1. Af would be a tropical wet climate, characterized by a fairly constant warm temperatures throughout the seasons, they are generally wetter than other climates and there is a greater temperature from day to night, however these again remain constant throughout the year. Rainfall is frequent and heavy mainly during the afternoons turning to clear skies by the evening hours.
Am climates are is very similar to an Af but with a short summer followed by heavy rains. These climates are located along the Southeast Asia, India, and in northeastern South America (Ahrens, 2015).
Aw again is very similar in rainfall to the other two however, it has a long dry season that last for three months or more. The amount of rainfall in the wet months is substantial.
All three of these types of climates are responsible for our rainforest growth as well as the savanna grasses.
2. A positive feedback mechanism is an increase in temperature that is reinforced by the other processes. An example of positive feedback mechanism would be the water vapor-greenhouse feedback where strengthening of the greenhouse effect raises the air temperature and more water vapor to evaporate into the atmosphere (Ahrens, 2015).
A negative feedback mechanism on the contrast tend to weaken the interactions among the variables rather than reinforce them (Ahrens, 2015). A good example would be chemical weathering-CO2 feedback where carbon dioxide is being removed from the atmosphere while a chemical reaction is happening on the surface releasing carbon dioxide causing a cooling of the air and combating against the global warming.
3. Milankovitch Theory is three separate cyclic movements combine to produce variations in the amount of solar energy that falls on the earth (Ahrens, 2015). These three cycles are eccentricity or change in the shape of the earths orbit, next we have precession or wobble of the earth's axis, and finally obliquity or tilt in the earths orbit
