The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbon dioxide, nitrous oxide, and methane, for example) trap energy from the sun. Normal warming is mostly caused by natural gases.
Earthquakes are caused when plates shift. Hope that helps!
Into tropical savannas or steppes, in Africa, tropical wet climates transition into seasonally wet or dry tropical woodlands, followed by another transition.
The tropical savannas are identified by tall grasses and occasional trees. It can result from either climate, soil conditions, animal behavior, or agricultural practices, which limit the occurence of trees.
