction
* is direction
  - instruction
* is part of drama

### direction:

Wind direction
* All wind directions are magnetic.
* are magnetic and are the direction from which the wind is coming
  - true directions
* big factor in the weather.
* can also change dramatically when entering a fjord or coming around points
  - foretell temperature, humidity, storm or clear
* can make a big difference as in flying with the wind at their backs vs. a headwind
  - or break sizeable surf
* is also critical for determining gas or vog concentrations at a given location
  - an indicator of the direction that the wind is coming from
  - as important as wind velocity in reducing the damage caused by drift
  - defined by the direction it is coming from
  - determined from the variations in rotor speed
  - given as the direction the wind is coming from along a compass direction
  - measured as the direction from where a wind comes from
* is measured by a wind vane and wind speed is measured by an anemometer
  - coupled to a precision low-torque potentiometer
  - which is an arrow mounted on top of an elevated site
  - recording the direction the wind is coming from
  - from which it's blowing
  - in degrees from true north
  - using an aluminum vane directly coupled to a precision potentiometer
* is measured with a rotating vane
  - an instrument called a weather vane
  - wind vanes or wind socks
  - our independent variable, so it goes on the horizontal axis
* is reported as the direction from which the wind is blowing
  - by the direction it is blowing from, according to the compass
  - represented by an arrow pointing in the direction from where the wind is coming
  - the compass point from which the wind is coming eg south, south west, west etc
* is the direction from which the wind is blowing
  - the wind blows from
  - magnetic bearing of the true wind
  - true wind direction accounting for the rotation of the tower during the year
  - where the wind has travelled from
* refers to the direction in which the wind is blowing.
* reverses itself in a hurricane.
