Which of these is NOT a function of Earth's atmosphere?
a) insulating the planet to keep it warm
b) allowing water to evaporate into space
c) protecting Earth from harmful radiation
d) storing oxygen for living things to breathe

This is the only form of heat transfer that the sun can use to transfer heat to the earth
a) (solar) conduction
b) (solar) radiation
c) (solar) convection
d) (solar) radvection

The greenhouse effect is a dynamic process that affects Earth’s environment. It involves radiation, heat, and gases; it has both positive and negative results. Which of these is a positive result of Earth's greenhouse effect?
a) It traps heat energy from the Sun, creating temperatures that sustain life on Earth
b) It creates an increase in Earth’s temperature, melting ice at the poles and causing ocean levels to rise.
c) It removes volatile organic compounds from homes, decreasing the chances of respiratory problems.
d) It increases when gases are added to the atmosphere, which may cause climate to be warmer than it was 100 years ago.

The beach is hotter than the ocean during the day, so the wind flows from the sea to the land- this is called a?
a) cyclone
b) land breeze
c) sea breeze
d) anticyclone

The circulation of heat through fluids, the less dense fluid rises and the denser, cooler substance sinks
a) evaporation
b) conduction
c) radiation
d) convection

The hole in the ozone layer of Earth has caused negative environmental issues for many years. The decreasing size of the hole in the ozone layer will most likely have which effect on Earth's environment?
a) increased global temperatures
b) increased melting of polar ice caps
c) increased blockage of ultraviolet radiation
d) increased levels of carbon dioxide in the atmosphere

Unequal heating of the Earth's surface causing differences in air pressure on earth is the reason this occurs?
a) the ozone layer
b) global warming
c) auroras
d) wind

This is the type of light that the ozone layer filters out, which causes sunburns and skin cancers
a) microwaves
b) ultraviolet (UV)
c) radio waves
d) visible light

This is the continuous circulation of heat between the land and sea or around large areas of the ocean due to differences in temperatures/ density.
a) convection currents
b) conduction currents
c) sea breezes
d) land breezes

You step on the sand and burn your foot. How was heat transferred to your foot?
a) Conduction
b) Convection
c) Radiation
d) Transpiration

Which layer of the atmosphere contains the ozone layer?
a) stratosphere

a) Thermosphere
b) mesosphere
c) stratosphere
d) troposphere

As you increase in altitude, what happens to the amount of air/ air pressure?
a) They increase
b) They decrease
c) They stay the same
d) Air has no pressure

As you increase in altitude, what happens to the temperatures?
a) They increase
