We developed Natural Earth as a convenient resource for making custom maps. Unlike other map data intended for scientific analysis or military mapping, Natural Earth is designed to meet the needs of production cartographers using a variety of software applications. Maximum flexibility is a goal. Natural Earth Vector comes in ESRI shapefile format, the de facto standard for vector geodata.
A gizzard is a sack like organ at the back of the earthworms throat. The gizzard basically chews the earthworm's food since the worm doesn't have any teeth. The crop is a thin â¦ ner organ closer to the head. The crop stores food.
What is a gizzard of chicken? The gizzard is the lump of muscle that grinds the food of the chicken. The food passes into the crop, and is softened, then through the stomach where digestive juices are adâ¦ded, then into the gizzard,where the food is ground up by all the bits of grit the bird eats from day to day.
