8. Elevation: There are two types of rainforests; lowland- found in areas of low elevation. They contain tall trees with high canopies, and they receive intermittent precipitation. Cloud- found in mountainous regions and growth is usually thicker than in lowland forests. They gain moisture through mist, rain, and clouds.
9. Average yearly wind speed: The lower levels don’t receive much wind, but the higher the level the more wind there is.
10. Topography: The tropical rainforests range from lowland forests with less rainfall and different plant and animal life to cloud forests that are very lush and thick and contain a very different plant and animal population than the lower layers.
11. Soil Conditions: Soil in the tropical rainforest is low in nutrients. Plants are so lush because they have the ability to store the nutrients from plant decay around them. The soil is so is so infertile because its 100 million years old and has taken a beating from the elements of nature.
