SC.912.E.7.7 Identify, analyze, and relate the internal (Earth system) and external (astronomical) conditions that contribute to global climate change.

Day 1 What do the following terms mean? –Climate Change –Ozone –Infrared energy –Greenhouse Effect

Vocabulary –Climate Change Long term weather patterns –Ozone A gas found in the earths atmosphere (O 3 ) –Infrared energy Type of energy from the electromagnetic spectrum –Greenhouse Effect The trapping of infrared energy in the earths atmosphere

DAY 2

According to the graph below, what wavelength of energy does the Earth receive in the greatest intensity?

Name the primary gas which absorbs ultraviolet (UV) from the sun.

Name the three primary gases which absorb infrared (IR) energy

Why is the ozone layer important? It protects the Earth from UV which damages crops and causes cancer in humans.

Why is it warmer on a cloudy night than on a clear night? Clouds (H 2 O vapor) absorb IR energy radiated by the Earth. On a clear night, the IR energy escapes back into space.

DAY 3 Reading passage

Describe four natural processes that can cause climate change?

Earth’s climate is constantly changing. Climate Change Antarctic Temperatures for Past 420,000 Years Thousands of years ago Temperature difference (°C) compared to present

Earth’s climate is constantly changing. Climate Change Global climate changes can be caused by changes in Earth’s energy budget and by the interactions among Earth’s spheres. Causes for climate change include variations in Earth’s motions, the location of the continents, variations in sunspots, and gases and ash ejected into the atmosphere by volcanoes.

Natural Processes That Change Climates Climate Changes  Volcanic Eruptions The presence of volcanic aerosols (ash, dust, and sulfur-based aerosols) in the air increases the amount of solar radiation that is reflected back into space. This causes Earth’s lower atmosphere to cool.  Ocean Circulation Changes in ocean circulation also can result in short-term climate fluctuations.

Natural Processes That Change Climates Climate Changes  Solar Activity When the sun is most active, it contains dark blemishes called sunspots. The formation of sunspots appears to correspond with warm periods in Europe and North America.  Earth Motions Geographic changes in Earth’s land and water bodies cause changes in climate. Changes in the shape of Earth’s orbit and the tilt of Earth on its axis are other Earth motions that affect global climates.

DAY 4 GREENHOUSE

Explain the greenhouse effect. Include a diagram which shows the change in wavelength.

Just like a greenhouse, the gases in the atmosphere ---especially CO absorb re-radiated infrared energy.
