to block UV rays from getting to Earth

6.
What happens to the density (thickness)/air pressure of the air as you increase in altitude?
a)
density increases
b)
density decreases
c)
density stays the same
d)
density disappears
7.

Why aren't clouds found in the upper layers of the atmosphere?

a)

Because UV rays from the sun destroy them

b)

Because gravity holds the water molecules closer to earth in the troposphere

c)

Because as meteors enter the mesosphere, they burn through the clouds

d)

Because it is too cold

8.

What drives the movement of air on earth?

a)

Gravity

b)

The sun

c)

The moon

d)

The mountains

9.

Why do you feel humidity more in the summer than in the winter?

a)

Because you are outside more

b)

Because there are less clouds

c)

Because warm air holds more moisture than cool air

d)

Because the effects of gravity are more in the summer

10.

Why does water boil at a lower temperature as you go higher in altitude?

a)

Atmospheric pressure is lower, so it it takes less energy for water to reach its boiling point.

b)

Atmospheric pressure is higher, so it takes more energy for water to reach its boiling point.

c)

Temperature is lower in higher altitudes, so water reaches its boiling point faster.

d)

Temperature increases as you increase in the troposphere, so water reaches its boiling point faster.
