The sun

Which of the following is NOT a role that our atmosphere plays in reducing the amount of radiation the Earth's surface receives?

• greenhouse gases remove radio waves and infrared radiation
• the ozone absorbs ultraviolet radiation
• the atmosphere protects us from solar wind
• x-rays and gamma rays are absorbed by the upper atmosphere

Which of the following is the order of electromagnetic radiation from the Sun by lowest to highest frequency?

• gamma rays, ultraviolet, visible light, infrared, x-rays, radio waves, microwaves
• radiowaves, microwaves, infrared, visible light, ultraviolet, x-rays, gamma rays
• microwaves, ultraviolet, infrared, visible light, x-rays, radio waves, gamma rays
• visible light, radio waves, infrared, ultraviolet, microwaves, gamma rays, x-rays

Where is the energy for the Sun get created?

• in the radiation zone
• in the convection zone
• in the core
• in the Sun's atmosphere

What heat transfer method is used by the Sun to transfer the heat from its core to its surface?

• conduction
• convection
• radiation

What heat transfer method is used on the surface of the Sun?

• conduction
• convection 
• radiation

What heat transfer method is used to get the heat energy from the Sun to the Earth?

• conduction
• convection
• radiation

Where on Earth is conduction used to transfer the heat energy from the sun?

• up in the atmosphere
• very close to the surface
• below the surface of the Earth
• where space meets our atmosphere

Where on Earth is convection used to transfer the Sun's energy to Earth?

• up in the atmosphere
• within a few centimeters above the ground
• where space meets our atmosphere
• below the Earth's surface

A good description of radiation as a means of heat transfer would be

• rising of hot fluids and sinking of cool fluids
• direct contact between a solid and some other material
• waves of energy are transmitted through empty space
• amount of heat energy that can kill you

A good description of convection as a means of heat transfer would

• rising of hot fluids and sinking of cold fluids
• direct contact between a solid and other materials
• waves of energy are transmitted through empty space
• a belief you strongly believe in
