What is felt as heat
infrared
How is heat transferred from the sun to Earth?
radiation
The direct transfer of energy by electromagnetic waves is called
radiation
Reflection of light in all directions is called
scatering
13.What absorbs energy from the sun in the atmosphere?
water vapor, carbon dioxide, clouds, dust, and other gases absorb energy in the atmosphere
electromagnetic waves are classified according to
wavelength
independent variable
what the scienist change
dependent
what the scientist can't change
controlled
what the scientist wants to have constant
12.What happens to energy from the sun that is neither reflected nor absorbed by the atmosphere?
It can pass through the atmosphere to the earth's surface
infrared radiation
It has wavelengths that are shorter than those of violet light.
visible light
It is a mixture of all of the colors of the rainbow.
Sunburns are caused by
UV
What absorbs most of the energy that is radiated from Earth's surface?
Water vapor, carbon dioxide, methane and other gases absorb most of the energy that is radiated from the Earth's surface
what is right about infared radiation a. It is invisible. b. It can be felt as heat. c. It has longer wavelengths than red light has. d. It causes sunburn.
abc
11.Circle the letter of each sentence that is true about ultraviolet radiation. a. It makes up most of the energy from the sun that reaches Earth. b. It can cause skin cancer and eye damage. c. It has longer wavelengths than violet light has. d. It can cause sunburns
bd
Circle the letter of each sentence that is true about scattering. a. Short wavelengths of visible light scatter less than long wavelengths. b. Blue light scatters less than red light. c. Scattered light is bluer than ordinary sunlight. d. Scattering explains why the daytime sky looks blue.
cd
14.What reflects energy from the sun in the atmosphere?
clouds, dust particles and gases reflect energy from the sun
The direct transfer of heat from one substance to another substance that it is touching is called
conduction
The transfer of heat by the movement of a fluid is called
convection
Heat is moved through the troposphere mainly by
convection currents
Energy from the sun travels to Earth as
electromagnetic waves
Is the following sentence true or false? Nearly half of the energy in Earth's atmosphere comes from the sun.
false
Is the following sentence true or false? Red light has a shorter wavelength than blue light.
false
Is the following sentence true or false? When Earth's surface is heated, it radiates most of the energy back into the atmosphere as ultraviolet radiation.
false
The process by which gases hold heat in the air is called the
greenhouse effect
process that keeps earth's atmosphere warm
greenhouse effect
Energy that is absorbed by the land and water is changed into
heat
The energy transferred from a hotter object to a cooler one is referred to as
heat
average amount of energy of motion in the particles of a substance.
temperture
What causes the different colors of visible light?
the different colors are the result of different wavelengths of light
The total energy of motion in the particles of a substance is called
thermal energy
How is air temperature usually measured?
thermometer
thin glass tube with a bulb on one end that contains a liquid, usually mercury or colored alcohol.
thermometer
Is the following sentence true or false? Electromagnetic waves are classified according to wavelength, or the distance between waves.
true
Is the following sentence true or false? The greenhouse effect is a natural process.
true
c. It has wavelengths that are longer than those of red light.
ultraviolet radiation
visible light with the shortest wavelength is what light?
violet
