Across Israel there is a wide range of microclimates due to differing soil types and topography. Most areas have limestone based soils with layers of marl and hard dolomites. The color of the soils range from red terra rosa in Judea and Galilee near Mount Tabor to gray in the mountain ranges stretching from Mount Carmel to Zikhron Ya'akov. Marine sediments are found in the loam soils of the coastal plains and at the base of the elevated foothills around Binyamina-Giv'at Ada and Latroun. The Golan Heights and parts of the Upper and Lower Galilee regions have significant layers of basalt deposits of clay and tuff created by centuries of volcanic activity and lava flows. Wind blown sediment deposits help create the loess based and alluvial sand soils of the Negev area.
