For the second Milestone you will continue to build upon the work you began in the first Milestone. Make sure you continue to use the climate impact/hazard you identified in the first Milestone. The second Milestone will add detail on the role of Earth’s

Section1:

In the May 2010years in the China Gansu Zhouqu County , Gannan Tibetan Autonomous Prefecture was hit by a wave of serious natural disasters, the catastrophic mudslides. The mudslides buried the areas under as much as 7meters of suffocating sludge. Have a 1.765 people died in that disasters, and the damages totaled a $759 million.

Section 2

Earth cycle include carbon cycle, water cycle and others. Human activities also affect the earth system and affect the earth cycle. “The sister coming is when Water, Phosphorus, Nitrogen, and Carbon. doesn't have sufficient amounts of that nutrient, all the other cycles don't work properly. The most important change is because the Carbon and Water.” (Mudslide in Sicuan province) The definition in the Wikipedia of Landside“is a form of mass wasting that includes a wide range of ground movements, such as rockfalls, deep failure of slopes, and shallow debris flows.” “Slope material that becomes saturated with water may develop into a debris flow or mud flow”. (Wikipedia) I also find the weather and climate in recent year of Gansu China; I find the rainfall are increased. So in other way we also can say the landside of the Gansu have the reason of the increased rainfall. And in the process of I finding the information, my analysis was confirmed, The People's Daily has argued that the mudslide was due to a "perfect storm" of natural events, including "soft" "weathered" rock, heavy rainfall and drought.”

Section 3.

I think whether these influencing factors have been consistent over time. the ecosystem on earth is a cycle. Also the each component interacts each other.

The exchange of material and energy will forming a rich natural resource and

the earth environment suitable of human existence. It also breeds many natural disasters that endanger human beings. the “influencing will not change in the earth cycle.

Section 4.

I think some risk of a repeat even are being reduce by human scientific efforts. We through study, we have basically recognized with the disaster such as landslides, mudslides, desertification, rocky desertification, water pollution.Humans have proposed solutions and prevention measures to prevent disasters. We also do some work for research the earth cycle effect , explore the coordination and balance of the earth system,study the various components of the earth system links between interaction, provide abundant natural resources for human society. People are using their own efforts to reduce risk.
