Explain how scientists can have multiple theories about the effects of global warming.

The global climate is very complex. There are several different factors to consider such as temperature, precipitation, humidity, and overall climate. All of these theories are based on predictions. It is hard to predict what will happen in one region and how that will affect other regions on a global scale. Nobody knows with 100% certainty what will happen.

Explanation:

this is a good question! i'll do some research and come back when i have the answer!

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
