Principles of Climate Impact on Natural Environment

  

All questions should be rely on the slides, Question 1 is gonna be watching the video, question 2 and 3should rely the photo i sent below which is the page 64,65,66 and 107 which is the table 7.4 and 7.5 from 66 for question 2 and page 107 figure 10.1 for question 3. Question 5 will be rely on the figure 20.3 which i sent a photo below



1) Based on the video “World climate and landscape” (2 parts, total 1
hour) on the class website, briefly describe the major characteristics
of climate and vegetation in each zone. (25pts). Note: the information
should include geographical locations, major climate features (such as
temperature, precipitation, etc.), major vegetation types and crops if
available. Please only provide bullet points.

To watch the video, you should be using either Firefox, Safari,
Internet Explorer, or Microsoft Edge as your browser to log-in to the
CCLE course website for streaming access. Google Chrome currently does
not support our streaming.

After logging into the CCLE course website, you will find a tab on the
left-hand side titled, Media Resources. you should click on that
tab, and you will find the Video Reserves option that will list the
media available for streaming. In addition, physical copies of titles
available for streaming can be viewed in the Media Lab located on the
2nd floor of Powell Library, Room 270.

In order to stream media, on or off campus, you must be connected to
the Virtual Private Network (VPN) from BruinOnline. The VPN serves as
a proxy server to authenticate you and grant you access to restricted
material. Dependent on the individuals operating system, the
appropriate VPN Client can be installed following the indications
available here:
https://www.it.ucla.edu/it-support-center/services/virtual-private-network-vpn-clients
or 
https://ucla.service-now.com/support?id=kb_article&sys_id=KB0010936.

2) Describe major geographical locations of glaciers and Sea ice and
their residence time.
Briefly describe how the three components (Rn, H, LE) in (warm)
glaciers energy balance affect glaciers ablation (i.e., melting,
evaporation, sublimation, etc.) and which factors affect influence of
these three components. Note: Please use the information in Tables 7.3
and 7.4 on Page 84-85 in the Reader V2 in your discussion. (20
points).

3) Based on Figure 10.1 (Page 125 in Reader V2), briefly explain the
general relationship between sea level, land, vegetation, CO2,
temperature as well as the roles of super-continental cycle and
mountain building (You do not need to discuss mechanisms in detail).
Note: You may start the discussion with low sea level. After the
general discussion, then choose Cambrian period to confirm these
relationships. (25pts).

4). Describe the photosynthesis process. (it is not necessary to write
the chemical equation). Very briefly describe the definition of GPP
and NPP. How C/P burial ratio affects

photosynthesis and the role of its change in Earths history on
atmospheric CO2 concentration change (15pts)

5). Based on carbon emission, natural vegetation photosynthesis
processes, land use and land cover change, and ocean absorption shown
in the figure below, calculate the CO2 increase in atmosphere (15pts).
Note: You need to provide very brief explanation for each component in
the carbon cycle. You DO NOT need to discuss the carbon transfer
within ocean.
