soil formation, geological cycle , weathering of soil, physical and chemical weathering, type of soil, transported soil etc is include in this material
This comprehensive presentation is a broad unit on soil, soil formation and soil layers. The unit gives performance expectations, key vocabulary, types of weathering, soil components and types, soil composition, formation, horizons, hazards, properties, characteristics. Finally the unit covers soil nutrients and forest systems.
Can best be used at High and Junior high schools, by hobby gardeners, farmers and as a college introductory presentation or as a basic refresher. Also elementary teachers can use this to "get up to speed" on the fascinating topic of soil!
Soil Lab v4 is the final version for 2015.
Deserts are landforms of sand and sediments. They are the cradles of centrifugal eolian forces. Among all the terrestrial ecosystems, deserts are typical landforms due to their unique ecological conditions.
Desert and near-desert areas cover nearly one-third of the land surface of the globe . Deserts alone covers about one-seventh of the land surface.

Subsoil and pines mortality in yatir forestNir Herr
In Yatir forest, located at the southern edge of the dry Mediterranean region in Israel, a patchiness mortality pattern of pines was observed after continuous droughts. The objective of the study was to identify the environmental factors that caused the mortality. Our results suggest that the preferable environment for planting pines in this region is chalk overlain by shallow and stony soil. Storage of water in this rock-soil system is the key factor affecting the survival and success of the forests

41. Food Web Mayflies In spring, water temperature needs to be in the low 40s. Peak hatches occur when the water temps hit 46 degrees and up. In summer, especially evenings, water temp needs to be in the 60 degree minimum. For fall mayflies, peak hatches will happen when the water temp is over 46 degrees. Egg development is highly dependent upon a narrow temperature range for survival, with maximum hatching rates at 15.8 °C and 1.9 - 5.2 °C for Other predators include birds, spiders, dragonflies, damselflies, trout, and insectivorous biting midges (McCafferty 1998). Below the surface, more activity takes place. 90% of the food trout eat is taken below the surface. That generally means nymphs.
