<h2><em>reason for climate change and global warming</em></h2>
- <em>the climate and the earth's temperature by burning <u>fossil fuels</u>, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.</em>

The area just north of Lake Baikal is called the Irkutsk Oblast, where the city of Irkutsk is located (in Siberia).
Um, I disagree. Maybe you should take some time to understand how Earth works!
Answer:
Frost Action in temperate regions of the world
Salt weathering in coastal and arid regions
Thermal expansion and contraction in tropical climates
Explanation:
Mechanical weathering is also known as physical weathering, and it entails the disintegration of rocks into smaller fragments.
Weathering processes generally take place slowly with time. Also, they are geography specific. One such means is frost action. In frost action, a freezing and thawing cycle catalyze rock disintegration. When water freezes, it expands 9 percent in volume. The expansion causes stress which forces rock disintegration.
Also, in some coastal and arid regions, salt crystals may grow from saline solutions on evaporation. When these salts crystallize in interstices of rocks, they produce stress and widen pores. This weathering process is very slow.
Another very effective mechanical weathering process which occurs in tropical regions of the world is thermal expansion and contraction. It's a prolonged process in which daily heating and cooling of rocks cause a rock to expand during the day and contract at night. This alternating process causes cracks to open up in a rock body.
