Describe a Heat Budget.

The balance between the total energy received and the total energy emitted over a period of time.

Define Radiative Balance:

Constant average temperature; when energy absorbed equals energy emitted.

Explain the onset of an Ice Age.

An energy deficit in the Earth's heat budget, where energy emitted to outer space is greater than energy absorbed from the Sun, resulting in global cooling.

El Nino refers to a change in the ocean currents where a large body of warm water replaces cold water off of the Pacific coast of South America. This event impacts atmospheric conditions world wide.

Describe Global Warming.

A term used to describe the current warming period here on Earth. Questions exist as to how directly or indirectly man is responsible for these trends by burning fossil fuels and increasing CO2 concentrations in the air.

How might Sun spots effect the Earth's heat budget?

These dark spots on the Sun's surface indicate an increase in radiation being emitted by our star. Thus, warmer temperatures on Earth.

Explain why major volcanic eruptions may cause Earth's surface to cool.

The concentration of aerosols in the atmosphere will reflect insolation back into outer space. Less EM radiation to the surface means cooler temperatures.

Define desertification:

The growth of deserts due to human actions and choices. This consequence is purported to raise global average temperatures.

Discuss deforestation.

Human activities entailing the cutting down or burning of forests, generally to create more farm land. Elevated air temperatures result. (see page 115)

Hypothesize why urbanization may contribute to local climate change.

Cut down the trees, and build roads and buildings that absorb insolation, may lead to micro or small scale "hot spots". Man is responsible for this change.

The annual trend of air temperatures and moisture patterns for a given location. Here in North Rockland, we enjoy fall, winter, spring, and summer.

List three astronomical causes/reasons for seasons.

1) Earth's revolution about the Sun.2) Tilt of axis 23.5 degrees. 3) parallelism.

Can you address all multiple choice questions through page 119? Questions (32-48)?

Please complete and remit to the instructor.

How would the seasons of North Rockland be modified if the tilt of our axis shifted from 23.5 degrees to only 10 degrees?

Cooler summers but warmer winters as the tropics would be defined as only 10 degrees North, to 10 degrees South latitudes.
