For study, the Earth can be divided into three parts:

atmosphere
lithosphere
ionosphere
stratosphere
hydrosphere
mesosphere

atmosphere
lithosphere
hydrosphere

The major difference between oxygen and ozone is:

the number of atoms in a molecule
the kind of atoms they are made of
the color of the gas
one is a gas and the other is a liquid

the kind of atoms they are made of

The effect of the stratosphere being colder at the bottom than at the top is:

sudden weather changes
no vertical air movement
better radio reception
the separation of gases into layers

no vertical air movement

The trapping of heat by carbon dioxide and water vapor is known as the:

radiation balance
greenhouse effect
radiant spectrum
scattering

food
carbon dioxide
oxygen
sugar

carbon dioxide

The process by which plants make food is called:

True
False

False

The sun provides the main source of energy for many of the phenomena that occur on Earth.
True
False

True

The layer that is warmed from below by the ozonosphere is the

mesosphere

The hottest layer of the atmosphere is the

Thermosphere

Radiation balance means that the amount of radiation gained by the atmosphere_________ the amount of heat lost to space

equals

The atmosphere extends up to an altitude of about:

330 miles
200 miles
200 Km
50 miles

200 miles

Half of the mass of the atmosphere is found below the altitude of______because the air is compressed by the_______of the overlying atmosphere.

3 ½ miles
weight

Which gas is a major factor in causing storms?

ozone
nitrogen
hydrogen
water vapor

water vapor

The atmospheric layer in which most weather occurs is the

troposphere

As you fly up through the tropopause into the stratosphere, what would you expect?

temperature would remain constant

The temperature of the mesosphere decreases with altitude because it is:

heated from below by sunlight
heated from above by the sun
heated from below by the ozone layer
cooled from above by the thermosphere

heated from below by the ozone layer

The atmospheric gases in the thermosphere are heated:

directly by the sun
by the mesosphere
by meteors
by radiation from the Earth's surface

directly by the sun

What practical function is provided by the ionosphere?

produces auroras
charges atoms
heats oxygen and nitrogen
permits worldwide radio communication

permits worldwide radio communication

cosmic
x-rays
light
heat
radio

Exposure to excessive ultraviolet radiation can be harmful to your

body
health
skin

The rapid reduction in life spans after Noah's flood may be due to

a change in the properties of the atmosphere increase in radiation after the flood reduction in shielding effects of the atmosphere

The absence of meteorites within the Earth's rock layers indicates that _____.

the rock strata are young
the rocks formed rapidly
