1. Where to most deserts occur on earth
2. Explain the process of Rainshadow effect and include adiabatic cooling in your answer.
3. Name one example of an organism for type I,II and III in the desert.(basically name an example of an organism that is that type)

1. Mostly along 30 degrees North and South

2. As air encounters a mountain, it is forced upwards, expanding the volume and making it cool. The moisture in the air begins to condense and can come down as precipitation. On the leeward side of the mountain, the air is compressed, increasing the temperature so that the now drier air can hold more moisture. This is the process of adiabatic cooling. The air can also collect moisture from the land on the leeward side of the mountain. This effect causes little precipitation and moisture on the leeward side of the mountain, creating deserts through the rainshadow effect.

3. Type 1: Camels
Type 2: Pinyon Jay
Type 3: Zebratail Lizard

Yep, looks good. Your turn!

Here we go:

1. Name two ways to prevent soil erosion.
2. Describe the sulfur cycle.
3. What's the largest desert of any type in the entire world?

Sorry, they're kind of vague, but have fun!

1. No-till agriculture and alley cropping
2. Major steps: mineralization (organic-->inorganic), oxidation of various inorganic compounds to sulfate, reduction of sulfate to sulfide, and incorporation of sulfide into organic forms. Sulfur is mainly found in oceans and sedimentary rocks.
3. Antarctic

1. Edaphic savannas are created by soil conditions. An example is a savanna in Nigeria (not sure about this??)
2. The ozone layer.
3. The Montreal Protocol?
4. Antartica
