The tropical forests can roughly be divided into two major groups, tropical evergreen forests and tropical deciduous forests. The division is made in accordance to the characteristics of the trees.
The trees in the tropical evergreen forests are green throughout all of the year. The reason behind this is that they have constant temperature all year long, and constantly high amounts of rainfall all year long, so there is no need for them to shed their leaves.
The trees in the tropical deciduous forests, on the other hand, are shedding their leaves. This means that in one part of the year these trees have green leaves, while in the other part of the year they are shedding their leaves and the branches are stripped. The main reason behind this is that the rainfall occurs only seasonally, when pretty much all rainfall for the year falls in few months. After that, a very long period of drought and very high temperatures starts. In order to survive and not get damaged, the trees are shedding their leaves, thus they almost put them selves in an hibernating phase until the next rainy season.
Answer:
The amount of sunlight changes when moving between north and south.
Explanation:
Climate change results from global warming which is an increase in the temperature of the earth.
The sun is the primary source of temperature change on earth, and latitude place a great role in the amount of sunshine that come to an area. Places at high latitude receive less sunlight when compared to places at low latitude, this in turn determines how warm or cold a region can be. On the other when moving from east to west, it is along longitudinal lines and this can be on same elevation, thus there are no significant changes in temperature.
Therefore sunlight plays a key role in altering the temperature along latitudes.
