From the information given:
This activity involves exploring the Zion National Park geology. To achieve this, we need to download the Zion file & open it in Gougle Earth. This is followed by setting the vertical exaggeration to 0.5 & the measurement to feet/miles. The perspective view is also changed to a map view. Now, as viewed in Gougle Earth, the upper portion which is white in nature appears to be steeper than the lower portions. To the Toquerville, the area towards it is remarkably flat with slight undulations.
I believe it was the World Health Organization.
Crude oil is made of several components- called hydrocarbons- mixed together and can be chemically separated. These components are, majorly, fuels. Examples of these fuels are; diesel, petrol, kerosene, liquefied petroleum gas and heavy oils such as bitumen (used on tarmac roads).
An oil refinery is basically a big plant that utilizes the chemistry of fractional distillation to separate the oil components. This involves boiling the crude oil at different temperatures to evaporate the different components that have different boiling points. Each component is later condensed and recovered separately.
Crude oil is a natural resource that is formed over millions of years from organic matter especially planktons. When the organic matter dies and settles at the bottom of oceans, they are overlaid by layers and layers of sediment. This, over time, subjects the organic matter to high pressure and temperatures and they metamorphose into crude oil.

The wetlands at the mouth of the Mississippi river is disappearing majorly because of the human activities that have greatly altered and destroyed the habitat. Human activities such as dredging the wetland for canal, draining and filling for agriculture, grazing and development purposes, etc are the major reasons why the wetlands are disappearing.
The government is already pumping money into saving these wetlands.
