2. Which result is most likely to
occur after excessive
withdrawal of groundwater in
coastal areas?
As the freshwater is removed, there will be
an intrusion of saltwater into the water
table.

3. Water has to go
somewhere
Excessive rain will cause an increase in
runoff and infiltration in an area.

4. What happens when the
marsh is gone?
• Marshlands serve as habitat
for many life forms. They also
help in soaking up extra water
and marshlands filter and
cleanse water.
• Destroying a marsh can lead
to decreased filtering of
water.

5. Temperature increases as altitude increases in both the stratosphere and the
thermosphere. What is the main difference between these two layers?
the stratosphere
• The temperature increases in
the stratosphere because ozone
absorbs ultraviolet radiation
the thermosphere
• The temperature increases in
the thermosphere because of
direct exposure to the sun.

6. When is it enough?
• What would most likely
result if more farms were
developed along river basins in
North Carolina?
• Due to runoff from
fertilizers, animal wastes and
compacting of some of the
land, there would be an
increase in water pollution.

7. Which is a major source of air pollution?
small farms raising large numbers of animals such as cows and pigs

8. Which is most often a result of a warm air mass moving
over a cooler air mass?
The result is often an increase in precipitation

9. Wind speed
• Which has the greatest influence on wind speed?
• Differences in the density of adjacent air masses cause
the wind to blow. Colder air is more dense, and it sinks.
Warm air is thinner and it tends to rise. When these two air
mases meet, the movement is often in a circular pattern.
But sometimes the warmer air simply rises quickly causing
an upward draft.

10. Weather or Climate?
• Joan picked up a brochure on
North Carolina and learned the
facts listed below.
• •It may experience either hot,
humid summer conditions or more
moderate summer conditions.
• •The annual rainfall across the
state ranges from 37 to 90 inches.
Which aspect of North Carolina was
Joan focusing on from the
brochure?
• climate of North Carolina http://www.punditcafe.com/wp-content/uploads/2016/11/1-2.png?x10418

11. Which is least likely to
cause changes in
global climate?
A tsunami event certainly can cause a huge
amount of destruction, but it is basically a
one time event. The flooding happens in a
specific area and not over the entire globe.

12. Greenhouse gases in the atmosphere
Burning coal to produce electricity could increase the amount of greenhouse gases in the atmosphere
