27. Orographic Rainfall The dry air mass becomes warmer, with little chance of rain. Deserts are often found on the leeward side of large mountain ranges Warm moist air approaches a mountain barrier The air mass is forced to rise as it hits the mountain and condenses into clouds Orographic rainfall occurs on the windward side of the mountains The air mass, now drier, flows down the leeward side of the mountains

Photosynthesis takes place in the green stem (the cactus has no leaves) Thick cell walls that do not break when they dry out A thick, waxy coating keeps the water inside the cactus from evaporating. Instead of leaves, most cacti have spines or scales (which are modified leaves). These spines and scales do not lose water through evaporation (unlike regular leaves, which lose a lot of water). The spines protect the cactus from predators (animals that would like to eat the cactus to obtain food and/or water)
