Angular grain
* are usually the result of mechanical weathering like frost wedging.
* show often cataclasis and fissures.

Buckwheat
* are especially diverse and abundant in the desert regions.
* attracts hoverflies.
* builds organic matter and adds phosphorus to the soil.
* comes from South Dakota.
* consists of the seeds of a plant native to Central Asia.
* grows best in a cool, moist climate, such as is found in parts of the Northeast
  - when conditions are moist and cool
  - in most soils, including infertile and acidic ones
  - well on field pea or dry bean stubble or summer fallow
* is grain
  - herbs
  - part of buckwheat
  - plants
* produces a dark, strong-flavoured honey, which is usually sold for a premium.
* releases chemicals that prevent weeds from germinating.
* responds to good summer rainfall, but is intolerant of waterlogging.
* supplies several kinds of food.

Coarse grain
* can often substitute for each other in feed use.
* refer to all other cereals except wheat and rice.

Colored grain
* Many colored grains are biotite and muscovite.
* are muscovite and biotite.

Coral grain
* are grains of the skeletal structure of reef-building coral that has become defunct.
* dominate sands where coral health is poor.

Couscous grain
* is ideal for children, because couscous is made with a cereal, wheat.
* tend to bind together in the cooking process, so fluff the grains with a fork.

### substance | particle | grain:

Granule
* accumulate in an area devoid of vegetation.
* are a pleasant-tasting, concentrated way to supplement
  - coarse formulations of dusts made for broadcast treatments
  - dry, granulated materials that come ready to use
  - indistinct
  - pesticides formulated on large particles of various materials
* are present in the tissue
  - within the cytoplasm
  - regions of the sun where hot solar material comes to the solar surface
  - rich in plant nutrients
  - suitable in lawns and other areas subject to moisture or frequent watering
* are the most abundant membrane bound organelle
  - effective with the use of a liquid insecticide
  - tiny balls or pellets on which the medication is impregnated
  - usually more expensive than powder
* can fall through to the soil surface, without being intercepted by dead vegetation.
* come off shingles.
* contain an array of antimicrobial protein
  - histamine
* disappear when decalcification processes are applied.
* dissolves rapidly and completely in spa water.
* lost by erosion and freeze-thaw cycles increase the area of exposed bituminous surfaces.
* often appearing on the surface are soredia.
* work best on a smooth flat surface with low stubble residue.

### substance | particle | grain | granule:

Chondrule
* are abundant throughout
  - characteristic of the major class of stone meteorites known as chondrites
  - granules
  - highly diverse in composition
  - light gray-tan in color
  - millimeter-sized rounded igneous rocks within chondritic meteorites
  - part of chondrites
  - particles formed by no earthly process
  - spherical glassy objects and are the main components of ordinary chondrites
* contain moderate to small abundances of olivine.
* have unusual textures compared to most other chondrites.
* lack circular gas bubbles.

Larger grain
* are more likely to absorb light photons than a smaller grain.
* can only roll along the ground.

Long grain
* describes fibers running parallel to the longest side of a sheet.
* is three times as long as it is wide, for instance.

Millet
* Much millet is grown in China, India, Manchuria, the USSR, and Africa.
* are a major food staple in much of Asia, Eastern Europe, and the western part of Africa
  - seeds
* grow well in arid and semi-arid environments, requiring less water than any other grain.
* is grain
