Risk, Hazards, and Population
1.

What role does social vulnerability play in the perception of risk?
Social vulnerability influences an individual process of assigning risk to an object, condition
or action.

2.

Name two places or regions in the world that are highly populated.
China
India

Climate Change
3.

Define climate change. How is it different than weather?
Climate describes how the weather is like over a long period of time while weather refers to
short-time changes.

4.

Name two natural processes that contribute to a changing climate on Earth.
Variation of the sun’s energy reaching earth.

Changes in the reflectivity of the earth’s atmosphere an surface.

5.

Describe the Greenhouse effect. Which non-condensing greenhouse gas contributes a
relatively high percentage of greenhouse warming?
Greenhouse effect occurs when the sunlight is absorbed releasing infrared radiation which
are absorbed by the greenhouse gases like water vapor, carbon dioxide and methane which

QUESTION-ANSWER

3

act as a cover making earth warmer. The non-condensing greenhouse gas contributes high
percentage of greenhouse warming is carbon dioxide.

6.

Look at the Vostok ice core graph. Describe the general trends (increasing or decreasing) for
solar radiation, global average temperature and carbon dioxide (CO2) levels levels over the
past 400,000 years.
According to the Vostok ice core graph, over the past 400,000 years there has been a distinct
relationship between higher temperatures and increased carbon dioxide. The graph shows
that the rise and fall of global average temperatures and CO2 emissions is a natural cycle
that has been happening in the past 400,000 years. Although, the net change of solar
radiation for the past 400,000 years is fairly small as compared to temperature and CO2.

7. Describe what has happened to the Antarctica, Arctic, and Greenland ice sheet and sea level rise
in response to these trends.
Because of the rising temperatures due to climate change Artic sea coverage is shrinking by
3 percent per decade while the Antarctica sea ice is growing in about 1...
