22 Uses of Sand

Sand helps to improve resistance (and thus traffic safety) in icy or snowy conditions. We need sand in the beaches where tides, storms or any form of preconceived changes to the shoreline crumble the first sand. Sand containing silica is used for making glass in the automobile and food industry even products for the kitchen. Sand is a strong strand which is used for .

Cone snail

Cone snail

Cone snails use a radula tooth as a harpoonlike structure for predation. Each of these harpoons is a modified tooth, primarily made of chitin and formed inside the mouth of the snail, in a structure known as the toxoglossan radula. (The radula in most gastropods has rows of many small teeth, and is used for grasping at food and scraping it into the mouth.)

Trees 200 to 300 years old produce the greatest number of cones. For example, a stand of oldgrowth Douglasfir may produce 20 to 30 times the number of cones per hectare that a secondgrowth stand 50 to 100 years old produces. Seed Production and DisseminationMajor deterrents to natural regeneration of Douglasfir include limited seed supply; consumption of seed by insects, animals, and ...
