Some people want to explore movement through rivers, oceans, and to the tops of mountains and skyscrapers, but it's important to remember that such places may have restrictions, and safety should always come first.

The flight takes a period of one to three days— then they are gone after shedding their wings. What is this all about? Nothing other than termites—why they emerge after a few rains, their economic importance (pros and cons), and what to do when they emerge.

Soil: Characteristics and Benefits to Humans Colors of soil can be red, pale brown, dark brown, black, white, or gray. Soils from different countries and regions vary in color; iron oxides result in red soils which are common in tropical regions while salt and calcium carbonate in soils result in white soils. Soil as a Natural Resource Soil is a natural resource found all over the world. Even small islands have dry land covered with sand. Beneath water bodies, different kinds of soil exist. Mountainous areas are also surrounded by sand. Rocks break down into smaller particles due to land degradation, mining, weathering, and natural events such as rainfall and volcanic eruptions. This process enables plants to grow even in mountainous areas and on concrete surfaces. Benefits of Soil to Humans...
