Atmosphere, Feedback loops, Climate change

Carbon dioxide is the most abundant of these:

• feedback loops

• greenhouse gases

• particulate matter

• fossil fuels

Methane is a greenhouse gas.

• True

• False

Weather and climate mean basically the same thing.

• True

• False

What is the greenhouse effect?

• The warming of a planet due to trapped radiation by greenhouse gases.

• The cooling of Earth due to air pollution.

• The heating of a solid, such as a rock and dirt.

• The cooling of the oceans from ice caps melting.

Based on the graph, which country releases the most greenhouse gases?

• Russia

• Brazil

• China

• U.S.

Polar Ice Caps are melting due to an increase in Earth's temperature. This lowers the albedo of Earth, which in turn increases Earth's temperature. This is an example of what type of feedback?

• Negative

• Neutral

• Positive

• Ecosystem

An increase in Carbon Dioxide levels in the atmosphere could lead to which of the following?

• Increase in temperature on Earth

• Decrease in Albedo on Earth

• Change in overall climate on Earth

• All of the above

Climates are classified according to two major factors:

• elevation and precipitation
• latitude and temperature
• elevation and latitude
• precipitation and temperature

What does ozone in the atmosphere do?

• it absorbs and traps heat energy
• it provides a place for water vapor to condense
• it protects against harmful uv radiation
• it helps plants grow

Which of the following prevents UV rays from reaching Earth?

• The ozone layer
• The biosphere
• The lithosphere
• The hydrosphere
