ES Chapter 3 Sections 1 and 2

What layer of the atmosphere is closest to the Earth's surface, is where the weather occurs & most living things exist.

Only natural processes influence the quantities of carbon dioxide and methane in the atmosphere.

The following greenhouse gas is also a product of respiration:

This layer is above the troposphere and contains the protective ozone layer:

The following is NOT a greenhouse gas:

One source of the greenhouse gas carbon dioxide is the combustion (burning) of fossil fuels.

Transform boundaries are where plates slide past each other. An example is:

The greenhouse effect is necessary for life to exist on Earth.

An example of a divergent boundary where plates move away from each other & magma &new rock emerge between is:

This greenhouse gas can be released from thawing permafrost, natural gas leaks, and ungulates' flatulence.

An example of convergent boundaries where plates collide, the crust becomes thicker & eventually mountain ranges form:

This layer of the Earth is the most dense:

This process is when materials are transported from one place to another by a natural agent, such as wind or water.
