Understanding Atmospheric Systems

What is the natural greenhouse effect?

• The natural greenhouse effect refers to the depletion of ozone in the atmosphere.

• The natural greenhouse effect is caused solely by human activities.

• The natural greenhouse effect is the cooling of the Earth's surface.

• The natural greenhouse effect is the process by which greenhouse gases trap heat in the atmosphere, maintaining Earth's temperature.

How does the natural greenhouse effect contribute to Earth's temperature?

• It causes the planet to lose heat rapidly.

• It has no impact on Earth's temperature.

• It cools the planet by reflecting sunlight back into space.

• The natural greenhouse effect contributes to Earth's temperature by trapping heat in the atmosphere, keeping the planet warm enough to sustain life.

What are the main greenhouse gases involved in the natural greenhouse effect?

• Carbon dioxide

• Methane

• Water vapour

• All of the above

Explain the concept of energy balance in the Earth's atmosphere.

• Energy balance is the equilibrium between solar energy absorbed by the Earth and energy radiated back into space.

• Energy balance refers to the total amount of energy produced by the Earth's core.

• Energy balance is the measure of wind speed in the atmosphere.

• Energy balance is the process of converting solar energy into chemical energy.

What is incoming shortwave radiation?

• The reflection of sunlight off the ocean surface.

• The energy produced by volcanic activity.

• The heat generated by the sun.

• The solar energy that reaches the Earth's atmosphere and surface.

What are the primary sources of incoming shortwave radiation?

• The clouds reflection generate incoming shortwave radiation.

• The sun is the primary source of incoming shortwave radiation.

• The Earth's surface are the main source of incoming shortwave radiation.

• The moon is the primary source of incoming shortwave radiation.

How does the angle of sunlight affect incoming shortwave radiation?

• The angle of sunlight has no effect on shortwave radiation.

• The angle of sunlight only affects longwave radiation.

• Higher angles of sunlight decrease the intensity of incoming radiation.

• The angle of sunlight affects the intensity of incoming shortwave radiation, with steeper angles resulting in higher intensity.

What is outgoing longwave radiation?

• Outgoing longwave radiation is the ultraviolet radiation reflected by the Earth.

• Outgoing longwave radiation refers to the heat absorbed by the Earth from the sun.

• Outgoing longwave radiation is the visible light emitted by the Earth.

• Outgoing longwave radiation is the infrared radiation emitted by the Earth back into space.

How does outgoing longwave radiation relate to Earth's energy balance?

• Outgoing longwave radiation is primarily responsible for solar energy absorption.

• Outgoing longwave radiation increases Earth's temperature by trapping heat.

• Outgoing longwave radiation is essential for maintaining Earth's energy balance by regulating temperature through energy loss to space.

• Outgoing longwave radiation has no significant impact on Earth's energy balance.
  

What factors can influence the amount of outgoing longwave radiation?

• Wind speed and direction

• Surface temperature, atmospheric composition, cloud cover, and surface characteristics.

• Solar radiation duration, intensity, and angle

• Ocean currents
