Energy Balance and Climate Model Quiz

What is the primary reason a planet without an atmosphere emits radiation?

• It has a liquid core.

• It has an atmosphere.

• It has a temperature.

• It has a magnetic field.

In the context of a planet with an atmosphere, what does the term 'albedo' refer to?

• The emissivity of the atmosphere.

• The fraction of solar radiation reflected by the atmosphere.

• The fraction of solar radiation absorbed by the surface.

• The temperature of the planet's surface.

If the albedo of a planet's atmosphere is nearly zero, what does this imply?

• The atmosphere reflects most of the solar radiation.

• The atmosphere reflects very little solar radiation.

• The atmosphere emits more radiation than it absorbs.

• The atmosphere absorbs all the solar radiation.

What additional factor is considered in a realistic energy balance model that is not in a simple model?

• The rotation speed of the planet.

• The gravitational pull of the planet.

• The emissivity of the atmosphere.

• The magnetic field of the planet.

How does the atmosphere contribute to the energy balance in a realistic model?

• By absorbing all incoming solar radiation.

• By increasing the planet's magnetic field.

• By reflecting all outgoing radiation.

• By emitting radiation based on its temperature.
